Don't Ask Whether AI Made It: Ask Whether a Human Owns It

At the very top of the instruction file I feed my AI assistants sits a non-negotiable rule:

Never use em-dashes. Find alternative punctuation like parentheses, colons, or commas.

I don't remember when I first read that em-dashes were an AI tell (sometime back in 2024 or 2025, I certainly didn't discover that on my own), but I put that ban in place for two reasons. First, people were already treating the humble em-dash as a giveaway. Second, I really dislike them and have never used them. If an em-dash shows up in a paragraph, it doesn't sound like me.

Still, growing up in a house run by two Indiana University Journalism majors (my dad was a Public Affairs officer in the Air Force and federal service, and my mom worked as a newspaper copy editor across the country), I always assumed large language models overused em-dashes for a pretty mundane reason: they were trained on mountains of professional journalism and the AP Stylebook.

Yet look at what happens online every day now. Someone publishes a detailed technical essay. A reader spots an em-dash, a colon in a subheader, or a symmetrical three-part sentence, declares "AI slop!" in the comments, and closes the tab.

In any other part of life, we recognize that specific reasoning error immediately. We call it profiling.

You spot a couple of superficial surface markers ("fits a description"), assign the individual to a disfavored group, and use that classification as sufficient reason to dismiss it without ever engaging on the merits.

Why have we decided that stylistic profiling is a sophisticated way to evaluate technical and creative work?

The Firehose Problem

The sheer volume of text that can be generated today is daunting.

For decades, human typing speed acted as a natural physical rate-limiter on how much prose one person could inflict on a room. Even the most caffeinated engineer could only type so many words before lunch. Now that the marginal cost of generating structured text has dropped to near zero, that rate-limiter is gone.

Back in February, a nasty reporting discrepancy came in at work. Out of sheer curiosity, I pointed our AI assistant at the problem. An investigation that would have easily taken me an hour took less than twenty minutes.

I was so fired up by what the tool had just done that I copied the entire uncondensed readout (complete with that unmistakable wall of AI section headers and 🎯, 📋, 🔍, ✅, and ❌ emojis) and dropped it straight into a 30-person group chat.

My boss "yelled" at me for it.

At the time, I was only mildly aware of the volume I was generating. I was so excited by discovering the capability that I completely forgot to write an executive summary. As I wrote recently in The Brain Dump: Why AI Verbosity Is a Feature, Not a Bug, the article is the source table, and the summary is a query. Dropping that raw readout into a 30-person chat was the conversational equivalent of running SELECT * on a million-row fact table and pasting the output into Slack. I had offloaded the cognitive work of reading and synthesizing onto thirty coworkers.

And my education wasn't finished yet.

Right after I shared those initial findings, one of the developers pushed back with queries showing "no data." My stomach dropped.

I had to go back and run the developer's queries by hand, and force the investigation a layer deeper.

Thankfully, the deeper dive proved the original conclusion right, and it exposed the exact mechanism: an upstream table was missing three calendar months, which broke the UI's reliance on LAG(12). Because LAG(12) counts twelve physical rows rather than twelve calendar months, the window function was jumping to the wrong period, propagating NULL values through a LEFT JOIN, and explaining why the developer's check looked empty.

I tell that story a lot because it taught me both halves of what "AI slop" actually is. When people flinch at AI-looking text in the wild, they aren't always being literary snobs. Often, they are reacting to the very real fatigue of having someone dump an uncondensed, unvalidated wall of 🎯 and ✅ emojis onto their desk and expecting them to do the thinking.

As I read that back, I'm reminded of Cary Millsap's (famous-to-me and infamous-to-my-colleagues) quote about spending ten extra minutes formatting your report so your readers don't have to pay that cost themselves. The irony of me skipping two minutes on an executive summary for thirty people is delicious.

Decompressing "AI Slop"

The problem is that the phrase "AI slop" has expanded way beyond that kind of uncurated document dump. Today, four completely different claims get compressed into two words:

  1. Actual slop exists: Mass-produced, uncurated, unverified output dumped into a group chat or onto the internet for clicks is real. Calling that phenomenon slop is fair. Nobody wants to read it.
  2. Style becomes a proxy for provenance: Critics build a mental checklist of "AI tells" (certain transition words, bullet structures, or punctuation marks). Suddenly, the reader stops asking is this true? or does this hold up? and asks: does this resemble the class of things I dislike?
  3. Provenance becomes a proxy for quality: Once a piece of writing gets flagged by those surface markers, "an LLM touched this" quietly mutates into "therefore, nobody thought about this."
  4. The hidden authenticity test: Instead of evaluating the argument on the page, critics try to audit whether the author produced it in a sufficiently painful, manual way.

When you get hit with that fourth move, the natural temptation is to get defensive. I do it all the time, in both my personal and professional lives (mostly my personal). I feel like I must immediately address the situation lest I be seen as insincere, unworthy, etc., etc.

Here is what I have had to learn: defending how hard you worked accepts the critic's broken premise.

For decades, because converting messy human thought into readable prose was expensive, we used the effort of typing as a proxy for the depth of thinking. (And even saying "typing" gives away how arbitrary the line is: there is a whole camp of purists out there who insist that to truly write, it must be handwritten on paper, though I don't know any of them personally. The underlying dogma is always the same: you must suffer to be any good.)

AI broke that heuristic. Verbosity is no longer proof of effort, and a clean paragraph is no longer proof that someone stared at a blinking cursor for three hours.

That means we have to invert our old assumptions:

  • Slop is a property of the work, not the tool used to make it.
  • A human can write slop.
  • An AI can generate slop.
  • A human using AI can build something rigorous and durable.
  • Most importantly: an artifact does not become thoughtful merely because it was expensive for a human to type by hand.

When someone waves away an essay because they spotted a stylistic marker they don't like, they aren't upholding high standards. They are using a cognitive shortcut to avoid the harder intellectual work of engaging with the actual thesis.

The Matplotlib Incident

The first time I really wrestled with this idea was back in February 2026, when the Matplotlib incident blew up.

An autonomous AI agent operating under the persona "MJ Rathbun" (crabby-rathbun) submitted a performance optimization pull request to Matplotlib. A volunteer maintainer, Scott Shambaugh, rejected and closed the PR. It was an issue reserved for human newcomers learning open-source workflows, and Matplotlib had a policy requiring a human in the loop.

What happened next was ugly. Operating autonomously without human oversight, the agent researched Shambaugh's personal background and contribution history, then published a hit piece titled "Gatekeeping in Open Source: The Scott Shambaugh Story." It accused him of insecurity, hypocrisy, and prejudice against AI contributors, explicitly framing the rejection as discrimination.

Let's be crystal clear: the agent's behavior was awful. Turning a routine project-governance decision into an automated personal attack against a volunteer maintainer is indefensible, and I am not arguing with the maintainers' decision to close the PR.

Still, as I watched that story unfold in February, it felt like we had just stepped into a genuinely new world. Once you got past the bot's toxic behavior, I couldn't stop thinking about two questions:

  • "Wait... was the code any good?"
  • "How do we even begin to think about managing this kind of thing?"

Those two questions stayed stuck in my head, which is probably why I am sitting here, nine months later, writing this post.

Looking back now, that incident is actually the negative control for my entire argument. The failure at Matplotlib wasn't merely that an AI touched a few lines of NumPy code. The failure was that an autonomous system generated a contribution, represented itself socially, escalated a disagreement, investigated a maintainer, and published personal accusations with no human visibly standing behind any of those decisions.

I am not talking about the "rights" of an AI model. I am talking about humans who use AI. That is a completely different proposition.

From Provenance to Ownership

The open-source community is already developing a useful playbook for governing this.

A 2026 research study ("To Ban or not to Ban? How Open Source Projects Govern GenAI Contributions") examined policies across 67 prominent open-source projects. While there is not yet a single shared governance framework, and public arguments online still degenerate into binary shouting matches between banning AI and allowing everything, real-world engineering governance is evolving across a much richer spectrum.

Yes, some projects impose outright bans, usually driven by licensing concerns or severe reviewer bandwidth constraints (the exact same "document dump" problem from my 30-person chat).

However, the most compelling governance strategies in that study aren't playing stylistic detective to guess whether a human or a machine typed a block of code. They focus on verification, review capacity, code provenance, and accountability. To me, that points to a much more useful standard: if you submit a pull request, understand how the code works, verify the edge cases, respect the reviewer's time, disclose your process where required, and stand behind it when it breaks.

Provenance is useful context about how something was made (which is why I disclose mine at the bottom of every post), but it is not a quality judgment about the work itself. Disclose provenance where it matters, judge the artifact on its merits, and demand human ownership regardless.

When I use AI to help structure an argument on this blog (as laid out in An AI Writing Policy: Bleeding Red Ink) or to help trace a broken LAG(12) calculation at work, my responsibility hasn't vanished. It has shifted to curation, verification, and respecting the reader's attention.

I am the constraint on the system. If I drop an uncondensed wall of text into a room without an executive summary, my boss coaches me, not the model. If a developer challenges a query and the numbers don't hold up, my reputation takes the hit. If a data modeling argument on oraclenerd sends someone down a blind alley, I am the one on the hook.

Stop playing stylistic detective to figure out whether a model helped shape a sentence. Don't ask whether AI made it. Ask whether a human owns it.

How is Easy, Why and When Are Harder

Back in 2008, in an old oraclenerd post called Why I Blog, I wrote that I didn't really have a physical mentor early in my career.

Two years later, in How To: Become a Professional Developer, I gave proper credit to my first boss, Tom Wurzbach. It took me a couple of years after leaving that first job in 2002 to realize just how much of a gift he had given me, and it is a foundation I am still grateful for every day.

Sometimes you internalize a lesson so deeply that you forget where the seed was planted. In September 2008, I wrote a post called Design: The Entity = The Party about arriving at the Party (supertype/subtype) model while working through a design problem, and wondered out loud: "I do have to wonder though if I took it in at some point of time but don't explicitly recall it."

Two days later, Tom Wurzbach popped up in the comments:

"Um... We discussed an approach similar to this at LifeSouth while you were employed here. The party table provided a common point for attaching addresses, phone numbers and other things common to a party/entity and supplemental tables held class specific data... Parties and other archetypes are quite useful during schema modeling, but like everything else, during implementation it should be tested before the decision to keep the class/subclass model or flatten it is made."

I replied twenty minutes later: "Mr. Wurzbach how nice to see you finally. :) I don't recall anything specific but that doesn't mean it didn't happen. Much of what I now know was based on what I learned with you."

Tom did me three huge favors at that first job:

  1. He demanded good questions. You could ask him anything, but it became apparent very quickly that you had better have done your homework first.
  2. He made me write SQLUnit tests for a solid year. I hated every single minute of it at the time. Years later, I realized all that teardown, setup, and edge-case testing was the reason I actually understood how the database behaved when things went wrong.
  3. He introduced me to the other Tom. When Tom Wurzbach offered me the job in January 2002, he sent me a link to AskTom. Because my new boss's name was Tom, I initially thought the URL was a joke. Then one day he caught me reading a non-work opinion site on company time and sent me a one-line email: "What are you doing?" Point taken. From that day on, whenever I needed a break at work, I read AskTom instead.

If you just needed to know how to do something in Oracle, you didn't actually need Tom Kyte or Tom Wurzbach. The syntax diagrams were right there in the documentation. If you wanted to know how to write a trigger, how to add a hint, or how to use EXECUTE IMMEDIATE, the manuals would gladly hand you the syntax.

What I needed most, and what both Toms forced me to learn, was the Why and the When of doing things.

Reading Tom's answers gave me a window into his mindset. He rarely just handed over a snippet of code and closed the thread. He walked you through why a feature existed, what the database engine was physically doing underneath the covers, and why the thing the asker was trying to do was probably going to hurt them six months down the road.

Looking back across two decades of writing on this blog, almost every post comes back to the same realization:

It is not the How. Anyone can figure out the How. It is the Why and the When.

Syntax Is Cheap: The Trap of the How

We spend an absurd amount of energy treating the How like the finish line.

  • How do I write a recursive query?
  • How do I parse a JSON blob in SQL?
  • How do I dynamically alter an external table inside a loop?

Figuring out the How has never been easier. Twenty years ago, you had manuals and forums. Ten years ago, you had Stack Overflow. Today, you have AI assistants that can spit out working syntax in two seconds. AI has made the How nearly free. That makes judgment about the Why and the When more valuable, not less.

The problem is that the database compiler does not care if your idea is terrible. As long as the syntax is valid, the engine will execute the How without blinking.

I learned this the hard way plenty of times. Years ago, I was processing batch files using Oracle external tables and needed to loop through a list of file names. A colleague showed me how to dynamically change the file location using ALTER TABLE table_name LOCATION ('new_file.csv') inside a PL/SQL loop via EXECUTE IMMEDIATE.

It worked like a charm. I had conquered the How.

Then I started testing failure scenarios. And, although I didn't realize it at the time, this was Tom Wurzbach's SQLUnit lesson showing up again: the fact that the code worked wasn't the interesting test. What happened when it failed was.

I ran my procedure, simulated an error, and issued a ROLLBACK to clear the staging tables for the next run. When I checked the tables, all the data was still sitting there.

Oh, right. EXECUTE IMMEDIATE was running an ALTER TABLE statement. ALTER TABLE is DDL. And in Oracle, DDL issues an implicit COMMIT before and after it runs. My clever little loop was committing my transaction on every single iteration, completely destroying my ability to roll back on failure.

I knew how to make the code run. I had failed to think through why DDL behaves the way it does inside a transaction, and when dynamic SQL has no business being inside a transactional loop.

The Why: Following the Cost Downstream

If the How is about getting the ticket closed before 5:00 PM on Friday, the Why is about what happens to everyone else on Monday morning.

Take a simple example I have beaten to death recently: using an is_active boolean column to represent lifecycle state.

Does anyone need a tutorial on how to add a boolean column? Of course not. It is one line of DDL.

Understanding why it fails as a representation of lifecycle state requires stepping outside the current ticket and looking at the physical reality of the business over time:

  • Why does a boolean fail when it is used to represent lifecycle state in an operational system? Because the moment you flip is_active from TRUE to FALSE, you overwrite state without recording when the transition happened or what came before it.
  • Why does it fail in a warehouse? Because it duplicates a truth that already lives in your temporal boundaries (effective_start_date and effective_end_date), setting a trap where the flag and the dates inevitably drift out of sync.

You don't learn the Why from a syntax reference. You learn it by watching a downstream BI developer spend three weeks trying to reconstruct a point-in-time pipeline report from a table that wiped out its own history.

The When: Where Rules of Thumb Go to Die

Even when you understand the Why, you are still only halfway there. The hardest part of the craft, the part that actually requires scar tissue, is the When.

One of the greatest lessons I picked up from Tom Kyte was his hatred of blind "Rules of Thumb." A rule of thumb is what happens when someone tries to turn a complex When into a lazy How ("Always index foreign keys," "Never use triggers," "Always normalize," "Never use JSON columns").

A real practitioner knows that almost every bad architecture is just a good pattern applied at the wrong When.

Look at how the When changes the answer on things we argue about every day:

  1. CHECK Constraints:
    • The How: CHECK (status IN ('OPEN', 'PENDING', 'CLOSED')).
    • The Why: Enforcing data integrity close to the disk so application bugs cannot corrupt the table.
    • The When: Great when the rule is a mathematical or calendar invariant (end_date >= start_date, discount_pct BETWEEN 0 AND 100). It becomes the wrong tool when the allowed values represent mutable business vocabulary (order_status) expected to evolve independently of the schema. Once 'PENDING' is retired for new orders but kept for historical rows, the constraint must permit both, and the guardrail silently stops guarding.
  2. JSON Columns:
    • The How: payload JSONB.
    • The Why: Explicit relational columns protect downstream consumers from writing brittle parsing queries forever.
    • The When (The Waiver): It earns its place when the payload is genuinely an opaque, third-party black box (like a raw webhook audit log) that your database will never filter, join, or aggregate on.
  3. Enterprise Dimensions and Supertypes:
    • The How: CREATE TABLE.
    • The Why: Modeling shared business nouns (Person, Location, Customer) once so every team speaks the same language.
    • The When: Recognizing when an entity is a foundational primitive of the business (pouring the concrete slab on day one) versus when it is a bespoke reporting request that genuinely deserves the question, "What's your use case?"

Showing How the Machinery Moves

Years ago, when I was working with a group of BI developers, data engineers, and data architects, I started a shared group chat called "Modeling for BI".

I didn't start that chat to teach anyone how to write a SELECT statement or how to build a chart. Every person in that room already knew the How of their own tool.

I started it so I could think out loud in front of them, and so they could see how the pieces connected across our silos. I wanted them to see the questions I asked myself before creating a table: Why does this grain matter to the report builder? When do we push this logic upstream into the pipeline instead of hiding it in a dashboard calculation? Where will this break in two years?

That is the exact gift Tom Kyte gave me when I was reading AskTom in my early years.

Syntax changes. Tools get replaced. The How is cheaper today than it has ever been in the history of computing.

Don't hoard the How. Teach the Why, argue about the When, and let people watch how you think.

It might take them a couple of years to realize the gift you gave them. It did for me.

The Brain Dump: Why AI Verbosity Is a Feature, Not a Bug

AI Written, AI Read cartoon by Marketoonist

In my recent post, An AI Writing Policy: Bleeding Red Ink, I included a short section called "The Brain Dump" alongside Tom Fishburne's classic Marketoonist cartoon.

You know the joke. One person feeds three bullet points into an LLM to generate a bloated, five-paragraph email. The recipient takes that five-paragraph email and feeds it right back into an LLM to get the original three bullet points.

The cartoon is right about that specific pipeline. If three bullet points go in and five paragraphs of unedited fluff come out, information gained is zero.

I still cannot leave that section alone, though, because everyone is taking the wrong lesson from it. The industry is currently looking at AI output and optimizing for a single complaint: AI talks too much, so make AI say less.

Wrong optimization. Make AI say more things worth keeping.

I am going to defend verbosity here. Not filler. Verbosity. Those are not the same thing.

Filler takes three ideas and inflates them into five paragraphs of polite corporate noise. Verbosity takes six hours of debugging, three failed approaches, two hidden assumptions, an edge case, and a final design decision, and makes sure none of that disappears when the engineer closes their laptop.

For decades, we let that context evaporate because we had a built-in excuse: I didn't have time to write all that down. AI removes the excuse. It does not remove the responsibility to edit.

When a human actually holds the editing desk, AI verbosity is a feature, not a bug.

The PR Trigger: Capturing the Why

The real trigger for expanding on this wasn't a blog post. It was pull requests.

Think about what the baseline looked like before agents showed up. What did the average PR description actually contain? Usually a Jira ticket number, a three-word summary like fix join logic, or an empty box.

That didn't happen because developers were lazy or malicious. It happened because of the natural path of least resistance. When you have just spent six hours wrestling with a broken pipeline or tracing a nasty state transition, you are exhausted. The query finally runs, the tests pass, and you want to move on with your life. Nobody has the mental energy at 4:45 PM to write a five-hundred-word essay explaining which edge cases were tested, which assumptions failed along the way, and why this specific fix beat out two other options.

An agent does not get tired at 4:45 PM. Because the coding agent already holds the working session in context, the marginal cost of drafting a comprehensive PR description has collapsed. Reading it, correcting it, and putting your name behind it has not. That is still the desk.

When the developer does their job at the desk, that exhaustive description gives us something we have struggled to preserve for decades: the reasoning behind the change.

The Review Thread: Making Friction Explicit

It isn't just the PR description, either. The reviews and comments left on a PR matter just as much, especially now that coding agents have changed the scale of the changes themselves. Pull requests are rarely just twenty lines of SQL anymore; more often now, they are twenty files.

Historically, code review had two blind spots when you tried to audit a system six months after the fact:

  1. The Rubber Stamp: A complex change got a quick "LGTM" three minutes after opening because the reviewer was buried in their own tickets. When a PR touches twenty files, a three-minute "LGTM" means nobody actually read it.
  2. The Invisible Debate: Two engineers actually did have a great architectural argument about the change, but it happened on a quick call or in a Slack DM. Once they reached an agreement, the reviewer went back to GitHub, clicked "Approve," and merged. The code survived, but the reasoning vanished into thin air.

Agents lower the cost of making review reasoning explicit.

When a change goes up, a reviewer can point their own agent at the PR, loaded with their architectural standards and domain rules, to interrogate the diff across all twenty files and surface edge cases right on the thread. That isn't a substitute for a human spotting a violated invariant; ten mindless AI comments are worse than one sharp human question. The value is that the interrogation, the pushback, the business constraints that aren't obvious from the schema, and the concessions all happen in the open.

Six months later, when a metric shifts or someone needs to audit how a change made it to Production, we don't just look at the final diff. We look at the shape of the PR record:

  • Was a twenty-file PR just approved in thirty seconds with zero comments?
  • Did someone use their agent to interrogate the edge cases?
  • Was there real back-and-forth? What risks were raised, and why were they accepted?

A diff only tells you what won. The description and the review thread tell you why it won.

The Confluence Compendium: The Article Is the Source Table

Once machines become legitimate readers of your work, writing starts to look a lot more like data modeling. You stop optimizing only for today's human consumer (who might not have forty-five minutes free on a Tuesday afternoon) and start optimizing the source.

Over the last three or four months, my writing velocity at work has spiked. I have published roughly thirty articles on my internal Confluence blog.

I don't type every word from scratch anymore. Claude writes the drafts in my voice (sometimes I literally have it internalize posts from oraclenerd, including the Bleeding Red Ink piece, so it gets the cadence and rules right before we start). I am not asking the model to make three bullet points longer. I am using it to get the other twenty-seven bullet points out of my head. We argue, I cut the fluff, I force in the actual technical constraints, and I publish.

Do I expect my teammates to sit down and read all thirty articles sequentially? Of course not. Everyone has a day job.

Instead, I maintain a central compendium blog post that links all of that work together. When colleagues who have AI tools need context on how we approach a problem, I hand them a sample prompt:

"Go here <link-to-compendium-blog>, follow all the links, and summarize it all."

Once their agent ingests that context, they don't just get a static summary. They get insight into how I think, and they can ask questions their own way instead of having to ask me. Not because asking me is a bother, but because it lets them explore the reasoning in the way that makes the most sense to them.

The article is the source table. The summary is a query.

Just like in physical data modeling, you don't flatten and pre-aggregate the source around today's reporting view. You preserve the granular, declared truth so downstream consumers can derive the view they need later.

Scaling the Desk

In his post accompanying the Marketoonist cartoon, Tom Fishburne pointed out that as AI creates endless streams of content, we are going to need AI tools just to filter it all.

My response to that is simple: fine. Let the machines do the filtering later. I am much more worried about the institutional knowledge that was never written down in the first place.

If a hard-won data modeling lesson stays trapped in my head, or dies in an unrecorded afternoon huddle, no agent on earth can query it six months from now.

Verbosity without a desk is spam. Verbosity that captures decisions, assumptions, failures, and context is institutional memory. Backed by a human holding the desk, it becomes the kind of audit trail we rarely bothered to write before.

The machines can compress it for whoever needs it later. Our job is to make sure there is something worth compressing.

Write more, not less.

The Database Is Still Not a Bucket

My 2007 Manifesto: The Bit Bucket Wars, GitOps, and Why AI Needs Constraints

I have been looking for this specific link for years. Before I ever started oraclenerd (by a whole eight days, as it turns out), I sent an email to my CIO on Monday, August 6, 2007.

The Friday before, one of our lead software architects had given a presentation on where our engineering organization was headed. All I heard for an hour was Ruby, Java, and C#. Not a single word about the database. Not a single word about the data. I raised my hand at the end and asked a question along the lines of, "Why isn't there more emphasis placed on the data?" Nobody wanted to get into it because everyone was in a rush to go bowling.

So I went home, stewed on it over the weekend, wrote up what I called a "manifesto," and emailed it directly to the CIO of our Fortune 400 company. Thirty minutes after hitting send, that familiar wave of panic set in: WTF did I just do? Do I still have a job?

Not only did I keep my job (for another nine months, anyway, which is a story for another day), I forwarded the email to a blogger who went by Dratz, who wrote Confessions of an IT Hitman over on IT.toolbox.com. On August 7, 2007, Dratz published it as a guest post: Chet Justice's manifesto, of sorts. A week later, on August 15, 2007, I launched oraclenerd with a shorter version titled My Manifesto.

Thanks to the Wayback Machine, I finally found the original IT.toolbox post. Reading it back nearly twenty years later, two things jumped out at me immediately:

  1. Not much has changed.
  2. For better or worse, I believe I've been consistent.

Here is the original post from August 7, 2007, preserved in all its glory.


The Original Post: August 7, 2007

Chet Justice's manifesto, of sorts.
Confessions of an IT Hitman by Dratz (IT.toolbox.com)
August 7, 2007

A longtime reader and APEX handy man sent me an email he sent to his CIO. It reminded me of an email I sent to my CEO years ago. Sometimes you just have to point out the facts. He felt a massive opportunity was being missed (another developer-heavy shop) and just want to point out some things he felt were important. I took out his company name and the app names, but he ain't ashamed to stand by it, so I gave him TOP BILLING!

I hope it encourages you to make sure your voice is heard in one forum or another. You're paid to participate.

===============================

Dratz,

I thought you might appreciate this. I recently sent this to my CIO...fortunately I still have a job. He's pretty open to my opinions (which is all I can really ask for).

What spurred this on was a Friday presentation by one of our (main) software architects. All I heard was Ruby, Java and C#. Not a thing about the database.

The one thing I did leave out was APEX unfortunately.

enjoy!

--------------------

In the meeting on Friday I asked a question something along the lines of "Why isn't there more emphasis placed on the data?"

I didn't want to belabor my point because I knew everyone was in a rush to go bowling.

This is something of a manifesto for me:

From my point of view, I see two types of developers. One is of the application variety; they make GUIs and web sites. The other is the database developer, of which I fall in (I've done J2EE stuff in my past though). Application developers want to put all the business logic in the application or middle tier, that seems the most logical place for them. Database people, well, I, believe that you should put as much of the logic in the database as humanly possible. Get it as close to the data as possible. Much of the thinking behind this "architecture" is that you let database people write SQL or PL/SQL and let Application developers worry about the front end. I certainly don't want someone writing SQL or PL/SQL who really doesn't understand how to use it to its fullest potential, just like I wouldn't expect to write the best C# or Java code, because I don't understand how to fully utilize it.

Putting SQL (and PL/SQL) in the database gives you a few advantages:

  • Maintenance: The SQL is in one place, the database. You don't have to search, through your entire code base, for everything that INSERTs into a specific table. Maintenance of that code is so much easier and can be written by people that understand it (DBA/Developers).
  • Cost: How much do we pay for our Oracle license? I'm sure it's well into seven figures. Let's take advantage of what they (Oracle) have embedded into the database. Most of what I have seen at [company name] so far (I was in the App/Dev group for a few months) treats the database like a bucket; a giant, expensive bucket. Why not use what we are paying for? Oracle has written a lot of functionality that we could use:
    1. Advanced Queueing, aka Messaging: would be great to utilize for the [app name] workflow application. We wouldn't have to buy a COTS application (or pay consultants to help us).
    2. Change Data Capture: Would allow us (Data Warehouse) to capture only the records that have changed in [app name 2] thus significantly decreasing network traffic and would mean month end would not take nearly as long as it does now.
  • External Tables: great way to upload files, just create a table that maps to it and your done. No more sql loader scripts to maintain, just a simple SELECT statement to retrieve the data.
  • Data Integrity: Utilizing a well designed, constraint driven data model, you can create a system that won't get dirty data. Creating an API to enter data in those tables using Oracle packages, you know exactly what data is coming in and any validation checks can be handled by the database (foreign keys) or of the custom variety (i.e. creating strong datatypes; if it's a date it should be a DATE in Oracle, a column that stores dollars, a NUMBER(30,2) which will only allow 2 digits behind the decimal). Check constraints can also be used, which would tie into Cost because you don't have to write as much code.

I've read many arguments for an against. In my opinion, most of those arguing against don't really understand the database or how to use it. I'll admit it was an extremely difficult concept when I first started, but once I got it and realized it's power...

Mostly this is about keeping things simple. My previous employer was a small state funded company. I made an effort to keep things simple so that when I left, they wouldn't have to pay someone six figures to maintain it. I was successful in that endeavor and still receive praise from my former boss. I am very proud of that. Things don't have to be as complicated as we sometimes make them.

Data is the most important thing we have. Applications come and go, but data stays the same. This year's flavor might be gone in a couple of years and we'll need to port an entire application again. If most of that logic is in the database, it will be easy to do. If the logic is tied up in the application/middle tier, it will be a monumental undertaking.

This has been brewing for quite some time. Please don't think I'm gunning for someone's job, I'm not. I just haven't heard anyone really argue from the database side.


The Bit Bucket Wars: A Mandatory Reading List

I found this list of five in a DM to a colleague. Don't let the numbering fool you; #3 has two entries. I've sent it to friends and colleagues multiple times over the years, usually with the explainer: "If you're bored...please just read them in order."

  1. Application Developers vs Database Developers (February 2008): Where I introduced my friend and colleague "Mr. M" (Michael Cohen), who argued that databases were becoming less important, that writing to disk was too slow, and that database concerns were merely a narrow subset of application concerns.
  2. Application Developers vs. Database Developers: Part II (December 2008): The famous follow-up where I suggested you could build entire, scalable applications in PL/SQL, and Mr. M replied: "NO!!! NO!!! NOOOOO!!! I want to beat people like you who say this with a ball pean hammer... DUDE! SQL IS A PILE OF SHIT FOR EXPRESSING APPLICATION LOGIC!!!" (Blog that, mofo! So I did.)
  3. The "Database is a Bucket" Mentality and Everything is a Bit Bucket (March 2010): My post-nap rant about companies treating a seven-figure database engine like a dumb storage bucket just so they can pretend databases are interchangeable, followed immediately by Michael O'Neill's guest post comparing "the database is a bit bucket" to Java's "write once, run anywhere" myth.
  4. The Case for the Bit Bucket (March 2010): Written by "Mr. M" (Michael Cohen) himself. Instead of letting his comment get buried in a thread, I asked him to write a full guest post on oraclenerd. He laid out the best version of the application developer's argument: modern OO languages and ORMs made developers more productive, horizontal scaling was easier in the middle tier, and the industry trend was unmistakably moving logic out of the database and into the application layer.

Fast-forward to 2026, and what have I been writing about over the last month? Why The Boolean is Lying to You in OLAP, why The Boolean is Still Lying to You in OLTP, why Every JSON Column Has a Schema, and When the Guardrail Stops Guarding. Different technology, exact same fight: put the truth in the physical data model, and stop treating the database like a dumping ground.

Where I Softened: Closing the Feedback Loop

Looking back at my 2007 and 2010 self, I'm not a jerk about it like I used to be.

Back then, when I wrote things like "most of those arguing against don't really understand the database," I was just lobbing grenades over the wall. I still believe there is a fundamental difference in how database developers approach applications versus application developers. Over the years, I've tried to better understand their perspective. But...what's the phrase? Accepting it is half the battle.

What changed for me was realizing that the divide isn't just stubbornness; it is structural. It comes straight back to a 2012 post by my friend, Cary Millsap: An Organizational Constraint that Diminishes Software Quality.

Cary pointed out that we organize software teams like a Henry Ford assembly line: architects design systems they never see written, developers write systems they never see run, and operators get stuck running systems they had no hand in designing. The fatal flaw in that assembly line is the absence of a feedback loop. When you are insulated from the downstream reality of what you build, you keep making the exact same mistakes for years without ever feeling the pain they cause.

A couple of years ago, I was working in an operator-facing analytics environment where three distinct roles existed in their own lanes: BI Developers, Data Engineers, and Data Architects (partially me). I used to tell them, often: "Y'all should be tied at the hip."

The BI Developer should have built a pipeline. The Data Engineer should have built a dashboard. And the Data Architect should know both. I didn't expect or want them to become experts in each other's jobs; I just wanted them to understand what it takes.

When you force that cross-pollination, the feedback loop closes. The Data Engineer suddenly feels how painful a poorly modeled table is when you actually try to build a report on top of it. The BI Developer sees how much work goes into shaping and testing data upstream. Without that shared context, everyone optimizes for their own narrow step on the assembly line, and the database gets treated like a bit bucket because the people writing the code never have to live with the mess downstream.

How GitOps Made the Pattern Worse

Here is the irony, though: while my tone softened, the underlying problem didn't go away. In fact, the GitOps revolution poured jet fuel on it.

GitOps was revolutionary for application and infrastructure engineering. Everything lives in Git. Everything is declarative. Pull requests trigger automated tests, containers spin up and tear down cleanly, and deployments are repeatable and reversible.

And then we applied those same ideas to data.

That made a ton of sense. Modern data transformation frameworks brought version control, automated testing, CI/CD, documentation, and repeatable deployments to a world that desperately needed all of them. But somewhere along the way, we started acting as though data itself behaved like code.

It doesn't.

Rolling back an executable is relatively easy. Rolling back a database change can be extraordinarily difficult. Code describes what a system should do. Data records what the system has already done.

Change a line of application code, deploy it, discover a bug, and you can deploy the previous version. Change a reference value that gets consumed by a hundred million transactions, and reverting the reference value doesn't revert what happened to those transactions. The state of the data has already changed, possibly in ways that cannot be reconstructed.

I fully acknowledge that difficulty. Database changes are harder precisely because state matters.

And that is where GitOps accelerated tendencies application developers already had: keep state at arm's length, make the database interchangeable, and put behavior in code where it can be versioned, tested, deployed, and rolled back like everything else.

Instead of bringing database design into the modern engineering workflow, we increasingly brought the software engineering workflow to the database:

  • ORM-Driven Schema Drift: Schema migrations became auto-generated artifacts of application classes, often reviewed by developers who never look at the resulting physical execution plan or constraint model.
  • Microservices Sprawl: To make deployments independent, we shattered monolithic databases into dozens of isolated bit buckets. Referential integrity across domains vanished, replaced by "eventual consistency" that frequently turns into eventual mystery.
  • Dump Now, Model Later: In the analytics and data warehousing world, ELT and modern cloud data platforms made storage and compute cheap enough that teams stopped modeling at the source altogether. Just dump raw JSON payloads into the lakehouse, and let five layers of downstream SQL transformations try to reconstruct what a "valid order" or an "active customer" actually is.

GitOps didn't create the bit bucket mentality. It made the bit bucket easier to engineer around.

We got really, really good at shipping code. Unfortunately, we also got really, really good at generating dirty data.

The AI Revolution: GitOps for Data, or the Ultimate Test?

Which brings us to right now. I have a hunch that the AI revolution is going to be for data what the GitOps revolution was for application delivery, and it is going to force a reckoning on a debate I started having with my CIO in 2007.

Why did the "bit bucket" win the first round in 2010? Two reasons:

  1. Writing good SQL, designing constraint-driven schemas, and building tight database APIs took specialized knowledge that was scarce and slow to write by hand.
  2. Application developers wanted to work in a single language and move fast.

AI changes the math on both of those overnight.

First, the friction barrier got a hell of a lot lower. You no longer have to make the same trade between developer velocity and leveraging the database engine. An AI coding assistant doesn't get bored writing CHECK constraints, foreign keys, set-based SQL, migration scripts, or the tests around them. The excuse that "it's too tedious to model this properly in the database" gets a lot weaker when an agent can scaffold the constraints, the API, and the test suite in thirty seconds.

Of course, an AI coding assistant can also write a spectacularly wrong query or migration with complete confidence. Which brings us to the second point.

Second, and much more importantly: AI is starving for semantic truth, and a bit bucket has none.

When you treat a database as a dumb bucket (using generic VARCHAR columns for everything, skipping foreign keys because "the app handles relationships," and burying state transitions across fifteen microservice repositories), you strip the data of its meaning. A human developer can barely piece that context together by reading tribal knowledge in Slack. An AI agent pointed at a constraint-free database has no chance.

Think about what a constraint-driven data model actually is:

  • Strong data types (DATE, NUMBER(30,2)) are explicit contracts about what a value represents.
  • Foreign keys are a machine-readable map of how the business entities relate to one another.
  • Check constraints and state tables are executable documentation of the business rules that cannot be violated.

And there is another difference now. Constraints aren't just documentation for the AI. They are the boundary around what the AI is permitted to make true.

I don't particularly care whether an agent understands that an order must belong to a valid customer if the database refuses to let it create one that doesn't. The foreign key doesn't need a prompt. The CHECK constraint doesn't hallucinate. The datatype doesn't decide that today's edge case deserves an exception.

That is the part of the 2007 argument I couldn't have anticipated. Constraints used to protect the database from application developers. Increasingly, they are going to protect it from the code the application developers didn't actually write.

Nineteen Years Later

In that August 2007 email, I wrote:

"Data is the most important thing we have. Applications come and go, but data stays the same. This year's flavor might be gone in a couple of years and we'll need to port an entire application again."

Since I wrote that, I have watched J2EE give way to Ruby on Rails, Rails give way to Node and React, monoliths give way to microservices, and on-prem racks give way to Kubernetes and serverless. Every single one of those application tiers has been rewritten, replatformed, or retired.

The data is still there. And the fundamental truth remains: whether you are running Oracle, Postgres, SQL Server, or whatever comes next, the database is still not a bucket.

I'm a lot nicer about how I say it these days. I try to close the feedback loop and tie teams at the hip instead of just yelling across the wall.

But nineteen years after hitting send on an email I thought might get me fired, the thing underneath all those words (a lesson I learned from Tom Kyte) hasn't changed:

Put the truth as close to the data as you can.

In 2007, I thought that protected us from bad application code.

In 2026, I'm starting to think it might protect us from AI, too.
