In theory, database documentation is simple:
design first, document everything, keep it updated.
In practice, that rarely survives real projects.
Schemas evolve fast. Requirements change. Hotfixes happen.
And the first thing to fall behind is always the diagram.
Not because teams don’t care — but because manual synchronization does not scale.
At some point, the ERD stops being a source of truth and turns into a snapshot of the past.
From there, people either stop trusting it… or stop opening it at all.
What worked better for me was changing the model entirely:
Instead of maintaining documentation, I started generating it from the actual model, versioned alongside the project, just like code.
That idea eventually became ForgeSQL — a visual modeling tool where the diagram is not an accessory, but the source that generates:
real SQL
real Docker environments
versioned artifacts in GitHub
No diagrams “to keep updated”.
No separate documentation to chase.
Just one model that stays aligned with reality.
I’m curious how other teams deal with this today:
What actually guarantees that your database diagram still reflects production?
