A scenario you might recognize

Your development team needs to add a new feature. Simple enough - just add a few database tables. But nobody is quite sure how they should relate to the existing data structures. The documentation is outdated. Or missing entirely.

The undocumented database

The database has grown organically over years. Column names are cryptic. Relationships are unclear. Tribal knowledge lives in the heads of people who have moved on.

The duplicate data

Customer information exists in three different tables. They rarely match. Which one is the source of truth? It depends on who you ask.

The integration nightmare

Every time you need to integrate with another system, it takes weeks of analysis just to understand what data you have and where it lives.

The performance mystery

Some queries take forever. Is it missing indexes? Poor schema design? Nobody has time to analyze it properly.

The difference is clear

It is not about adding technology for its own sake. It is about having the visibility and control to do your job well.

Current state

Without proper data modeling

New development requires extensive archaeology

Our approach

How we help you get there

We bring deep expertise in data modeling, including decades of experience with erwin Data Modeler. We help you create order from chaos.

We reverse-engineer what exists

Starting from your databases, we build models that document reality. This becomes your baseline.

We identify the problems

Where are the inconsistencies? The redundancies? The missing relationships? We surface what needs attention.

We design improvements

Together, we create target-state models that address the issues while being practical to implement.

We establish practices

Standards, governance, tooling. We help you maintain data model quality going forward.
