## **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 The documentation is outdated.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.

### **Without proper data modeling**

New development requires extensive archaeology

Data quality issues compound over time

Integrations are painful and error-prone

Business reporting relies on fragile workarounds

Technical debt accumulates in the data layer

### **With professional data modeling**

Data structures are documented and understood

Naming conventions and standards are consistent

A central data dictionary serves as the reference

New development follows established patterns

Data quality is measurable and improving

**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.

**1**

### **We reverse-engineer what exists**

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

**2**

### **We identify the problems**

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

**3**

### **We design improvements**

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

**4**

### **We establish practices**

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

## **AI Starts with Data Modelling: Why 'Model First' Matters More Than Ever**

See how model first establishes shared semantics, operationalises governance, reduces rework, and gives AI initiatives a dependable data foundation.

- Shared semantics for analytics, data products, and AI
- Less rework through explicit structures and accountability
- Operational governance instead of retrospective documentation
- A practical 90-day plan for AI-ready data foundations
