Design and document data models that stand the test of time.

Build data structures that everyone can understand

Your databases are critical, but do teams actually understand how data is structured? erwin Data Modeler helps you design, document, and maintain data models that bridge the gap between business requirements and technical implementation.

Recognizable problems

A scenario you might recognize

Your databases grew organically over years. Documentation is outdated or missing. New team members struggle to understand how data is structured. Changes are risky because nobody fully understands the dependencies.

Undocumented databases

Critical data structures exist only in the database with no design documentation.

Knowledge silos

Only a few people understand how the data is actually structured.

Risky changes

Database modifications are scary because impact is unclear.

Inconsistent design

Different teams create structures with different conventions.

Use Cases

Typical projects and scenarios

See if your situation matches what erwin Data Modeler is designed for.

1

Designing enterprise data architectures

Data structures evolve ad-hoc without clear design or documentation.

Visual modeling with logical and physical layers that capture both business and technical perspectives.

We help you establish modeling practices and design your enterprise data architecture.

2

Documenting existing databases

Critical databases have no documentation and knowledge lives in people heads.

Reverse engineering creates models from existing databases to document what you have.

We reverse engineer your databases and establish documentation practices.

3

Enforcing standards

Different teams create databases with inconsistent naming and structures.

Templates, naming standards, and validation rules ensure consistency.

We define and implement standards that match your organization.

4

Supporting migrations

Database changes are risky because impact is unclear.

Model comparison and impact analysis show what changes will affect.

We support migration planning with model-driven analysis.

Data Modeling Maturity Assessment

Evaluate your current data modeling practices and identify opportunities to improve documentation, standards, and team collaboration.
