Quick and easy ERDs for existing databases

Generate ER Diagrams automatically
to save time and effort

Dataedo allows you to create ER Diagrams automatically based on foreign keys: from your database and defined manually in the repository.

Generate ER Diagrams automatically<br>to save time and effort

Create ER Diagrams manually
for full control and clarity

Design your diagrams your way. Rather than adding all tables at once, build meaningful, focused diagrams directly from your data catalog with a simple drag & drop. Dataedo suggests relevant entities you can add next, or you can easily search the entire catalog to find what you need.
