Automatic relationships from database

Dataedo reads foreign key constraints from DBMS and adds table relationships to the diagram automatically.

Add missing relationships easily

It is easy to add relationships in Dataedo data model repository for foreign keys with no FK constraints in the DBMS.

Stories Over Details

Multiple small diagrams

Happy Customers

Christopher Hurd

"We can group different database objects together to present different aspects of functionality. The ER diagrams are invaluable when it comes to this. This is a very well thought out feature. Above all, we use the export to HTML all the time. I’m extremely passionate about properly documenting our databases and managing our information effectively, and it is done thanks to Dataedo."

Antony Liberato

"I had two requirements for an ERD Tool. Pull live objects from SQL, and allow editing relationships without modifying any live constraints. Dataedo does this perfectly. And I really like the export utility, as the PDFs fit right into our document libraries."
