Quick and easy ER diagrams for existing databases

Drag & drop
Rather than adding all tables at once, create meaningful diagrams from data catalog with drag & drop.
Suggested entities and easy search
Dataedo suggests you entities that you can add to diagram next so or you can easily search the entire catalog for tables so creation of diagrams is quick and pleasant.

Visualize and document table relationships

Dataedo allows you to understand, document and visualize relationships between tables (foreign keys), regardless of the actual schema implementation and constraints.

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
Build easily multiple small diagrams to really explain data entities and relationships.
Show key columns only
Hide unnecessary details from diagrams to show only what tells the story.
Provide meaningful aliases
Tables and columns can have confusing and misleading names. Dataedo allows you to provide aliases for names to add meaning on top of physical model.

Share diagrams with complete documentation

Dataedo exports diagrams together with complete database documentation in HTML and PDF.

Our customers

Christopher Hurd
Data Warehouse Engineer


"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
Database Administrator


"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."
