Free Data Modeling tools

There are a plethora of free and opensource UML modeling tools available in the market. But there is very little awareness regarding free database modeling tools. Jotting down a few free tools that are very good for ER modeling and support most popular databases for script generation.

  1. Oracle SQL Developer Data Modeler: This cool modeling tool from Oracle is actually free! It supports physical model creation for SQL Server, IBM DB2 and ofcourse Oracle DBs.
  2. DBDesigner: In the past, I have used this extensively when working with MySQL databases.
  3. MySQL Workbench: Another good tool if you are using MySQL.
  4. Aris Express: Software AG's popular Enterprise Architecture tool ARIS now comes with a express (community) edition that can be used for business process modeling and ER modeling.
