Data Model Diagrams

The Entity Relationship (ER) diagram of a database describes graphically the attributes (columns) of the tables as well as the relationships between the tables. It is a valuable reference when querying a database.  Download the latest version of the QDB ER diagrams today.

These documents have been prepared in the Adobe Acrobat (PDF) format for easy viewing and printing. If you do not already have a PDF reader, you can download one from Adobe's website.
If you have any questions, please contact the QDB Team at support@qdb.ucla.edu. We will be glad to help you.
