## The Understand for Java Project Database

The Understand for Java project database is stored in a proprietary binary format. The file format uses a network/object format that is optimized for storing Understand for Java information.

Understand for Java databases have a file extension of .udj.

The project file permits multiple simultaneous read accesses, but it does not (yet) support multi-user write access.

Occasionally, adding a new feature to Understand for Java requires a change to the database format. Such changes are noted in the Change Log. After you install a build that modifies the database format, existing projects are automatically reparsed when you open them in Understand for Java.
