Oracle adds data modeler viewer to SQL Developer

Oracle has launched release 2.1 of Oracle SQL Developer, its free database development and migration tool.

The new release adds PL/SQL unit testing capabilities, enabling developers to build and share testing suites runnable from command line interfaces and in batch mode.
It also includes a new data modeler viewer, capable of browsing data models built from Oracle's standalone Data Modeler in read-only mode.
The product is available for all versions of Oracle Database 11g, Oracle Database 10g and Oracle9i Database Release 2. It runs on Windows, Linux or Mac OS X.
