SchemaSpy 1.5.1 released

Now displays two versions of the main relationships graph: a smaller 'compact' version and a large full-size version. The compact version should make it easier to get a 'big picture' view of the relationships.

Now takes advantage of the GraphVis dot 2.6 ability to point to the East/West center of a node if running dot 2.6 or higher.

Figured out a way to have the graph point to the appropriate portion of the main table in the table detail pages.... read more

SchemaSpy 1.3.3 released

SchemaSpy now has much better MySQL support with the release of version 1.3.3. This release also has better error reporting when there are problems connecting to a database.

Indexes now include a sort order column and 'records' are now 'rows.'

The relationships counters on the main page no longer include implied relationships, just real foreign key relationships. The main page output is a little cleaner too.... read more

I've finally posted the first release of SchemaSpy. Some sample output is available at http://schemaspy.sourceforge.net/sample . The home page (http://schemaspy.sourceforge.net) needs lots of help. If you have the skills your help would be greatly appreciated.
