Extend the project defintition
Source Control for Oracle could also become apart of the deployment project. This way you would like to have connections towards different databases in the same project. For instance I would like to have a connection towards development, test, qa and maybe even production for the same project. This way I could develop, pull changes to svn, push changes to test, then to QA, and at last to production.
It could also be very handy to be able to change the SVN (or have several SVN connections) for instance to a tag (release) library.
Then you could easily rollback to old realease.
