I was trying to replicate the jubula db by using rubyrep, but it is neccesary that all the tables in the database have a primary key.
Rubyrep allows you to exclude some tables, that's why I would like to know if there are some tables that jubula use just for project info that won't be updated when you create test case, test suites or others?
I spoke to the team: We use an OR-Mapper (EclipseLink) which deals with setting constraints. Because of that, we don't know what would happen if parts of the scheme were left out. So the gist is that we reeeaaally don't recommend it.
