Hi Lars,

Yes, of course it will improve your db when You add PKs (on the ID column of any table) and FKs properly.

There is just one job left for You: You would have to find out what FKs are there... in some cases You could read it out of the column names - if the db goes conform to any naming standards, eg. parent tablesĀ“ ID refers to child tables XYZ_ID or such ...

You could use Oracle Schema Builder for Your purposes, too.

Hope this helps

Jan
