EJB would give you new level of portability problems :) Especialy ejb 2.x with EJB QL... > >I would model my domain data, use hibernate as > >persistence layer, (maybe ) create SLSB for > accessing > >hibernated datastore ( depends on your architecture > ) > > Did that, but still don't see a way to avoid monthly > transaction > tables. Suggestions? You can model your domain data in a way, that no relation goes out of transaction ( say transaction knows nothing about accounts, or whatever is in your domain ) And then you have object "month", which has collection of transactions. And this collection happens to select only those which belong to certain month. ( either date based, or with ID of month ) Then you can archive your transactions away without breaking relations. > >If you to this clever, you will end with a > transaction > >log which can be safely archived / truncated. > > Could you explain.

Then hibernate is your choice. YOu have your java beans and mapping files. And you can forget about database. And it has couple of cool features, and is really fast... regards, ===== ----[ Konstantin Pribluda ( ko5tik ) ]---------------- Zu Verst�rkung meines Teams suche ich ab Sofort einen Softwareentwickler[In] f�r die Festanstellung.
