To answer your first question, I'd say that you should leave any checking logic out of your DAOs.
For clarity, a DAO is where you do your DB querying; it returns Transfer Objects (TOs) as results, and accepts TOs as input for narrowing searches. They usually represent an object that you want stored or retrieved from the database. Your TOs should have setters and getters, and even should have zero logic unless you put it in the setters. If you try to put a 50 character string into a TO where the DB expects only 6 characters (for example), the TO should throw an exception or error out in some way. If its not a getter or a setter, it doesn't belong in the TO, and if you have logic that checks the input data for correctness it belongs in the TOs setter. (That's how I do it in Java, anyway.) I don't have any experience with FDS, but you should give it a shot. Its free for a single box with up to 100 users, but if you ever outgrow that you'll need some real money on hand. The prices have been mentioned on the list many times. -- jeremiah(); Briggs, Christian M wrote: > Hi Steven, > > Thanks for the tip.
