Nope - it's a normal database you have simply done a query against the database - the result of SELECT and then return to the database to validate your data against it - think about it; your insurance company posts you a claim form and you then send it back in - you need to validate what's on the form (our equiv of time table) against the database.

Also, please can you show me how you would simply put history in the table with celko's example.
