Well I'm not sure what kind of Java applications you write but in the world I inhabit the client request "we just want to add one more field to this form" is guaranteed to send a shiver down the spine as it's usually followed by "How much?, for adding a single field? you gotta be kidding". To add a single persisted field to an input form requires the modification of most if not all of the layers of an application. Adding a single field to a product line for example would probably require the modification of all the CRUD methods for that line, not to mention the inclusion of the field in the search algorithms, modifying the validation layer, incorporating the field in a logical place in the HCI, modifying and refactoring the relevant code etc etc. Anything that can reduce the amount of work required to implement such an apparently trivial change has got to be a good idea. Having said that, I don't used ORMs myself, I mean I've tried, I've really tried but I start reading the documentation and my eyes glaze over and I discover that I need to learn 'another' (query) language and I decide that it's just not worth the effort. Stick to SQL, accept the overhead and I don't think you can go far wrong. Just my 2 euros worth -------------------------- I find myself actually agreeing with you again. Adding even a single field to the underlying data structures is *not* straightforward at all in a typical Java application. I also tend to agree with your comment regarding ORMs v. standard SQL. -- And loving it, -Qu0ll (Rare, not extinct) _________________________________________________ Qu0llSixFour@gmail.com [Replace the "SixFour" with numbers to email me]
