This week's book giveaway is in the OCMJEA forum. We're giving away four copies of OCM Java EE 6 Enterprise Architect Exam Guide and have Paul Allen & Joseph Bambara on-line! See this thread for details.
So I've been thinking a bit lately about mvc. 'v' seems to be covered in jsp/velocity/taglibs
'c' is covered by struts et al. (and yah, struts does a bit of 'v' and 'm' as well).
But what about pure 'm'?
What about a data-abstraction layer of some sort.
I've always thought Torque was a cool-looking framework. I can't say that I've ever tried it though. But perhaps someone more experienced could read the tutorial and/or docs (as I've done) and weigh in with an opinion. Or better yet, a torque user.
The one aspect of this framework that is a bit cumbersome (among others) is that it can't connect to a database and use metadata to generate classes. You'd have to specify your database metadata separately in the *-schema.xml files. (detailed in Tutorial Step 2 )
One thing I did like though was their idea of peer classes, where if you had 'custom' code, then changes to the database and subsequent regeneration of your classes would not blow away your custom stuff. Peers How-to
I'm not sure about their choice for OR mapping, as put forward here: O-R Mapping
Though I'm certainly no expert, so maybe this is the best way. But it seemed to me to be sacrificing 'normal form' tables for the ease of Torque authors. (Would i ever be able to use those tables outside of torque? would i *want* to? will my DBA laugh me out of the room?)
Finally.. what makes me want to steer away from frameworks like this is the sort of thing you see at the very bottom of the peers-how-to page linked earlier... The code to produce that 'complex' query seems more complex to me, than just the SQL.
Ok.. I'm not sure if there is really a question in all of that, but I'd like to hear opinions on this framework. [ April 21, 2003: Message edited by: Mike Curwen ]
