[SLUG] J2EE

[Stephen O'Neill]

This is a question for those that have experience of programming with 
J2EE...

I'm kinda mimicking the J2EE system for modelling database entities.

Very broadly speaking, when the entity dies it is written back to the 
database.

What I want to know is does it do that for all entities irrespective of 
whether their properties have changed or not... and if it holds some 
sort of modified state does a setProperty() method automatically cause 
it to get written back, or does it just do it if the new value is 
somehow different?

I suspect that I'll have to play to sate my curiosity, or expect to be 
lectured on how I've misunderstood the whole concept.

The reason I'm asking is that I've saved a ridiculous number of queries 
by holding modified state, and wondered how granular to make it.

Steve
