As I understand it database synchronization happens at the transaction
boundaries. The bean is synchronized with the database at the start of a
transaction and the database is synchronized with the bean at the end of a
transaction. If you call a entity bean method that is declared as REQUIRES a
transaction then the database will be updated at the end of the method call.
So, each call to setter method will result in a database write. My
explaination ignores nested method calls from another ejb with an inherited
transaction context.
I think that whether the database is updated at other times may be vendor
dependent.
