you're in full control of your object model and database design,
Hibernate is a good choice of O/R tool.If you are accessing any 3rd
party databases (e.g. vendor supplied), or you're working with a legacy
database, or even just a really poorly designed database, then an O/R
mapper might not be capable of handling the situation. That's were an
SQL Mapper comes in handy
