This is a very good question. Much of the value in using entity beans is
the fact that as a developer you need only write the methods to load and
store the bean and the container will manage calling them at the proper
times. Of course there is the caveat that one needs to choose the proper
transaction attributes.
That being said, one ensures the changes are properly stored in the database
by making the changes to the entity bean within a transaction. Given this,
the container will take care of the rest.
