In this chapter we have, with examples, presented and analyzed the improvements
provided by two APIs whose major objective is to facilitate interaction with your data
base. The first presented was JPA API, which gives you the ability to create, read,
update, and delete data from a database by using Java objects. The second was JTA
API, which is an API designed for transparent management of transactions in one or
more data sources.
In the next chapter, we'll talk about EJB s and we will make a small example, which
will consist of putting together most of the APIs that we have studied.
