Summary
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 EJBs and we will make a small example, which will consist of putting together most of the APIs that we have studied.
