One of Java’s main strengths is that it is mature enough that most common scenarios have their own library, saving you the time and effort of writing and rewriting the functionality from scratch every time. This part focuses on common libraries and application frameworks to help you produce professional, robust applications capable of communicating with the outside world, whether that is by producing a server that displays web pages, or an application that is used to persist information to a database.

Chapter 12 covers databases, introducing the concept of a database store and how Java can interact with the database.
