In this chapter, we discussed OOP and its three main features: inheritance, encapsulation, and polymorphism. Using these features, the classes within an application can be abstracted to provide definitions that are both easy to understand and protected against being used in a manner that is inconsistent with its purpose. This is an essential difference between OOP and some earlier types of software development language such as structural and procedural programming. With the ability to abstract functionality, the ability to reuse and maintain code is increased.
In the next chapter, we will discuss various patterns used in enterprise software development. We will cover programming patterns as well as software development principles and patterns used in the Software Development Life Cycle (SDLC).
