In this chapter, we covered that enterprise applications are the applications which provide solutions to enterprises. These applications consist of huge code. To increase maintainability, performance, and testability, such applications will be developed in tiers. These tiers consist of logical separation of code using layers. Though each layer provides specific functionalities, they have been divided into separate modules. These modules will be developed by a team of developers. To establish coordination, easy sharing and maintaining the history of the files will be done using a versioning tool.
In the next chapter, we will be covering the basics of web applications and developing a sample application using JSP and Servlet. Also, we will be covering the basics of developing a Spring MVC application.
