Enterprise Objects Framework Viewed Through Its Classes

As you learned in the previous chapter, Enterprise Objects Framework is divided into layers. This chapter takes a closer look at the responsibilities of each layer. It does so by describing the classes in each layer and demonstrating the roles they play in the four most basic types of Enterprise Objects Framework applications:

Command-line programs without a graphical user interface
Application Kit client/server desktop applications where all the logic is in a client
HTML WebObjects applications where all the logic is in the application server
WebObjects applications with interactive Java clients where the logic is distributed between an application server and its clients
