What Does Enterprise Objects Do?

Enterprise Objects is a complex system that does much more than just communicate with data sources. It also includes objects that participate in user interface-to-data source synchronization, it helps you build business logic into Java objects, and it provides an object-oriented framework with which you develop data-driven Web and desktop applications. Enterprise Objects does the following:

• manages transactions for JDBC, JNDI, and other types of data sources

• maps database contents to Java objects

• allows you to focus on writing business logic rather than on writing SQL to talk to a data store

• helps you build object-oriented database applications

• helps you to maintain platform independence while providing the flexibility to take advantage of platform-specific features

• lets you build robust database applications that respect the Model-View-Controller paradigm and object-oriented design principles

• provides a distribution layer between client and server in Java client desktop applications

• provides objects that allow heterogeneous user interface kits to communicate with Java business objects

• provides a change tracking mechanism, as well as automatic undo and redo

“Figure 2-1” gives a high-level view of the core layers of Enterprise Objects.
