Developing Rich Domain Models

Object-oriented design (OOD) is good way to tackle the complexity of modern applications. Yet many complex, enterprise Java applications are written in a procedural style. One reason is because EJB2 created too many obstacles to using object-oriented design techniques. Fortunately, enterprise Java technologies have improved. Plain Object Java Objects (POJOs) and object/relational mapping frameworks such as Hibernate, JDO and EJB3 led to the revival of OOD.

In this presentation, you will learn how to implement business logic using a rich POJO domain model. We will compare and contrast a procedural design with an object-oriented design and describe the benefits of OOD. You will learn how non-invasive frameworks provide dependency injection and persistence for a domain model.
