Business Patterns

In this chapter, we will cover definitions of the Business Delegate pattern, the Session Fa?ade pattern, and the business-object pattern. We will show the reasons to use these design patterns, common approaches to each of them, their interaction with other patterns, their evolution, and how they behave in the real world. We will also demonstrate some examples of these patterns' implementations.
