Chapter 8 -- Designing the Main Business Tier

[Previous] [Next]

Chapter 8

The main business tier has two parts:

• A business interface part, which we'll cover in the next chapter
• A business object part, which we'll cover in this chapter

Before we begin to design either part, we had better see whether the facade and GUI developers have come up with anything new. If they have, we'll probably need to reengineer the facade classes of our project to synchronize the Rational Rose model with these changes.
