Summary
What We'll Learn in This Chapter
Why we need a class-type architecture, and more to the point, why we need a five-layer class-type architecture.
The implications of the architecture for both system development and for project management.
What each layer is really all about and how it fits in with the other layers.
Users want systems that are better, faster, and cheaper. Not only do they want new systems that conform to these requirements, they also want systems that are adaptable and modifiable. You might get lucky and get new requirements that are easy to meet, but I wouldn't want to count on it. Without a well-thought-out architecture in place you will probably not be able to develop applications in a timely and efficient manner that meet the demands of your users.
The class-type architecture presented in this chapter meets these goals.
As an object-oriented developer you need to have an overall game plan as to how you intend to design your system. The class-type architecture described in this chapter provides you with an excellent strategy for organizing the classes of your application to increase both its extensibility and maintainability. I don't claim that this architecture is detailed enough for the needs of your organization. I do claim, however, that it does provide an approach to partitioning your applications that leads to a significantly better design.
