Designing a Component-based Application
Now that we've covered the basics of business objects, we're going to design a simple component-based application that implements business objects. First, we'll create business object and data access base classes from which we can derive all of our application-specific business objects. After that, we'll take some "already built" use cases for a simple library application, and create business objects that implement the use cases. During this process you'll see how thinking about data early on can help to prove and solidify your object model.
