Chapter 1: Introducing Business Objects

Overview

In the introduction, I presented the rationale for this book, which is that object-oriented design, business objects, and Visual Basic 5 allow us to develop highly scalable and reusable code. In this first chapter, we'll look at these concepts and the arguments for them in more detail. Specifically, we'll review:

• Defining objects
  
  
• Defining business objects
  
  
• Using Visual Basic 5.0 to create objects
  
  
• Re-using code with components
  
  
• Business objects in action - application types
  
  
• Object-oriented principles in Visual Basic 5.0
