The Internet Explorer version 3.0 object model is flat—that is, it has only one level. In this respect it is unlike many other object models. The single-level architecture of the Internet Explorer model makes it significantly easier to master than many other applications. Figure 3-4 shows the complete Internet Explorer object model, and Tables 3-1 and 3-2 describe the object's properties and methods.
