With an understanding of COM firmly in place, we can turn our attention to the specific services that are used to build a distributed application. Almost every distributed application produces or accesses stored data, so we'll start by looking at the Microsoft Data Access Components (MDAC).
As with the other chapters in Part One, the intent here is not to give you all the information you need to become a database guru. Instead, this chapter focuses on the concepts you need to understand to successfully write a Microsoft Windows Distributed interNet Applications (DNA) application. If you are interested in learning more about databases and data modeling, please refer to the bibliography.
