In this chapter, we'll be looking at how to perform basic import and export of data, and we'll discuss some of the other things possible with tools like Integration Services. We will place our primary focus on the basics of SSIS packages, setting us up for a more advanced discussion of SSIS programmability in the Web-based chapter, Chapter 25.
Understanding the Problem
