In this chapter you will round out your coverage of data technologies by looking at how you can implement XML web services that both expose and consume data. The move to use XML documents both as the source and the client storage of data means that you need to look at how you can create an XML document from an existing DataSet and directly from Microsoft SQL Server. This chapter focuses mainly on the theory of and SQL. Exercises are included to show the code and techniques needed to understand the questions on the exam.
