With the XQuery 1.0 language, database developers finally have a tool that will make it much easier to exchange information between XML and relational data sources. This in- depth tutorial not only walks them through the XQuery specification, but also teaches them how to program with this widely-anticipated language. Whether database developers are coming from SQL, XSLT, or starting from scratch, they will learn about XQuery's support for filtering, sorting, and grouping data, as well as how to use FLWR expressions, XPath, and XQuery tools for extracting and combining information. Readers will discover how to apply all of these tools to a wide variety of data sources, and how to recombine information from multiple sources into a single final output result. "XQuery" also delves into critical advanced issues such as data typing and designing efficient query logic.
