XML is growing in usage every day. Some relational purists will look at XML and shake their heads. However, XML is complementary to relational technologies. In fact, a lot of XML is structured just like relational data. Is that good? Probably not, since the two models are best at their intended data formats: XML for semistructured data, and relational databases for relational data. Plus, the semantics of storing, querying, and modifying XML is what confuses most relational people. As you’ll see, the XML query language, XQuery, looks nothing like Transact-SQL (T-SQL). However, you can use the two technologies together to solve your business problems.
