Examples – Table of Contents
The following examples show you how you can use DataDirect XQuery to work with data in a MySQL relational database. Consider the following scenario: Your company receives book orders from a variety of partner companies; when an order is received, an XML document consistent with a "canonicalq internal XML Schema (structure) must be created so that it can be sent to the warehouse to fulfill the order. Orders are usually submitted in a proprietary XML format; but in some cases orders are not even in XML format; nor is the information contained in these orders a subset of what the "canonical" internal format requires. Once fulfilled, orders also need to be archived in the company’s main database for archiving/reporting purposes. Your company relies on a MySQL database to store information about all the books in inventory, and to keep track of the orders.
As you'll see, XQuery, and in particular the DataDirect XQuery implementation, provide a great way to solve this and similar problems.
