The course also covers XML serialization according to XML Schema and the tight coupling between XML and ADO. It includes a practical discussion of performance tradeoffs for various XML technology alternatives.

Like many other Internet standards, the DOM is an official standard of the World Wide Web Consortium, better known as the W3C. In its simplest form, the DOM defines an XML document as consisting as a tree of nodes. On the other hand, the node tree doesn't include XML attributes, though you can retrieve them from the parent elements.
The root element in the XML file becomes the root node of the tree, and other elements become child nodes. However, the DOM and the Xml Text Reader are flexible enough that you can customize their work as you like.

December 4, 2002 Priya Lakshminarayanan Despite the many articles explaining W3C XML Schema (WXS), it's not enough to discuss WXS as a specification only. SOM is a rich API which allows developers to create, edit, and validate schemas programmatically -- one of the few such tools available so far.
Educational materials should also discuss tools which aid the development of XML applications which employ WXS. SOM operates on schema documents analogously to the way DOM operates on XML documents.
Numerous programming examples and exercises are provided, including a fully-developed case study.
Participants will receive a comprehensive set of materials, including detailed course notes and soft copy of all the programming examples and lab exercises.
Schema documents are valid XML files that, once loaded into the SOM, convey meaning about the structure and validity of other XML documents which conform to the schema.
SOM is indispensable for a certain class of application, like a schema editor, where it needs to construct the schema in memory and check the schema's validity according to the WXS specification. The following is a simple customer schema, with a top-level Customer element that has two child elements, First Name and Last Name, and one attribute, Cust ID.
