Part 8 Web and DBMSs
Part 8 of the book deals with the integration of the DBMS into the Web environment,
semistructured data and its relationship to XML, XML query languages, and mapping
XML to databases.
Chapter 29 examines the integration of the DBMS into the Web environment. After
providing a brief introduction to Internet and Web technology, the chapter examines
the appropriateness of the Web as a database application platform and discusses the
advantages and disadvantages of this approach. It then considers a number of the different
approaches to integrating DBMSs into the Web environment, including scripting languages,
CGI, server extensions, Java, ADO and ADO.NET, and Oracle’s Internet Platform.
Chapter 30 examines semistructured data and then discusses XML and how XML is an
emerging standard for data representation and interchange on the Web. The chapter then
discusses XML-related technologies such as namespaces, XSL, XPath, XPointer, XLink,
SOAP, WSDL, and UDDI. It also examines how XML Schema can be used to define the
content model of an XML document and how the Resource Description Framework (RDF)
provides a framework for the exchange of metadata. The chapter examines query languages
for XML and, in particular, concentrates on XQuery, as proposed by W3C. It also
examines the extensions added to SQL:2003 to enable the publication of XML and more
generally mapping and storing XML in databases.
