XML Schema, XML DTD and ODL – A Comparative Study

Abstract

Extensible Markup Language (XML) is an extensible and universal format for structured documents and data on the Web. Derived from SGML (Standard Generalized Markup Language), XML was initially developed in 1996, and became W3C’s standard in 1998. XML provides the abilities to handle an incredibly wide variety of information, and allows such information to be self-describing. With its powerful expressiveness and flexibility, XML promised to add structure data on the Internet, bringing the Web one step closer to realizing the potential for universal communication with anyone, anywhere.

The thesis reviews the basic concepts of XML, XML related tools and products. Using an account management application as a benchmark, XML’s data modeling constructs are evaluated and compared with those of Object Definition Language (ODL). Finally, the design and implementation of a mapping tool which transforms an ODL Schema to an XML Schema is discussed.
