Automatic Mapping of XML Documents into Relational Database: Introduction
Abstract
Extensible Markup Language (XML) nowadays is one of the most important standard media used for exchanging and representing data through the Internet. Storing, updating, and retrieving the huge amount of web services data such as XML is an attractive area of research for researchers and database vendors. In this chapter, the authors propose and develop a new mapping model, called MAXDOR, for storing, rebuilding, updating, and querying XML documents using a relational database without making use of any XML schemas in the mapping process. The model addressed the problem of solving the structural hole between ordered hierarchical XML and unordered tabular relational database to enable us to use relational database systems for storing, updating, and querying XML data. A multiple link list is used to maintain XML document structure, manage the process of updating document contents, and retrieve document contents efficiently. Experiments are done to evaluate MAXDOR model. MAXDOR will be compared with other well-known models available in the literature (Tatarinov et al., 2002) and (Torsten et al., 2004) using total expected value of rebuilding XML document execution time and insertion of token execution time.
