Web-Powered Databases edited by David Taniar and Johanna Wenny Rahayu Hershey, PA: Idea Group Publishing, 2003 ISBN: 1059140-092-9 340 350 pages $89.95

The Web is the front end for more and more information access. Consumers now expect print products, like retail catalogs, to be online. Even databases that were previously accessible only through more proprietary methods, such as college course catalogs, are moving to Web interfaces. End users want to search all types of databases online, regardless of the source or variety of the information. This has created big new challenges for Web developers. Providing the most effective and efficient access and maximizing use of computing resources while maintaining integrity and security can be tough. Some experts share their ideas about how to do this in Web-Powered Databases, a collection of research-based articles.

The editors, David Taniar and Johanna Wenny Rahayu, are both computer science researchers and academics from Australia. The book's contributors are professors and researchers from eight different countries, including the U.S., Greece, and Algeria. The editors suggest that Web-Powered Databases will appeal to "individuals who want to enhance their knowledge of issues relating to databases powered by the Internet," such as computer science researchers, students, teachers, e-commerce professionals, and general information technology workers.

Taniar and Rahayu also list some prerequisites for understanding the articles. They assume that readers have "at least a basic knowledge of Internet technology, including Web pages, HTML, scripting and programming, and XML; relational databases, including queries, query language, and query processing; [and] architectures, including heterogeneous architectures and cache and memory management." This is quite a hefty order. I admit that I don't know all of this and was thus unable to fully evaluate all the articles. However, I can give you a summary of the book's structure and content.

Web-Powered Databases is divided into five sections. The first covers querying and mining Web data. One chapter presents X-DEVICE, a combination of XML and the deductive object-oriented database system DEVICE. Another discusses the construction of a domainspecific Web portal through the use of Web mining.

The second section presents several case studies of Web databases that were designed and created by the authors. These include an online tutor payment system, multiple-choice testing system, and product catalog. …
