Data on the Web

Data on the Web is the only comprehensive, up-to-date examination of these rapidly evolving retrieval and processing strategies, which are of critical importance for almost all Web- and data-intensive enterprises. This book offers detailed solutions to a wide range of practical problems while equipping you with a keen understanding of the fundamental issues—including data models, query languages, and schemas—involved in their design, implementation, and optimization. You'll find it to be compelling reading, whether your interest is that of a practitioner involved in a database-driven Web enterprise or a researcher in computer science or related field.

Features :

• Provides an in-depth look at XML and other technologies for publishing structured documents on the Web.
  
• Examines recently developed methods for querying and updating structured Web documents and semistructured data, including XML-QL and XSL.
  
• Looks deeper into the convergence of Web and database approaches to semistructured data presentation and querying.
  
• Details practical examples of how these techniques are already being applied—and how they will be used in the near future.
  
• Teaches sound techniques for writing queries over Web data, describing loose schemas over partially structured data, and implementing and optimizing queries on semistructured data.
