" ... Web content producers need tools to rapidly and inexpensively build huge data stores and sophisticated applications. This in turn creates a huge demand for database technology that automates the creation, management, searching, and security of web content. Web consumers need tools that can discover and analyze information on the Web.... " The Asilomar Report on Database Research, by Bernstein et. al. Sigmod Record, December 1998.

Subject:
In this course, we will examine the research in the area of data management of web based information, i.e. hyperlinked documents that are spread across a public domain network. We will read and discuss research papers that are related to this area. The subjects that will be covered are (tentatively):

- query languages and systems for Web data, SGML;
- management of Web documents, searching, updating and maintaining Web content;
- finding structure in Web information;
- data integration over the Web;
- warehousing of Web data;
- data-intensive applications on the Web, E-commerce issues;
- transactions on the Web;
