Data integration is a critical problem in our increasingly interconnected but inevitably heterogeneous world. There are numerous data sources available in organizational databases and on public information systems like the World Wide Web. Not surprisingly, the sources often use different vocabularies and different data structures, being created, as they are, by different people, at different times, for different purposes.

The goal of data integration is to provide programmatic and human users with integrated access to multiple, heterogeneous data sources, giving each user the illusion of a single, homogeneous database designed for his or her specific need. The good news is that, in many cases, the data integration process can be automated.

This book is an introduction to the problem of data integration and a rigorous account of one of the leading approaches to solving this problem, viz., the relational logic approach. Relational logic provides a theoretical framework for discussing data integration. Moreover, in many important cases, it provides algorithms for solving the problem in a computationally practical way. In many respects, relational logic does for data integration what relational algebra did for database theory several decades ago. A companion web site provides interactive demonstrations of the algorithms.

About the Author(s)

Michael Genesereth, Stanford University
Michael Genesereth is an associate professor in the Computer Science Department at Stanford University. He received his Sc.B. in Physics from MIT and his Ph.D. in Applied Mathematics from Harvard University. Prof. Genesereth is most known for his work on computational logic and applications of that work in enterprise computing and electronic commerce. His current research interests include data integration and dissemination, enterprise management, and computational law. Prof. Genesereth was program chairman for the 1983 AAAI Conference and the 1997 International World Wide Web Conference. He is one of the founders of Teknowledge, the premier company commercializing Artificial Intelligence; he is a cofounder of CommerceNet, the premier organization for electronic commerce on the Internet; and he is a founder of Mergent Systems, an early vendor of technology for integrated catalogs on the World Wide Web. He is the current director of the Logic Group at Stanford and founder and research director of CodeX (The Stanford Center for Computers and Law).
