He was a designer and an implementor of the R* distributed DBMS, the Starburst extensible DBMS and DB2. His algorithms have been implemented in several IBM and non-IBM products, and university prototypes. He is the primary inventor of the ARIES family of recovery and locking methods, and the industry-standard Presumed Abort commit protocol. His research interests include concurrency control, recovery, commit protocols, index management, semi-structured data management, query optimization, active databases, OODBMSs, workflow, and distributed systems. He was the Americas Program Chair for the 1996 International Conference on Very Large Data Bases, the Program Chair of the 1987 International Workshop on High Performance Transaction Systems, and a Program Vice-Chair of the 1994 International Conference on Data Engineering. He is an editor of the VLDB Journal, and Distributed and Parallel Databases - An International Journal.

Recent progress in data integration

In the last few years there has been considerable interest in the problem of providing access to large collections of distributed
heterogeneous information sources (e.g., sources on the World-Wide Web, company-wide databases). This interest has spawned a significant amount of research in Database Systems and related fields (e.g., Artificial Intelligence, Operating Systems, Human Computer Interaction). This has led to the development of several research prototypes for information integration and recently, we are seeing the beginnings of an industry addressing this problem.

The goal of this tutorial is to survey the work on information integration, to illustrate the common principles underlying this body
of work, to assess the state of the art, and identify the open research problems in this area. The tutorial will illustrate the issues
involved in information integration through several implemented systems.

Managing Multimedia Information in a Database Environment

We discuss multimedia information management from the point of view of database systems: how the various aspects of database design and the modules of a database system have evolved over the years to better manage multimedia information. We start by examining the nature of multimedia data and the area of multimedia data modeling. We then discuss how multimedia data has influenced the evolution of the various modules of a standard database system; specifically, those having to do with query processing, choice of access methods, query optimization, transaction management, buffer management, storage management, recovery, and security. Finally, we consider the various commercial systems that have recently appeared which manage multimedia information.
