Abstract

The Toronto XML Server (ToX) is a repository manager for XML data and metadata. Users register documents that ToX may store in one of several different back-ends, including the file system, an ODBC-compliant relational database, or ToXin, our own XML indexing scheme. XQuery core queries can be applied to a document or to a collection of documents, possibly across heterogeneous back-ends. We will describe the architecture of the system and the implementation of the main components. We will present a pilot application, currently under development, to support an experiment in evidence-based medicine at a local hospital by serving XML to a front end running on handheld devices.

He has been a visiting scientist at the IBM Centre for Advanced Studies, AT&T Bell Laboratories, NTT Basic Research Labs in Musashino, Japan, and the IASI in Rome. His research interests are in databases and knowledge-bases including database design theory, query languages, database visualization, query processing, belief revision and knowledge-base update, and global information systems. He led the Hy+ visualization project for graph databases, including its applications to the exploration of large software systems, debugging of parallel programs, and network management. His most recent research deals with the design, analysis, and implementation of query languages for the World Wide Web. Alberto has been Associate and Acting Chair of the Computer Systems Research Institute and chaired or co-chaired the Program Committees of the ACM Principles of Database Systems Symposium (1991), International Conference on Very Large Databases
(1992), and International Symposium on Deductive and Object-Oriented Databases (1995), as well as General Chair of the ACM Principles of Database Symposium for 1997 and 1998.
