Database Research Group
The Database Group at the University of Waterloo is one of the largest such
groups. The group's research is broad-based addressing both extending and
enhancing database management systems (DBMS), and data management for new domains.
The research focuses on data management issues as they apply to complex objects,
geometric and spatial data, video and audio data, historical data, structured
documents and text, and real-time data as well as to traditional relational
database systems. This wide coverage mirrors the expanding role of database
systems in managing very large amounts of diverse data. The research also has
wide coverage of many aspects of database system functionality. Consequently,
there are ongoing projects that explore storage structures, indexing methods,
query languages and optimizers, transaction management, and distributed data
These Web pages and the following two documents prepared for an internal review in 2005 give more information about the group's activities (note that they are up-to-date only to 2005):

- Lukasz Golab was awarded
one of ten Bell Canada 125th Anniversary Scholarships at a ceremony at the
Bell University Laboratory Symposium on November 8th. Lukasz's research focuses
on a new type of database: a data stream management system (DSMS). DSMSs
are used for processing streams of live data, such as Internet packet traces,
stock price tickers, and sensor measurements. The fundamental problem that
he is addressing in his thesis is query processing over sliding windows of
recently collected stream data. More information about the scholarship is
available from a Bell press release. (24-Nov-05)
