1. 1 Database Research at the UW  Faculty: Alon Halevy and Dan Suciu. A dozen Ph.D students  Related faculty: Oren Etzioni, Pedro Domingos, Dan Weld and Henry Kautz.  Focus:  Integration of data from multiple autonomous data sources.  Efficient processing of XML data.  Producing results of queries as web sites or other flexible presentations -- that is, flexible construction of data-intensive / adaptive web sites.  Data management for ubiquitous computing.  Model management tools (in collaboration with P. Bernstein).  Machine Learning techniques for data mining.

2. 2 Query Processing for Data Integration  Query across multiple network-bound sources  Autonomous data, subject to update (Tukwila interleaves planning and execution)

3. 3 Query Processing for XML  XML: emerging standard for sharing data.  XML-QL: invented by Suciu and Halevy. Basis for W3C working group on standard query language.  Xmill: [Suciu, 2000]: compressing XML data. Best paper award at SIGMOD-2000.  Processing streaming XML data: the Tukwila System (Ives, Halevy, Weld).  Interfacing XML with relational databases.

4. 4 XML: the Data Format for Information Exchange

5. 5 Sagres: Data Management for Ubiquitous Computing  Key: view devices as data sources that can answer queries and have effects on the world

6. 6 Sagres Architecture
