Presentation Transcript

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

  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. XML: the Data Format for Information Exchange

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

  6. Sagres Architecture
