- Thurs, 13-Oct-2011 4:45pm - 6pm DBGroup Seminar - Query Optimization Over Web Services
Presented by: Sara Sutton & Sireesha Gurrala
Thompson Library Room 322
Abstract: Web services have become popular for sharing data among heterogeneous systems.
WSMS is a system that enables users to query over multiple web services in a transparent
and integrated fashion. The queries considered are select, project and join.
Topics covered are the bottleneck cost metric, pipelined parallelism,
(i.e. arranging the web services in a pipelined fashion), the selectivities of web services,
ordering of web services with and without precedence constraints
and discussion of the algorithm to determine optimal chunk size.
