From Joins to Aggregates and Optimization Problems
The course introduces recent development on solving a host of computational problems in the database. The unifying theme underlying this development is the use of the structure of the problem to avoid redundancy in data representation and computation.Read More..
Research Projects ( 26-minute video overview )
We investigate trade-offs in static and dynamic evaluation of queries with arbitrary free variables. In the static setting, the trade-off is between the time to partially compute the query result and the delay needed to enumerate its tuples. In the dynamic setting, we additionally consider the time needed to update the query result under single-tuple inserts or deletes to the database.Read More..
