Database System Concepts 6th Ed., by Silberschatz, Korth and Sudarshan, released Jan 2010.
Publications (My entry in the DBLP bibliography, and my profile in Google Scholar)

Query processing and optimization.

Holistic optimization spanning the programming language/SQL boundary, including optimization of nested iteration, and iterative invocation of queries by creating batched bindings and asynchronous query invocation. This work spans the boundaries of programming language static analysis and database query optimization. (For details look here.)
Multiquery optimization and Parametric query optimization (for details look here)
Testing database applications, including test data generation to ensure correctness of queries, and checking for serializablity of applications running under weak levels of consistency. For more details, look here
Keyword querying in databases Soumen Chakrabarti and I lead the BANKS project, which aims at supporting keyword queries on relational and XML databases.
Earlier areas included and Main Memory Databases (I was one of the founders of the DataBlitz main memory database project in Bell Laboratories, Murray Hill). I also worked on failure recovery error checking and fault tolerance issues, particularly in main memory databases.
