We explore the execution of queries with client-site userdefined functions (UDFs). Many UDFs can only be executed at the client site, for reasons of scalability, security, confide...
Well-designed indices can dramatically improve query performance. Including query workload information can produce indices that yield better overall throughput while balancing the...
In this paper we propose a data model for representing moving objects with uncertain positions in database systems. It is called the Moving Objects Spatio-Temporal (MOST) data mod...
