ABSTRACT:
A method for localizing execution of subqueries and determining collocation of execution of subqueries in a shared-nothing database. The concept of compatible partitioning is used to localize database operations in order to eliminate excess processes and communication, and thereby improve response time and throughput for the database management system. The method reduces the number of process by reducing the number of nodes involved in processing a query and by combining multiple processes.
