Database performance is an important aspect of database usability. Distributed real time database systems (DRTDBS) must be designed on all levels of database architecture to support timely execution of requests. The primary performance objective in DRTDBS is to minimize the number of missed deadlines. Due to the demanding nature of this objective, traditional approaches are inadequate. However, the research in DRTDBS has been mostly devoted to extending traditional transaction processing techniques to solve the issues important for the design of DRTDBS. In this environment, new policies/protocols must be designed to efficiently handle the transactions execution. Our works involves design of new priority assignment policies and commit protocols and comparison of their performances with existing policies/protocols.
