Real-Time Databases: MDDS Systems
University of Massachusetts, Amherst

The Real-Time Database Systems Laboratory is part of the Computer Science Department at the University of Massachusetts. Our current research and current results focus on integrating active, real-time, temporal and multimedia databases for crisis management in Massive Digital Data Systems (MDDS). This work is funded by the Advanced Research and Development Committee of the Community Management Staff.

Real-Time Concurrency and Recovery Algorithm Testbed (retired)

Real-Time Concurrency and Recovery Algorithm Testbed (RTCARAT) was the first physical testbed for real-time databases. It contained all the major functional components of a transaction processing system, including real-time concurrency control, transaction scheduling, etc. Experiments were conducted focusing on real-time transaction processing. Ideas developed here were extended and formed the basis for RADEx (see below).

Real-Time Active Database Experimental Simulator

Real-Time Active Database Experimental Simulator (RADEx) is the first real-time, active, object-oriented, temporal database simulator. It is being used to study

Priority assignment and real-time transaction scheduling in active real-time databases
Real-time logging and recovery
Consistency and scheduling in temporal databases
Multimedia databases
