Real-Time Database Systems Lab
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).
