Time-critical scheduling in real-time database systems has two components: real-time transaction scheduling,which is related to task scheduling in realtime operating systems, and ...
Studies in [7,8, 91 concluded that for a variety of reasons, optimistic concurrency control appears well-suited to real-time database systems. Especially, they showed that in a re...
Although an optimistic approach has been shown to be better than locking protocols for real-time database systems (RTDBS), it has the problems of unnecessary restarts and heavy re...
