The integration phase of real-time COTS-based systems is often problematic because when multiple tasks run concurrently, the interference at the bus level between cache fetching a...
Many papers have examined how to e ciently export a materialized view but to our knowledge none have studied how to e ciently import one. To import a view, i.e., to install a stre...
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...
