On using similarity for concurrency control in real-time database systems
Most of the proposed concurrency control protocols for real-time database systems (RTDBS) are based on serializability theorem. Owing to the unique characteristics of real-time da...

Applying Update Streams in a Soft Real-Time Database System
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...

Triggered Real-Time Databases with Consistency Constraints
Real-time database systems incorporate the notion of a deadline into the database system model. USUally, deadlines are associated with transactions, and the system attempts to exe...

Using Dynamic Adjustment of Serialization Order for Real-Time Database Systems
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...
