Transaction Processing in Mobile Distributed Real-Time Database Systems
In a real-time database system RTDBS, transactions have to be completed before their deadlines and all the accessed temporal data objects have to be valid. Besides meeting these timing constraints, a RTDBS needs to observe data consistency constraints as well 44. Diierent transactions scheduling algorithms and concurrency control protocols have been proposed to satisfy these constraints 44. The...

متن کاملReal-Time Transaction Scheduling in Database Systems
A database system supporting a real-time application, which can be calledà real-time database system (RTDBS)', has to provide real-time information to the executing transactions. Each RTDB transaction is associated with a timing constraint, usually in the form of a deadline. EEcient resource scheduling algorithms and concurrency control protocols are required to schedule the transactions so as ...
متن کاملCommit processing in distributed real-time database systems
Incorporating distributed data into the real-time framework incurs the well-known additional complexities that are associated with transaction concurrency control and database recovery in distributed database systems. We investigate here the performance implications of supporting transaction atomicity in a distributed real-time database system. Using a detailed simulation model of a rm-deadline...
