Abstract

The traditional transaction models are not suited to real-time database systems (RTDBSs). Indeed, many current applications managed by these systems necessitate a kind of transactions where some of the ACID2 properties must be ignored or adapted. In this paper, we propose a real-time concurrency control protocol and an adaptation of the Two-Phase Commit Protocol based on the nested transaction model where a nested transaction is viewed as a collection of both essential and non-essential subtransactions: the essential subtransaction has a firm3 deadline, and the non-essential one has a soft4 deadline. We show through simulation results, how our protocol based on this assumption, allows better concurrency between transactions and between subtransactions of the same transaction, enhancing then the success ratio5 and the RTDBS performances, i.e., more transactions may meet their deadlines.
