Abstract

Concurrency control based on conventional techniques requires additional efforts for deadlock detection and elimination. The possibility of a deadlock is also connected to the introduction of delays, and repeated restarts of transactions in deadlock cycles. In the proposed approach, a technique for generation of data flow precedence graphs among transactions at data sites has been studied. The local access graph approach is a fully distributed approach. Through local computations, the approach can prevent deadlocks in a distributed system.
