Sale Ordering System using Centralized Two Phase Locking Algorithm

Abstract

The concurrency control of a distributed system is to ensure that the consistency of the database. The concurrency control mechanism is becoming useful in the ordering system. This paper introduces a concurrency control mechanism for the sale ordering system. Centralized two phase locking is one method of the concurrency control. We use the centralized two phase locking for ordering system because the central lock manager by controlling the all lock information can reduce the additional cost and get the better performance of the system. By using the concurrency control mechanism, the data of the system may be consistent.
