AgiSim: a simulator for real-time transaction scheduling and concurrency control

Abstract

The design and implementation of Real-Time Database System is a very complicated issue, a simulator for real-time algorithm research and evaluation is helpful. In this paper, we propose a simulator named AgiSim for real-time transaction scheduling and concurrent control, through which researchers can test, simulate and evaluate many real-time transaction scheduling and concurrent control algorithms. AgiSim is composed of transaction generation component, transaction scheduling component and data management component. The simulator is designed with UML, a state diagram and a sequence diagram of real-time transaction scheduling are given. Two mixed transaction schedulers are designed and simulated in AgiSim. © 2012 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).
