The Concurrency Control of Real-time Distributed Web Applications based on J2EE Multi-tier Architecture

摘要

In this paper we presented strategy and method to design and analyze resource-oriented concurrency control in the Web application systems, so as to improve the correctness and performance of concurrent systems through resource-oriented interface programming. The approach mainly contain three steps: firstly, business extraction is implemented to provide the resource for concurrency control;secondly, the resources that related to the business process need to be classified and registered, so as to be recognized by the control system;thirdly, a dynamic link between the registered resource and strategy warehouse should be established, then the concurrent resource and concurrency mechanism can be connected together to solve the conflict in using the resources between different users.
