The use of service-oriented technologies has been used increasingly to speed up the application process and respond to changing business needs for many e-commerce systems. However, current e-commerce transaction services are poor at processing data access conflicts in a timely manner. The different timely data access for e-commerce applications should be considered with concurrency control mechanisms. In this paper, we study the concurrency control problem among interleaved web service transactions under differentiated real-time demands. We propose a new method called two-phase locking with fairness principles (2PL-FP), which resolves the concurrent data access for both real-time and non-real-time support operations. The design issue aims to meet the deadline requirements of real-time transactions and minimize the response time of non-real-time transactions in the web service and service-oriented computing environment. Simulation results show that our method can achieve a significant performance improvement compared to current approaches.
