Abstract

With the diversification of users and systems requirements, the integration of control and information systems has become more and more important. In these systems, assurance is required to achieve high performance of real-time control and high reliability of the transaction process. However, in high load transaction conditions, it is difficult for conventional centralized systems to achieve data consistency during real-time processing. In this paper, "Autonomous Decentralized Multi-layered Data Consistency Technology (ADMLDCT)" is proposed, which is based on heterogeneous "Data Fields (DFs)" with different process times of data consistence. The consistent data and inconsistent data coexist in the system. In this technology, each layer autonomously makes data consistent and cooperates with other layers according to the different stay time of data. As a result, both the recovery of inconsistent data and congestion of each layer can be improved. These technologies have been applied to the IC (Integrated Circuit) Card ticket system of East Japan Railway Company, where the effectiveness of the technology has been proved.
