Study On The Intermediate Platform Based On CICS And Implemetation Of Bank-Tobacco System

The development of software has entered the era of architechture.The Software Architecture is a high-level abstract concept of the software and the first decision to make during the development procedure which represents the basic idea of the system design. Through the grasp of the structure and function of the software,it promotes the productivity and reliability effectively and solves the problems in performance.Therefore it has the most profound effect on the whole system.Distributed architechtures have become the main-stream patterns of the application system.This dissertation first discusses the shortage of the two-layer system,then it introduces the three-layer architechture:client+application server+ database server.In the systems of three-layer architechture of the Agricultural Bank, the kernel is the CICS transaction middleware in intermediate course.CICS is the environment supplied by IBM for business which,with the capacity of powerful transaction processing, promotes the reliability, extensibility and security highly because of its advantage in resource integration,cross-flatform applications,and etc.The Intermediate platform of the Agricultural Bank is a CICS-kernel application of three-layer distributed architechture.it integrates management, development, running, maintenance, and etc. The whole system is divided into three parts to response the request of the client:channel access layer, transaction processing layer and data processing layer.Based on the research on the architechture of the Intermediate platform,The Bank-Tobacco System was designed and implemented.
