Research & Development Of Comprehensive Front-banking System

In resent years, kinds of newly-developed banking businesses, including middle agent business, card business, etc., have been developed rapidly. But the current banking architecture is becoming increasingly disordered due to lack of uniform plan. Such situation results in complicated banking network, low dealing efficiency, hard maintenance and bad system scalability. Now, banking core business mainframe is surrounded with more and more front-banking machines. On the basis of profound analysis for the present situation and requirement of bank, this thesis puts forward a total resolution scheme on comprehensive front-banking system.This thesis has focused on research and development in back core system which is divided into two sub-systems. One is named by channel sub-system, which is represented for receiving and sending of trade. In this sub-system, TCP/IP protocol and Socket network programming technologies has been mainly used to mask complicated network communication. The other is named by business dealing sub-system, which is represented for encapsulating business logic. In this sub-system, CORBA middleware is used in pursuit of good scalability.This thesis deeply discussed some key technologies in realization of system, including multi-threading problem, information mutual model between back sub-systems, data switch and data consistence. And then, this thesis discussed the extension of system from the aspects of load balance and Web-CORBA integration. Besides, this thesis also discussed some security policies used by this system. Briefly said, the achievements of this thesis lie in the following aspects: Brought forward and then realized a simultaneous server based on threading pool, and so improved the trade dealing ability of channel sub-system; Brought forward and realized an information mutual model based on CORBA Event Service, and so resolved the problem of efficient and asynchronous communication between two back sub-systems; Brought forward and realized an auto-recovery mechanism to ensure the consistence of trade data involving multi-organize; Besides, this thesis brought forward a load balance model based on extended CORBA Naming Service and Web-CORBA integration model based on Java to get better system applicability.In the end, we had an evolution on the developed system, and put forward some directions needed to research on the following days.
