Bank Of Traditional Language Object-oriented And Service Structure

With the fast development of modern banking product, Bank needs to provide more and more service for these new functions, which cause banking software to be much more complex than before. But due to the needs of high performance, it is quite common to use high performance computer system like IBM mainframe. On these platforms, banking software developers are using traditional language like COBOL and C to create banking system. After many year developments, there are lots of software applications, so it is almost impossible to replace the whole system. While the hardware upgrades to be faster and faster, the software is still same as ten or more years ago. But with the banking service updating, software system become more complex, development and maintenance become much more difficult. Now the problem is how to develop and maintain based on existed system.This paper tries to solve the problem by analyzing standard personal banking structure and business, based on current system and reference the concept of Object Oriented and Service Oriented, to create a new architecture model. Reorganize and encapsulate the data and operation to realize the high level abstract. So the system may isolate changes and be more reusable. And the total effort would be much less than replace the whole software system. To prove the benefit of the new architecture, a real case will be used to certificate.Using the new banking architecture, it would help to handle new requirement and changes, significantly reduce the development and maintenance cost. It can be a sample for other similar banking system, and could be treat as a reference for other traditional system.
