银行传统语言系统的面向对象和服务架构的研究
|
摘要
随着现代银行业务的迅猛发展,银行提供越来越多的功能的服务,从而导致银行软件系统日益复杂化。然而银行系统由于对系统性能的高要求,通常使用IBM Mainframe之类的高性能主机系统,在这些系统上通常使用COBOL或C这样的传统语言,这些系统经过多年的开发积累,有着大量的特定应用代码,所以不太可能从根本上全部替换掉。一方面硬件不停的升级,速度越来越快,另一方面软件系统依然沿用十年前甚至更老的架构。但是随着银行业务的增加和更新,系统日益复杂,系统开发和维护的难度越来越高。如何在现有系统上更有效的开发和维护系统是银行开发人员面对的一大难题。
本文针对这些问题,通过分析典型的个人银行结构和业务,在现有系统的基础上,参考面向对象和面向服务的思想对其进行改造,提出新的应用框架模型。按照功能对数据和操作重新划分和封装,以提供更高层的抽象能力,从而达到封装变化、实现复用的目的。用较小的代价优化系统以满足易于维护和开发的目标。最后通过具体的案例来说明新构架的效果。
通过对新的软件架构的研究和应用,提升了系统面对变化的应变能力,有效的降低系统开发和维护的成本。为具有同样问题的银行系统提供一个可供借鉴的解决方案,并且可为其它类似的传统系统开发提供参考。
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.
