基于CORBA业务组件的领域框架研究

RESEARCH ON DOMAIN FRAMEWORK BASED ON THE CORBA BUSINESS COMPONENT

面向对象技术的出现为计算机软件开发技术的发展带来了一个前所未有的飞跃 .但是 ,仅仅依靠面向对象技术中单个的对象、类还不能保证软件设计与代码的重用 .因此需要一些专门的技术来提高重用率 ,从而降低软件开发工作量 ,提高开发效率 .组件与框架技术的出现为这一需求提供了解决方案 .本文提出的基于 CORBA业务组件的领域框架结合了组件技术和框架技术的优势 ,其目的是通过提高软件设计与代码的重用率 ,为广阔的计算机应用领域提供高可靠、易开发、易维护的分布式计算软件 .本文以我们开发的基于 CORBA业务组件的领域框架为基础 ,介绍了其理论背景。

The object oriented technique is a genuine advance in software development technology. However, using the object oriented technique alone objects, classes doesnt guarantee reuse of design and code. Specific strategies are needed for using these designs and programming techniques to reduce the workload and improve productivity. Techniques of component and framework are introduced to meet this challenge. The domain framework based on CORBA business component we present in this paper combines the predominance of the component and framework. It aims at the improvement of software reuse and the development of highly reliable and easily maintainable distributed computing software in a wide range of domain. The paper presents the theoretical fundamental of the framework, outline its architecture and analyze its key technology.
