The Research And Implementation Of Component-Based Telecom Integration Business System Framework

Software component technology is the pivotal technology to the software reuse. Especially recently its rapid development is paid on attention highly. The Object Oriented framework supports not only the code reuse, but also the design reuse. Thus it can improve the development efficiency and product quality of specific domain application software. At the same time, scholars found some deficiencies of the Object Oriented framework, such as " Excessive Proliferation", "Fragile Base Class", Implicit Architecture" and etc.Combining the research practice in the national 863 project -"domain oriented application framework and component technology", the author have done some deeper study on the concept, structure and development methods of framework while studying the software component. Accordingly this paper put forward the idea of adopting the component-based framework, that is the developer can transfer the Object Oriented framework into the component-based framework through replacing overloading of method in component interface. The latter is more flexible and easier to be used than the former. Then designed and implemented the component-based telecom integration business system framework, which can support the development of telecom integration business system software. There are some concrete tasks as follows:1. Identified and extracted the common domain component by analyzing many telecom integration business systems.2. Established the system architecture of telecom integration business system by using popular 3(N) tiers architecture.3. Designed and implemented component-based telecom integration business system framework after consulting the IBM San Francisco commerce system architecture.4. Designed and implemented integration mechanisms to support the development specific application system.
