Research On The Method Of Dynamic Assembly In Business-component-based Systems

Currently, most of the research is focused on the software component model andthe interoperability between the software components, while less on the process ofabstracting and achieving the business system. Reuse and assembly level areconcentrated in the code of the software component as well as the underlying data layer,communications layer. The gap between the abstraction and the achievement of thebusiness system is increasingly widened, resulting in the process of developing thebusiness system is more difficult to control and maintenance. We proposed a set ofmethods to abstract and assembly the business system.Firstly, this paper find the methods to abstract, achieve and assembly the businesscomponents of the business system. To begin with the dynamic assembly process of thebusiness system, this paper proposed a set of methods, which is built on the principle ofthe relationship between atomic functions, to abstract the business component-basedsystem. And, we built the mapping mechanism from the business components to thesoftware components. Through the research on the architecture of the businesscomponent-based system, we solved the problem of coupling between the hierarchicalstructure of the business system.Secondly, this paper created a framework named BCOAF to support themechanism of the assembly of the business component-based system. This paper setforth the use of all the parts of the framework and the control of the life cycle of theobjects managed by the framework. At last, this paper put forward the core algorithm,which is driven by Qos, to the assembly of the business component-based system.Finally, this paper presented the core design of the framework such as use casediagrams, database diagrams, the overall class diagrams, hierarchical organization chartand so on. The dynamic assembly process of the business system was analyzed in detail.This paper proposed the hierarchical structure of the function component based on Flexand the entity component based on Spring. At last, this paper analyzed the runningprocess of the framework and gave many user interfaces.
