The Design And Application Of Service-Oriented Configuration System

For the development of the information system,the system of the same field have many similarities,even the information system in different areas also have some similarities,How to reuse the existing similar parts to improve the efficiency of development has always been a hot spot for developers.Usually,software components are used for the realization of configurable systems,but software component technology means only the reuse of software components,but for the public behavior in components,the reusability is not enough.Based on the technology of software component,this thesis introduces the Aspect Oriented Programming.Research on improving the reusability of behavior in components,and it has an important practical significance for improving the efficiency of the development of information system.Based on reading a lot of references at home and abroad,this paper makes in-depth research on the related theoretical knowledge based on software component technology,section oriented technology and configurable system,in component technology,the concept of face oriented is introduced to establish the classification of components,the principle of component selection,the analysis and design methods of components,a component developed into a small size of the same functional behavior in a component based on Aspect Oriented Programming,these small size components can not only be applied to systems in the same field,but also can be applied to similar functions in other fields,which will greatly improve the reusability.After the design and development of the component,the XML language is used to describe and assemble the components,this thesis has studied the specification of document,the language specification of description file,and the description information specification of component and component connection.We have assembled the component into a configurable information system through XML language.Finally,the proposed component design method is applied to the development of the actual vegetable distribution system,around the functional requirements in order,purchase,distribution,inventory,etc.,we can achieve orders to be allocated flexibly through procurement,distribution,or order through inventory to distribution,this makes the reusability of the functional behavior better,and improves the efficiency of the development of the information system.
