Research And Implementation Of Service-oriented System Development Platform Based On Global Information Model

Along with the rapid development of Information Construction and as the economic globalization continuously improving,information systems must have the ability to adjust to the market and Technology Fields' requirements at any moment. Service-oriented architecture(SOA) is becoming a leading paradigm for information planning,application integration and system engineering.It is perfect paradigm for system cooperation and reuse,and for keeping business agile and information system flexible.Web service has been envisioned as the appropriate technology for SOA implementing.With service-oriented software engineering methods as entry point,our research team has proposed a business-centric,multi-model driven,multi-views synchronized and multi-role collaborating service-oriented requirement collaborative development method.Based on this method,a multi-model driven service-oriented engineering platform is built.The platform employs three models,i.e.,business model,process model and service meta-model to construct business view,process view and service view to support visualized modeling.Engineers with different background can involve system designing,work collaboratively through different views and different place,and reach business-centric requirement driven development.It shortens the development period and enhances communication,which is an innovative attempt for service-oriented software engineering.This paper discusses and implements a Global Information Model which supports multi-model information for consistent and synchronized multi-view based on the above and Multi-Model driven Service-Oriented system development platform.The paper proposed the design requirement of the Global Information Model by analysis of the limitations of the existing multi-model design platform,compared to other design methods of other areas of the global model to study the design pattern of the paper and outline the design of the Global Information Model,and then discussed the development technology of the Global Information Model,in order to maintain synchronization of multi-view information it designed conversion rules and conversion algorithm between other model and the Global Information Model, compiled the Global Information Model and get executable service composition description file.Furthermore,this paper also discussed Service-Oriented system development platform in a specific field of Service-Oriented system development process of the application of the general steps based on the Global Information Model. Improved platform also adds a new portal Service-Oriented view management system for the demonstration run,thus there are four models to support the development of Service-Oriented systems,especially to the application of the court system development environment,business and technical engineers can conduct the development of visualization business process modeling,service modeling and system prototype in different places.Finally,the intelligent trail system was used to validate the research ideas in this article,combined with the global information model changes in the contents of the documents to demonstrate Service-Oriented system development process in specific areas.
