Research On The Development Method Of Enterprise Information System Based On Model Driven Architecture

In the process of enterprise information, building enterprise information systems is an important content.At present,the enterprise information systems generally exists the problems of inefficient development, poor expanding capacity and transplant issues.This requires a unified management and coordination mechanism to deal with the functional modules(component) within the system .Model driven architecture (MDA) is the Object Management Organization (OMG) released a software development framework, The aim is to separate the business and application from the underlying technology platform. MDA as a new method of software development, committed to improving the software development to the abstract level, to define the business logic as the precise model of high-level abstraction. It makes the model for the entire software development process, through the requirement analysis, design, implementation and maintenance of the entire process. It not only resolves the existed problem of traditional software development,but also complements each other with other new methods. So it uncovers a new literary piece for the software development.This paper first make a brief introduction of relevant technologies; then presents an approach based on model driven architecture(MDA) for the development of enterprise information system, and proposes a framework based on MDA. Then designes a business domain meta-model independently, by using UML Profile models enterprise PIM and PSM, Presenting a rule to descirbs business domain PIM transforms to PSM by using Relation language of QVT (Query/View/ Transformation),And implement this rule in the open-source tool—mediniQVT. Moreover, implements transformation from PSM to CODE under EMF (Eclipse Modeling Framework) is which presented by IBM,Thereby, to realize a model-driven development process based on the model.Last,apply this method on a contract tracking Theme of DSS of an iron and steel enterprise. It indicates that the method in the paper increase the efficiency of System Development compares to the traditional method. Therefore, makes the model having more normative, realizes the share between models. Meanwhile, it profits the re-use and maintain of model.
