Research on Application of Model-Driven Architecture in the Development Process of Enterprise Information System

Information system used by enterprises at present has lower implementation efficiency and success rate. In order to make enterprise information system meet the changes of business requirements in a quick method and low cost, the deficiencies in current development methods of enterprise information system were analyzed and, for solving these deficiencies, a quick development pattern combined with the technologies and ideas of MDA (modern-driven architecture) was built. Four model types, CIM (computer independent model), PIM (platform independent model), PSM (platform specific model) and code, were included in this pattern. Moreover, for distinguishing the business requirement oriented and process oriented modeling course, CIM model was further divided into two types, CIM-business and CIM-ESA, and the model structure of CIM-business layer was studied in details. Finally, based on the structure, a graphical modeling example was constructed for validating its practicability and feasibility.
