Abstract

Currently, there are many problems of the application development of E-Learning platform such as the difficulty to use learning object from an LMS in another one, and the domain model reuse rate is low in various application systems, and hardness to ensure the consistency between designs and codes. These problems have constrained the development efficiency of E-Learning application software and its quality. In this paper, we proposed a model-driven development approach for E-Learning platform. First, establish the domain model (CIM) through the analysis of business logic, and then establish robustness diagram of the system after the robustness analysis. Then we stratified on the PIM under the J2EE framework, and proposed the method of transformation from PIM to PSM layer by layer. This approach not only effectively solves the above problems, but also improves the efficiency of software development through the automatically generated code.
