Abstract: The management system of evaluating advanced research project is a document MIS which integrates the C/S and B/S mode. This paper uses GRASP as the basic design pattern. After analyzing and designing the system’s architecture, conceptual model, it assigns responsibility to the objects and designs the persistent objects. At the end , it discusses two key problems and their resolving methods: the first is how to fast find a field in a word document, the second is how to extend system to restrict voting process.
