Roadi Reusable Program And Its Research Of The Case Environment

This project researched the ROADf approach that involved benefit from tho object-oriented approach and the traditional structured approach, and develop a CASE tool based on the ROAD I. We also discussed issues about how the ROADI provides support to assembles the reusable components.The ROADI approach provided the solution to the 'flat' object-oriented modeling approach which can not perform the hierarchical decomposition and refine-step-by-step. The ROADI applies the Object Data Flow Diagram (ODFD) to guarantee that all layers in the object data flow diagram are 'data balance' , i.e. input and output to each refinement must remain the same. Our research introduced XML to the ROADI, that maps Java data structure of the ODFD to the XML files. The ODFD to store in XML files may get much benefit from the system model reuse.
