The Application Research on the Visual Data Modeling in the Information System Analysis and Design

All the major methods of modeling design in use each have their own characteristics, but none of them can fully satisfied the requirement of architecture data modeling design. To settle this problem, the ideology of visual modeling is introduced to bring into play the advantages of structural analysis method, object-oriented analysis method and model driving architecture method that are applied at different layers of architecture data modeling respectively, so as to solve the concrete problem of each layer with a clear aim. In addition, focusing on visual data modeling, the system of architecture data modeling technology comes into being, and preferable meets the application requirement of large-scaled and complex information system analysis and design.
