A New Model Representation Method And Applying In Financial Accounting System

Decision Support System (DSS) has developed rapidly since its conception appeared in the 1970's.After continual probing,studying,applying,developing and perfecting of many experts and scholars in the academic world for more than 20 years,the connotation,theoretical basis and relation with other technologies of DSS's conception have already been obvious and are getting mature.Model management is one of keys of DSS,this paper studies the model representation methods of model base system. All the work can be concluded as follows:First,making a brief introduction of the principles and architectures of DSS;Second,comparing and analysis the current model representation methods in details;Third,advancing a model representation method called model oriented-object representation on the basis of studying oriented-object model representation method and oriented-object concept. The paper thinks model is also object,and they are corresponded one by one. Model is thought as integrate of data and methods (operations). Data field of object describes model's state,operation field of object describes model's behaviors,and operations of model are responded by messages. Structure functions send messages and realize operations to data in model objects. The forth,finishing the system design and software,including the initiative design,detailed design and software design. The system that has been developed is running successfully. The fifth,building up a model management under the environment of the sale accounting system.
