Application-oriented Model-base System
Models are often thought as the abstraction of object,phenomenon,system and process.But the present model base system is good at the abstraction of process which starts from the input data to the results.And it falls short of the model composition.Based on the object-oriented methods,this paper aims to discuss a new application-oriented model base system.The structure of model interface parameter is abstracted into descriptive model (DM) which can be regarded a bridge between different models.Using object-oriented method,a series researches has been made focused on DM,and establish the application-oriented model-base system.The model working flow and user-oriented model inheritance mechanism were designed for applying and maintaining the model resource easily.A prototype system was designed and developed,and an application demonstration is shown to verify its feasibility.
