【摘要】 DSS中的模型可以用不同语言,按照不同的规范编写,所以模型的数据格式各不相同,如何从数据库中获取所需格式的数据是开发决策支持系统必需解决的问题。设计了面向对象模型库结构,提出了一种使用规范的数据描述文件(MDF)进行模型封装的方法,实现了规范化的面向对象的模型库与数据库接口。更多还原

【Abstract】 It is an inevitable problem that there exists different types of data for models in DSS because different languages programmed models are in the same model base of decision support system.Firstly,the model object base system by the object oriented techniques is introduced,then a method of model normalization is proposed,which normalizes the interface between model units and data units and its consistency is guaranteed.更多还原
