当您使用概念模型时，可以定义在符合网域的语言中何种资料为有效。
When you use a conceptual model, you can define what kind of data is valid in the language that matches your domain.
同时，为使高层应用易于对模型进行有效性和一致性检查，采用超图数据结构形式化地定义了上述模型的概念模型。
Besides, in order to facilitate applications to check affectivity and consistency of this model, a formal concept model based on hyper-graph data structure is proposed.
这样可让开发人员专注于概念模型，不需担心储存结构描述，也可以让他们有效率地撰写程序码并兼顾可维护性。
This allows developers to focus on the conceptual model without concern for the storage schema, and allows them to write code with efficiency and maintainability in mind.
