Abstract: This paper puts forward a new data management model: data management model based on meta-directory. An application instance is given to make the model understood more clearly. This new model has many advantages such as flexibility and adaptability. The model is applied in many practical applications such as integrating data, on-time sharing data and controlling data. It is especially useful in integrating and applying abundant data.

Key words: Meta-directory, Storage schema, Base schema, Structure schema, Presentation schema

摘要： 提出了一种新的基于元目录的数据管理模型，给出了一个应用案例。该模型结构灵活、适应性强，可以有效实现数据整合、数据实时共享和数据可控，适用于大规模数据的数据整合和数据应用。
