基于动态存储策略的数据管理系统

提出了一种按照存储策略实现对数据管理的方法，既有效地解决了数据量不断增长与存储容量限制的矛盾，又能够根据存储策略的动态调整，最大限度地保留有价值的数据。详细介绍了在遥感数据的存储管理中，动态存储策略模型的构建方式以及存储策略在数据管理系统的应用，根据数据的使用情况、生产情况和数据来源等多种因子评估数据价值，从而确定数据的保留时限，实现越有价值的数据保留时间越长的目的。

A Data Management System Based on Dynamic Storage Strategy

In this paper,a method of data management based on dynamic storage strategy is proposed. The proposed approach is able to deal with the conflict between increasing volume of data and limited storage capacity. Meanwhile,the approach is able to keep as much as possible valuable data online according to the dynamic adjustment of storage strategy. This paper introduces in detail the con-struction mode of dynamic storage strategy model and the application of storage strategy in data management system in the storage man-agement of remote sensing data. In the process of generating of storage strategy,several elements are considered including information of data usage,data production,data source,etc.,to determine appropriate data storage duration so that the more valuable the data is,the longer time the data stay online.
