摘要
地质数据中存在大量非标准化的数据,此类数据主要以MapGIS的数据格式存储。针对此类数据管理难、复用水平较低的现状,建立了以元数据服务器(MDS)为核心的数据存储模式,提出了弹性的迁移机制完成数据的重构,使用了动态数据驱动生成索引元数据框架,同时实现数据访问安全机制,用户授权等功能。此模式利用MDS(MetadataServer)实现对数据的管理、检索和调阅,这使散落在单机上的地质数据能够自主迁入空间数据仓库,实现统一管理,增强了数据的可复用性。
There is a large amount of non-standard data in geological data, this kind of data is mainly stored by MapGIS data format. In this paper, we focus on the difficulty of the centralization of management of these data, and the current situation of low level of overall exploit. Moreover we establish the data storage mode based on the form of multiple catalogs Metadata server, and propose a stretch migration mechanism to accomplish the reconstruction of data. It employs the dynamic data driven to produce the framework algorithm to attract the metadata infrastructure. At the same time, we accomplish the safe mechanism of data access and user authorization, etc. This method uses the MDS （Metadata Server） to accomplish the management, search and accessing of the data. This makes the geological data that scattered over the MDS can settle in the data warehouse by itself to achieve the centralization of management and strengthen the reusability of the data.
