一个实用的地质科学数据管理工具——中国火成岩数据库管理系统（CRDB）

火成岩研究的不断深入和测试技术的迅猛发展导致大量火成岩科学数据的海量积累，但是这些数据由于太分散而没有得到充分综合的利用，为此，设计开发了一个简单实用的火成岩科学数据管理系统（CRDB）。从地质科学数据的特点出发，以满足研究者对大量数据的综合管理和深入研究的需求为目标，设计了系统的数据结构。该系统实现了数据的录入、建库、查询、空间可视化、数据分析、数据和图形输出等功能，其中最突出的是二维、假三维等值线图的生成。该系统可单机使用，也可在Internet或局域网上运行，方便研究者，特别是研究团队对收集的数据或者自己手上掌握的数据进行管理、共享、分析和深入研究，具有很强的实用价值。详细介绍了中国火成岩数据库管理系统的数据结构、主要功能和特点。

A practical tool of geological data management:system of igneous rock database management system of China (CRDB)

The intensive study on igneous rocks and the rapid development of testing technology led to the accumulation of a large number of scientific data, but these data are too scattered to be fully used. Therefore, a practical tool of geological data management (CRDB) has been developed. Based on the characteristics of earth science data, to meet the demand of the integrated management of large amounts of data and intensive study by the researchers, we designed the system′s data structure. The functions of CRDB are: data entry, database building, query, spatial visualization, data analysis, data and graphical output etc., and the most notable functions are two-dimensional or three-dimensional contours generation. The CRDB can be used on stand-alone PC, also may run in the Internet or local area network to facilitate the researchers, especially the research team to managing, sharing, analyzing and deeply researching the collected data or their available data. The CRDB has a great practical value and its data structure, main functions and features are introduced in detail.
