专题数据库开发中的文献粒度问题研究——以《桂西北少数民族历史、文化资源数据库》为例

在专题数据库开发中，图书的著录和实体资源封装以种为最小单元，无法充分揭示部分图书的内容特征、学术价值和发挥专题数据库的文献整合利用功能，易于造成数据冗余。应遵循“有利于检索发现，有利于读者使用，有利于提高开发效率”原则，根据实际情况，选择“章节”或者“篇”作为文集类、资料汇编类、综合性图书著录与实体资源封装的最小单元。

Granularity Problems in the Development of Special Databas：Taking＇The Guangxi Northwest Minority History ＆ Cultural Resources Database＂ as an Example

In the process of developing special database, type is used as the minimum unit to describe ＂document and encapsulate entity. It can＇t fully reveal the content features, academic value of some literatures and develop the functions of literature integration and utility of special database. So, it easily causes the data redundancy. Followed the principle of ＂easy to retrieve, easy to use for readers and easy to improve the efficiency of development＂ and based on the fact, chapter should be chosen as the minimum unit of collected works, data compilation, comprehensive books and entity encapsulation.
