图书馆系统数据库设计研究

Researches on Database Design of the Library System

比较大型、实用的图书馆信息管理系统在国内是不多的，而且由于文献管理方法、目录标准等方面的差异，不可能照搬外国现成的图书馆管理系统。为此，１９８８年起，华东师大计算中心受日本富士通公司的委托成功地开发了适合中国情况的集成图书馆管理信息系统ＩＬＩＳ（ＩｎｔｅｇｒａｔｅｄＬｉｂｒａｒｙＩｎｆｏｒｍａｔｉｏｎＳｙｓｔｅｍ）。本文着重分析ＩＬＩＳ数据库设计中碰到的问题：安全、完整、可恢复、响应时间等，并给出了几种设计方法；对实现ＩＬＩＳ数据库的关系数据库管理系统ＲＤＭ作一些性能上的分析，对ＩＬＩＳ的今后改进提出一点看法。

Not many practical large scale library information systems are there in our country. Foreign systems can't be used directly because of different ways in document management and catalog standard. Since 1988 Fujistu Company has entrusted the Computer Center of ECNU with developing the Integrated Library information System (ILIS). Problems in designing ILIS database such as security, integrity, recovery and responsing time are analysed in the paper. Various design methods are proposed and some simple analyses on RDM and directions to improve ILIS are presented.
