计算机应用系统,依赖于一个大的档案信息数据库,有了这个数据库,我们就可从库中获得档案管理过程中所需的各种资料和数据(如编目、检索、管理、统计分析等),去指导档案馆的一切业务活动,但是这样一个主数据库的数据(即存贮于计算机中的档案文件的形式特征和主题内容)应如何组织,选取什么?按什么原则选取?即数据的逻辑结构怎样,是非常重要的,对建立档案信息总数据库来说,就是解决设计数据库结构和系统前处理(著录与标引)两个方面的工作。一关系型档案数据库的特点从全国来看,绝大多数档案馆(室)在使用计算机的选型上,基本上都是采用微型计算机,这种选择对于现阶段的档案部门来说,是符合实际的。但微型计算机有一定局限性,它存贮容量小,软件资源有限。要在微型计算机上建立数据库,目前主要还是利用厂家所提供的数据库管理系统(DBMS),进行二次开发,才能构成档案信息数据库。在这种条件下,目前
Computer application system relies on a large file information database. With this database, we can get all kinds of data and data (such as cataloging, retrieval, management, statistical analysis) needed in the file management process from the library, To guide the archives of all business activities, but the data of such a main database (ie, stored in the computer archives of the formal characteristics and thematic content) should be organized, what to choose? What is the principle of selection? That the logical structure of the data How, is very important, for the establishment of the total file information database, is to solve the design database structure and system preprocessing (bibliography and indexing) two aspects of the work. The characteristics of a relational archives database From the national point of view, the vast majority of archives (room) in the use of computer selection, are basically using a microcomputer, this choice for the current archives department, is in line with Real. However, there are some limitations of microcomputers, which have small storage capacity and limited software resources. To build a database on the microcomputer, the main still use the database management system (DBMS) provided by the manufacturer for secondary development, to form a file information database. Under such conditions, at present
