应用计算机进行档案(文件级)著录的存储、检索时,主题词标引和用于手工检索系统的主题词标引比较,有许多特点。对此,我们应在今后实践中不断摸索。一、机检系统的功能特点计算机档案文件检索系统,比手工检索系统,有很大的优越性。 1、存储容量大、占用空间小,检索迅速而准确。建立档案(文件级)著录数据库,一块十兆字节的硬盘能存储三万多个文件的著录信息,检索一个文件著录信息只需几秒到几十秒。 2、某一信息、数据一次输入后,可以做多样化的输出。例如将每个文件的著录信息输入计算机之后,就可以用于检索(从多角度检索),编目,统计,复制……多样化的输出。 3、对已存储的信息需要增加、删除、修改时,非常方便,可随时进行,不象手工系统那样困难。
There are many characteristics when using computer to store and retrieve the records (file level), comparing the indexing of keywords and the indexing of keywords for manual retrieval system. In this regard, we should keep exploring in the future practice. First, the machine inspection system features Computer file retrieval system, than manual retrieval system, a great advantage. 1, large storage capacity, small footprint, fast and accurate retrieval. Create a file (file level) Bibliographic database, a ten-megabyte hard drive can store more than 30,000 bibliographic information, retrieve a file to record information only a few seconds to tens of seconds. 2, a certain information, data input once, you can do a variety of output. For example, the bibliographic information of each file can be used for retrieval (from multiple perspectives), cataloging, statistics, copying, etc., into various kinds of output. 3, the stored information needs to be added, deleted, modified, very convenient, can be carried out at any time, unlike the manual system as difficult.
