人事档案管理是所有厂矿、公司、企事业单位所必需的，人事档案管理系统包括对人事档案的统计、查询、更新、打印输出等功能。如果人工直接统计，工作量将很大，若公司人员有几万甚至几十万，人工统计将变得不可想象。用计算机可使人们从繁重的劳动中解脱出来，仅使用一些简单的操作便可及时、准确地统计需要的信息。(Personnel file management is necessary for all factories, mines, companies, enterprises and institutions. The personnel file management system includes the functions of statistics, inquiries, updates, print and output of personnel files. If the manual statistics, the workload will be very large, if the company has tens of thousands or even hundreds of thousands of people, artificial statistics will become unimaginable.
