本文介绍了一种将局部地区网络(LAN)作为小型机终端而互相连接的方法。在这种主从结构的互连中,LAN中的每个工作站均可作为|小型机的一个终端使用,从而可方便地共享小型机丰富的软硬件资源。在此基础上,提出了一种联机检索数据库的方法,它使得LAN中的每个工作站均可作为联机数据库的前端机,可以运行各种前端检索软件包,以帮助用户更方便地检索数据库,同时提高了数据库的使用效率和降低了检索费用。
This article describes a way to connect local area networks (LANs) as minicomputer terminals. In this master-slave interconnect, each workstation in the LAN can be used as a terminal for the minicomputer, making it easy to share the rich hardware and software resources of the minicomputer. On this basis, a method of online searching database is proposed, which makes each workstation in the LAN can be used as the front end of online database, and can run various front-end retrieval software packages to help users to retrieve the database more conveniently, At the same time, it improves the efficiency of database usage and reduces the retrieval cost.
