引言电子计算机用于数据库检索是一项尚处于早期阶段的发展中技术。在较近的将来,许多今天所采用的技术将仅具历史意义。当前,数据库检索主要是依靠中央大型计算机,通过电话系统或专门的数据网络将终端连接至中央大型计算机作“分时”处理。目前处于实验阶段的全文检索、计算机查找数据……等,在最近的将来将变为现实;高速数据网络将能连接至科研人员办公桌上的微型计算机上。而且,两者的价格将愈来愈低廉,但相对来说,计算机价格的下降将更显著。
Introduction The use of electronic computers for database retrieval is a developing technology that is still at an early stage. In the near future, many of today’s technologies will only be historical. At present, database retrieval mainly relies on the central large-scale computer to connect the terminal to the central large-scale computer through the telephone system or a special data network for “time-sharing” processing. The full-text search, computer search data, etc. currently in the experimental stage will become reality in the near future; the high-speed data network will be able to connect to the microcomputer on the researcher’s desk. Moreover, the price of the two will become lower and lower, but relatively speaking, the decline in computer prices will be even more pronounced.
