据一篇题为“数据库的未来”的报告宣称,1993年美国的数据库软件市场的销售总额将达35亿美元,而1988年此项销售额仅为18亿美元。销售额的上升主要是因为分布式数据库管理技术的应用预料将增加之故。分布式数据库方面的进展也将使欧洲的数据库软件市场销售额大大增加。1988年这一销售额仅为12亿美元,1993年将上升到39亿美元。大多数机构目前都把它们的数据资料存储在不同的数据库系统中,这些数据库系统又在不同的计算机上运
According to a report entitled “The Future of the Database”, the total sales of the database software market in the United States in 1993 will reach 3.5 billion U.S. dollars. In 1988, this sales was only 1.8 billion U.S. dollars. The increase in sales is mainly due to the expected increase in the application of distributed database management technology. Advances in distributed databases will also increase the sales of database software markets in Europe. In 1988, this sales amounted to only 1.2 billion U.S. dollars, and it will rise to 3.9 billion U.S. dollars in 1993. Most agencies currently store their data in different database systems, which are then shipped on different computers.
