Distributed Ground-Water Data Base of the U.S.G.S.by Richard R. Luckey, US Geological Survey, Denver, CO, USA,
Abstract: During the past 20 years, the ground-water data base of the U. S. Geological Survey has evolved from paper files in local offices, to a national data base on a central mainframe computer, to a distributed data base on a network of 49 minicomputers throughout the United States. Users in local offices have easy, inexpensive access to the distributed data base. The distributed data base has caused some problems in data management but has increased the overall quality of the data base.
