On the Design and Evaluation of Data Bases
Peter Scheuermann · Computer · 1978
Within the past few years data base management systems have received an increasingly large share of the computing world's efforts. They are attractive, despite their high processing cost, because they relieve the programmer of the need to program gram frequently used operations such as access methods for complicated data structures and variable- length fields, records, and files. As data base management systems become more flexible they also allow unanticipated queries to be answered with relative ease.
