COMRADE data management system storage and retrieval techniques
Ann Ellis Bandurski, Michael A. Wallace · 1973
The design of a data management software system involves the consolidation of a balanced set of individual techniques. Today's third generation computers provide the resources for the storage of large, complex sets of data, and for the rapid retrieval of that data. Random-access mass storage devices will store millions of bits of information, and central processors have instruction execution times on the scale of tenths of microseconds. But central memory space is limited and mass storage access time is not negligible.
