The introduction of the term database coincided with the availability of direct-access storage (disks and drums) from the mid-1960s onwards. The term represented a contrast with the tape-based systems of the past, allowing shared interactive use rather than daily batch processing.The Oxford English Dictionary cites a 1962 report by the System Development Corporation of California as the first
