Design considerations for CD-ROM retrieval software
Edward M. Cichocki, Susan M. Ziemer · Journal of the American Society for Information Science · 1988
The CD-ROM requires a different kind of retrieval system design from systems on magnetic media because the disc's physical characteristics and drive differ from those of magnetic media. Retrieval system designers must be concerned with ways to minimize seeks (access time), transfer large amounts of data following each seek, store data proximally, and maximize CD-ROM performance. Three methods to maximize that performance are described: single key mode, multiple key mode, and inverted file mode. Well-conceived design and well-executed retrieval systems for CD-ROM databases can result in performance that equals the state-of-the-art on-line systems. © 1988 John Wiley & Sons, Inc.
