Processing of Inverted Files in Magnetic Bubble Memories.
Peer reviewed Peer reviewed
Zaki, M.; Elboraey, F. – Information Processing and Management, 1985
Investigates applicability of inverted file processing in magnetic bubble memories by presenting four magnetic bubble memory models as storage mediums: one based on a major-minor loop configuration; one utilizing a decoder design on a magnetic bubble memory chip; and two based on different structural configurations of the first two. (MBR)

Handbook of Methods for Information Systems Analysts and Designers. Volume I - Basic Handbook and Appendix I. Final Technical Report.
Altman, James W.; And Others – 1971
A generalizable procedure for the analysis and design of information systems is described in the context of allied and supporting data methods, design assessment, and project management considerations. This procedure follows from a view of information systems development as a complex series of goal-directed iterations, rather than a well-ordered…

Martin, Thomas H. – 1974
The command language features of 11 on-line information retrieval systems are presented in terms of the functional needs of a searcher sitting at a terminal. Functional areas considered are: becoming familiar with the system, receiving help when in trouble, regulating usage, selecting a data base, formulating simple queries, expressing single…
