A discussion of Community Information Utility (CIU) software from the standpoint of some of the services that the system must support, the overall system design, and some of the technical problems faced by software designers. Each service is examined with respect to (1) management of input and output messages; (2) required data structures, accessing techniques, and maintenance of data files; (3) relationship to other services; (4) computation and file access activity; (6) percentage of total CIU workload; and (7) security/privacy requirements. Conclusions are that it is necessary to learn more about (1) scheduling under heavy workloads; (2) the effects of program and system organization on the ability to sustain system response and availability; (3) how to measure system performance and to relate these measurements to specific recommendations for improvements; and (4) the databank size. Solutions lie in a thorough analysis of each potential service followed by simulation and the building of pilot computer applications. (Published in H. Sackman and B. Boehm (eds.), Planning Community Information Utilities, AFIPS Press, 1972.) (See also P-4781, P-4897, P-4898, P-4899, P-4908.) 38 pp.
This report is part of the RAND Corporation Paper series. The paper was a product of the RAND Corporation from 1948 to 2003 that captured speeches, memorials, and derivative research, usually prepared on authors' own time and meant to be the scholarly or scientific contribution of individual authors to their professional fields. Papers were less formal than reports and did not require rigorous peer review.
