Recognizing the need to balance generality and economy in system costs, the Project INFO team at Stanford University developing OASIS has sought to provide generalized and powerful computer support within the normal range of operating and analytical requirements associated with university administration. The specific design objectives of the OASIS system are: (1) responsiveness to information needs, current and projected, of major university administrative offices; (2) support with both volume batch and teleprocessing requirements with reasonable efficiency from the same file; (3) fast terminal response and simultaneous batch program activity; (4) minimal system overhead and a favorable cost/performance ratio; (5) hardware and software reliability features appropriate to the demands of an online environment. This document covers the executive control services, data base services, terminal services, and generalized services of the OASIS system. Appendixes include the OASIS file structure components, network design, development plans, and command and reserved words. (Author/PG)
