RISS: a generalized minicomputer relational data base management system

With the recent growth in popularity of low cost, relatively powerful minicomputers, it is clear that associated data base management systems are required. Nearly all of the minicomputer systems that are currently available commercially have at most rudimentary data base management capabilities. Consequently, in this paper we discuss the design and implementation of a minicomputer relational data base management system: the Relational Inquiry and Storage System (RISS). RISS provides a "naive" user interface, to allow nonprogrammers to deal routinely with a data base without the aid of a programmer, as well as an applications program interface. These interfaces facilitate data base access, modification, and restructure. RISS is a generalized and context-adaptable system, but it maintains a degree of efficiency guaranteeing cost-effective operation.
