Design and implementation of RAQUEL II: a relational query language

ABSTRACT

This paper describes RAQUEL II, a query language to be used within a relational data base management system. The RAQUEL II language is a modification of RAQUEL (Relational Algebraic Query Language) [7,8], a language which is easy to learn and to use. Some features of RAQUEL have been omitted, some modified, and others extended. The intent has been to define a minimal set of commands which are still powerful enough to provide ease of creation, modification, and manipulation of data. All RAQUEL II features are desirable for the user. In passing, we note that several features are also important for certain noteworthy implementation objectives. The RAQUEL II system is currently being implemented at Florida Technological University on an IBM 370 within an OS environment.
