A language for simple interactive retrieval from a database system

摘要

Query interaction with a database system requires, in general, some understanding of the content and structure of the database, and knowledge of a suitable query language to encode the request for data. These factors impose barriers against access to a database on a casual or irregular basis. To overcome such restrictions we have investigated the use of a pseudo-intelligent front-end retrieval system. This system was designed to be independent of any specific database management system, although a relational database structure was considered to be the most appropriate. A prototype version of the system has been set up to run on top of Logica's relational database management system RAPPORT and the IBM relational database system SQL. As a result of this experience we have developed an adaptable language to facilitate intelligent interaction between an end user and a database management system.
