Automatic application program interface to a data base
William David Haseman, Andrew B. Whinston · The Computer Journal · 1977
As the availabilities of data base management systems become greater the need to interface already existing programs with the data base will become important. This paper presents a technique whereby these programs can be interfaced automatically with the data base through the use of a query/extraction interface, thus providing the capability to retrieve, modify and use data in various application programs without knowing the physical data structure and without using the data manipulation language.
