Abstract
Summary: Computerized information systems which create, maintain and extract data from files of structured information share common processing characteristics regardless of the application to which they are being applied. Implementation and maintenance of such a system is greatly facilitated by the use of packages of generalized computer programs which are designed to perform all of the traditional information handling functions and which can be readily adapted to a wide range of data storage and search requirements. Such program packages minimize cost of system implementation and permit limited resources to be dedicated to the storage of data and the operation of the system rather than to its development.To illustrate the characteristics and capabilities of such program packages, one example, the IBM Generalized Information System (GIS) is examined in some detail.
