Data base concepts applied to generalized programming packages
G. Cort Steinhorst, Barry L. Bateman, Daniel L. Curtis · 1974
Software "packages" are becoming more and more prevalent in both use and availability. These packages provide many useful functions, without the costly, time-consuming development and testing normally required to implement the desired operations. A disadvantage of many packages, however, is the difficulty in modifying them in order to receive the desired result, if the original resultant of the package is not totally satisfactory.
