Implementing an extended functional data model using PS‐algol
Krishna G. Kulkarni, Malcolm P. Atkinson · Software Practice and Experience · 1987
Abstract A number of data models have been proposed in the literature to improve the usability of database systems. Most of these proposals have not been implemented. It is felt that a working implementation is a necessary prerequisite for a serious study of these proposals. So far, implementing data models has been a daunting task, requiring a large team. We report here on a simple implementation technique using the persistent algorithmic language. PS‐algol, which promises to make the task of implementing data models a manageable one. The feasibility of the approach is demonstrated by implementing an entity‐based functional data model (extended function data model) using PS‐algol.
