ABSTRACT:
The invention concerns a method and system for storing and displaying an entity relationship diagram.

Thereby redundancy is eliminated and less storage locations are needed to store the diagram. The diagram comprises kernel entity sets K, attributive entity sets A, role entity sets P and relation entity sets R which are displayed on a display 9.
