Abstract : A method for relational database scheme design with the aid of a digital computer for a database having attributes Ai, i = 1 to n and relational schemes Rj, j = 1 to m. Each relational scheme Rj is a non-empty subset of the attributes Ai. The method detects any scheme that is non-acyclic in a simple manner that is easily adapted to a digital computer environment. The resulting relational database scheme design is thereby prevented from being non-acyclic.
