Seeking the candidate key of the relation scheme is an important procedure in normalizing relation. Although some methods on seeking it are shown by some reference materials,the concrete algorithm cannot be obtained.The paper demonstrates an algorithm by using the knowledge of the directed graph to seek the candidate key of a relation scheme.
