A Method to Find All Can■ate Keys of Relational Schema Based on Basic Cycle
In this paper,the theory and theorems of candidate keys of relational schema to which classified quasi-cycles corresponding are discussed.The methods to find candidate keys of relational chema to which quasi-cycles corresponding and to which hypergraph corresponding based on basic squasi-cycle are given.
