Abstract:In this paper,we difined the conception of strong primary attribute and discussed the topological sequence structure of the attribute subset.A new algorithm for solving all candidate keys of relation schema is found.
Keywords:database  relation schema  candidate keys  function dependencies  strong primary attributes  topological sequence structure
