    Abstract:

    Object—oriented concepts provide some useful methods for designing s rela-tional database.In this paper,the concept of inheritance constraints is given.The authors show that the inference rules for inheritance dependencies are sound and complete.Fur-thermore,a series of results about the closure of inheritance dependencies,the minimal set of inheritance dependence is obtained,which arc analogous to functional dependencies.
