Equivalence theorem for generalized dependencies in relational databases
In this paper, we present some new results related to the differential dependencies in relational databases. The main contributions are the following: 1. To introduce a new concept of generalized differential dependencies. 2 . To claim and proof the equivalence theorem of consequences in the worl...

| description |
In this paper, we present some new results related to the differential dependencies in
relational databases. The main contributions are the following:
1. To introduce a new concept of generalized differential dependencies.
2 . To claim and proof the equivalence theorem of consequences in the world of
all relations, the word of two-tuple relations and propositional logic for the generalized
differential dependencies.
3. To show an equivalence between generalized positive Boolean dependencies
and generalized differential dependencies. |
