In this correspondence, we propose new classes of inclusion dependences as an extension of “generalization” based on the entity and association concept. Various kinds of extensions are discussed, and four classes (IND, IXG, UXG, and co-EXD) are evaluated from the viewpoint of database design. We present the complete inference axioms for each class and the polynomial of inference problems.
