On the properties of extended inclusion dependences
Hiroshi Arisawa, Takao Miura · IEEE Transactions on Software Engineering · 1986
New classes of inclusion dependences are proposed 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. The complete inference axioms for each class and the polynomial of inference problems are presented.
