Founded on our characterization, we synthesize efficient algorithms for (a): computing the inference basis of a given set M of MVDs; (b): computing the dependency basis of a given attribute set w.r.t. M; and (c): solving the membership problem for MVDs. We also show that our ...

For any l ∈ A, if att(v, l) = v1 then v1 is called an attribute of v. Note that an XML tree T must be a tree. Since T is a tree the set of ancestors of a node v, is denoted by Ancestor(v). The children of a node v are also defined as in Definition 1 and we ...

relational databases where fuzziness of data appears in attribute values in forms of possibility attributions as well as proximity relations in attribute domain elements, called extended possibility-based fuzzy relational databases, a notion of semantic equivalence of fuzzy data is introduced in this ...
