WebApr 17, 2024 · Let A be a nonempty set. The equality relation on A is an equivalence relation. This relation is also called the identity relation on A and is denoted by IA, where. IA = {(x, x) x ∈ A}. Define the relation ∼ on R as follows: For a, b ∈ R, a ∼ b if and only if there exists an integer k such that a − b = 2kπ. WebFor any relation R, attribute Y is functionally dependent on attribute X (usually the PK), if for every valid instance of X, that value of X uniquely determines the value of Y. This relationship is indicated by the representation below : X ———-> Y The left side of the above FD diagram is called the determinant, and the right side is the dependent.
