Dependency rules define the many-to-one relationships between attributes (fields/columns) in a single entity. They consist of a left-hand side (LHS) which is composed of one or more attributes, and a right-hand side (RHS) composed of a single attribute.

In a dependency rule, the "LEFT-HAND side" or LHS attributes determines the "RIGHT-HAND side" or RHS attribute, represented as LHS g RHS.

For all dependency rules, the value in the LHS attribute(s) always determines the value in the RHS attribute. Certain dependency rules may be bilateral (LHS g RHS AND LHS f RHS), but only if the data supports this. The majority of dependency rules are LHS g RHS only.
