alleryStart learning →The domain of a multi-valued attribute is
Athe same as the basic domain of a single value
Bthe cross product of the basic domain with itself
Calways restricted to two or more values
Dthe set of subsets (power set) of the basic domain
Answer & Solution
Correct answer: D. the set of subsets (power set) of the basic domain
A multi-valued attribute can carry any subset of values, including the empty set.
**NPTEL:** 'Domain of multi-valued attributes: set of subsets of values from the basic domain.' Cross product is the rule for composite attributes
same-as-basic skips the 'set' aspect.
