Identifying relationships are a key concept in the context of weak entities, where a weak entity depends on a strong entity for its identification. A multivalued composite attribute can be used to represent the combination of attributes from the weak entity and its corresponding strong entity, which together form the identifying relationship. This is because the weak entity cannot be uniquely identified by its attributes alone and needs the strong entity's key attributes (possibly along with its own) to ensure uniqueness.
