Quizplus · Accepted Answer

The REA (Resources, Events, Agents) model deals specifically with the relationships between resources, events, and agents. It is used to design a relational database and helps to determine the entity relationships, attributes, and cardinalities. Therefore, the mapping of relationships between entities would be used in the development of an REA model. The other options are used in different stages of the system development life cycle, but are not specifically designed for mapping entity relationships.
