Generalizing persons and organizations into a “party” entity allows them to assume roles in agreements, share addresses, and participate in common processes. The DAMA-DMBOK states: “The party concept in data modeling generalizes persons and organizations, enabling them to act in roles (e.g., customer, supplier) and share attributes like addresses or interactions” (DMBOK2, Chapter 5: Data Modeling and Design, p. 187).

Options A, B, C, and E are less accurate: A is too narrow, B is a secondary benefit, C is implementation-specific, and E is unrelated to modeling.
