What is REA Model? How does it differ from traditional accounting systems?


The REA model is an accounting framework for modeling an organization’s critical resources, events, and agents and the relationships between them. Unlike some traditional accounting systems, REA systems permit both accounting and non-accounting data to be identified, captured, and stored in a centralized database. From this repository, user views can be constructed that meet the needs of all users in the organization. REA models may be implemented within either relational or object-oriented database architectures.
