The architecture description of an enterprise system is created and used according to a set of guidelines known as an enterprise architecture (EA) framework. By organizing the architectural description into domains, levels, or perspectives and offering models for recording each view, it facilitates the organization of architects' thought processes. Decisions on systemic design, long-term planning, and the control of scale and complexity of business systems are made possible by this. The Zachman Framework and TOGAF are two well-known EA frameworks that divide an architecture into layers or domains according to the essential application logic.
