Relational Database Design Using Rea Data Model

Once these steps are complete, the design of the relational database from and REA model follows in the same manner as it would from traditional entity-relationship diagrams. A. REA Models versus ER Diagrams This section compares REA and ER modeling. Of particular note, while ER models include operating, information, and decisionmanagement

Database design using the REA data model REA How to design and document a relational database for an AIS. Accountants may provide the greatest value to their organizations by taking responsibility for data modeling. Data modeling is the process of defining a database so that it faithfully represents all aspects of the organization, including

This document discusses database design using the REA data model. It explains that the REA model classifies entities into resources, events and agents. Resources are things of economic value, events are business activities, and agents are people or organizations involved in events. The REA model prescribes that every event must affect a resource and be linked to another event, and every event

The document discusses the steps in database design including planning, requirements analysis, design, coding, implementation, and operation and maintenance. It emphasizes the importance of data modeling using entity-relationship diagrams and the REA data model during requirements analysis and design. Accountants can participate in all stages but have the greatest value in taking
