STRUKTURISASI ENTITY RELATIONSHIP DIAGRAM DAN DATA FLOW DIAGRAM BERBA SIS BUSINESS EVENT-DRIVEN

Entity relationship diagram (ERD) and data flow diagram (DFD) modeling are necessary parts inanalysis and design of structured information systems inbusiness. Definition of entities in the ERD, the process,and datastore in the DFD have well described in a lot ofliteratures. However, practically it is not easy toexplain how to design ERD and DFD models so that the students well understand the modeling steps, especiallyin business applications. This study discussed step-by-step systematic approach to ERD and DFD modelingusing ”business event-driven” approachthat is represented by the REAmodel, through structuring REA-ERDand REA-DFD. From the results we concluded that the logical design of ERD shouldbe done before designingDFD, so that there would be perfect ”balancing” between the entities in the ERD and data stores in the DFD.Consequently, the implementation of these steps needed to be tested both qualitatively and quantitatively inadvanced researche
