چکیده انگلیسی
The entity–relationship model (ERM) remains one of the most widely used SW Engineering techniques. Much research effort has focused on incorporating into database design in general, and ER modeling in particular, the historical support requirements arising from the temporal nature of dynamic domains. This paper discusses REERM, an extension to the enhanced ERM, whose primary objective is to address this problem, but that may bear positively on other aspects of conceptual modeling.REERM redefines the concept of entity, introduces additional relations classification criteria, adds the construct event and uses derived attributes and relations. Its application is illustrated with a case study.
