| Abstract: | The core design of conceptual model in database design is the design of E-R model. In the design practice, Designers feel more confused is to determine the relationship of entities, attributes the choice between. In this paper presents how to select entity, How to determine the attributes of entities and how to determine the link between the entity.This article is to focus on the problem. |
