Quizplus · Accepted Answer

Creating an entity relationship diagram is an iterative process, meaning that it involves multiple rounds of revisions and refinements to accurately represent the relationship between entities.

Answer: C
 While there is no hard and fast rule on the number of entities that can be included in an entity relationship diagram, it is a best practice to analyze and combine entities until you have seven or less to ensure that the diagram remains manageable and clear.

Note: options A, B, and E contain incorrect statements. There is no specific limit on the number of entities, relationships, or attributes that can be included in an entity relationship diagram.
