    Lightbulb The Entity Relationship Model Limitations

    Hey


    i am looking for an online article, or i 'll be delighted if u can explain me, about Entity Relationship Model Limitation.

    Has this model any limitation?

    also how can i decide upon modeling a concept as
    1- Entity or Attribute,
    2- Entity or Relationship,
    3- Binary or Ternary Relationships


    Thanks
