    Conceptual database designs is used to define the objects and relations between them. ER diagram is best suited for defining relation and there respective functions. This model is flexible enough to bear a change with out any harm to other data's structure. ER data base model represent association. which is needed to define relations.

    Logical database model is some what advanced of this model. In this model you need to define keys, attributes, behaviors and foregn keys to be inherit and possible representation which can be converted into physical data models. here we do not need association and other functionalities thats why we did not use ER diagrams.
