    Hai hajvery,

    Seems like u want

    1 - A business case where the business needs a RDBMS and you have to come up with the UoD (Universe of Discouse) and Information Requirements

    2 - The Conceptual Model in ERD

    3 - And you may or may not need the Logical Model.

    I suggest that you get some Logical models and build your case around it. See these models.

    http://www.databaseanswers.org/data_models/index.htm

    Just pick any model and build your case around it. In actual pratice it is done the other way around.

    If you want an ERD try this

    Sounds to me like you're in the wrong class, my friend.
