ERD making tips

• Make a list of potential entities and attributes that scenario mentions
• Draw your entities and their relationships.(Do not forget relationship types!)
• If needed, consider using super and subtypes to handle some requirements of the scenario better.
• Give each entity their attributes and feel free to add extra ones to make your database more encompassing.
• Fix up any many to many types by adding composite entities.
• Read the given scenario again and make sure that your ERD handles all its requirements.
