In Chapters 3 & 4, we learned about Entity-Relationship (ER) Models and Enhanced Entity-Relationship (EER) Models, and how they can help with designing a database. Think of a time (that's not school-related) that you or something you own as part of a database. In the context of that database, what kind of entity type were you/it? Give an example of a simple, composite, and multi-valued attribute you/it had.
