Characteristics for attributes are also called properties. So every entity must have attributes to help make it unique. Behavior is important because the entity responds to other entities. For example, a person entity inserts a credit card into an ATM entity; the ATM entity responds with an action. The person will react differently depending on what the ATM does (reject or accept the credit card). What are at least three other examples of behaviors for other entities?
