Identity
- Identity is the property of an object which distinguishes it from all other objects
- Many objects have unique attribute values such as names or id’s
- A U.S. citizen has a social security number and/or driver’s license
- An employee is distinguished by an employee id
- An automobile is distinguished by a license plate number
- The identity of an object is preserved even when its state changes
- Two objects can be identical in all properties, but still have different unique identifiers
