* 의존관계
- has a ->Attribute    ex :  자동차 - 엔진         
                                                     - 타이어
   ->aggregation 부엌 - 냉장고(부엌이 만들어 질때 부품들이 채워져 있지 않고 나중에 조금씩 채운다. (life cycle이 같지 않아도 된다.)
   ->composition - 생성될 때 다 같이 생성되야 한다.(부엌이 만들어 질때 부품들이 채워져 있어야한다.)(life cycle이 같아야 한다.)
        
- use a ->메소드 -사용하고 나면 없어지는것.

* has a 관계 ( 의존 관계 )
