In Object-oriented design, association is a relation between two objects, for example, Car & Wheel have an association (that is, car contains wheels), Toolbar & Button have an association (that is, toolbar is composed of buttons), a Student is associated to Course (that is, a student can study a course). It can be strong association or weak association. If A is strongly associated to B then A cannot exist without B. In implementation terms, object A would be composed of object B & without creating B, creation of A is not possible. For example, a Toolbar cannot be created without creating a Button. If A is weakly associated to B then A can exist without B. For example, a Student can exist without the exitence of Course.
