1. Aggregation represents a "has-a" relationship where a whole is made up of parts that can exist independently.
2. Composition represents a "is-a" relationship where a whole is made up of parts that cannot exist independently.
3. Aggregation allows parts to belong to multiple wholes, while composition does not.
4. Aggregation typically involves softer relationships that can be easily broken, while composition involves stronger relationships that are more permanent.
