Editor's Notes
- #17 1.
- #18 An aggregation is a stronger form of relationship where the relationship is between a whole and its parts. The aggregate has an aggregation association to the its constituent parts. A hollow diamond is attached to the end of an association path on the side of the aggregate (the whole) to indicate aggregation. Since aggregation is a special form of association, the use of multiplicity, roles, navigation, etc. is the same as for association. Sometimes, a class may be aggregated with itself. This does not mean that an instance of that class is composed of itself (this would be silly), it means that one instance if the class is an aggregate composed of other instances of the same class. Some situations where aggregation may be appropriate: An object is physically composed of other objects (e.g. car being physically composed of an engine and four wheels). An object is a logical collection of other objects (e.g., a family is a collection of parents and children). An object physically contains other objects (e.g., an airplane physically contains a pilot). In the above example, the relationship from Student to Schedule is modeled as an aggregation because a Schedule is inherently tied to a particular Student. A Schedule outside of the context of a Student makes no sense in a Course Registration System.
- #19 Composition is a form of aggregation with strong ownership and coincident lifetimes of the part with the aggregate. The whole “owns” the part and is responsible for the creation and destruction of the part. The part is removed when the whole is removed. The part may be removed (by the whole) before the whole is removed. A solid filled diamond is attached to the end of an association path (on the “whole side”) to indicate composition. In some cases, composition can be identified as early as analysis, but more often it is not until design that such decisions can be made confidently. That is why composition is introduced here rather than in Use-Case Analysis.
