....A simple hierarchy for part relationships Part relationship is the relationship studied in Section 2.1. The same composite can be related to several components. For instance, a newspaper can be composed of editorials, articles, and pictures (see Figure 1(b) Part association, thus named after [2], specializes part relationship by relating a composite to a collection of components of the same class. In other words, a part association models the case where a class participates as a composite in a single binary part relationship. For example, in Figure 2(a) a compilation is composed of ....

....for dynamic schema modi cation needs, only one aggregation, in which a composite class can participate, is represented, this aggregation is said partial. As shown by Figure 6, a partial aggregation can always become total by relating the composite class to a component class others. Association [5] specializes aggregation and relates a composite object to a collection of components of the same nature. Hence, all component objects belong to the same class. Recursion specializes association since components but also composites are objects of the same nature thus objects belonging to the same ....
....belonging to the same class. Control structures applied to these three abstractions allow us to formally distinguish them in object design which is the development step providing a design model based on the object model but containing implementation details. The ACM PCM modeling methodology [5] already di erentiates association from aggregation using control structures but only in a behavioral view. Viewed as a highest level control structure, a method invoked from a composite object and operating on aggregations, in which this object participates, will be implemented by a sequence. ....
