Figure 88 — Assignment to Group
The Assignment to Group established the assignment of an object to a group, being an arbitrary collection of objects. It is the complementary concept template to Group Assignment defining how object are assigned by a group.
The grouping relationship does not apply any other meaning then grouping objects under some aspect. It is non-hierarchical, meaning that objects can be assigned to many groups, and it does not interfere with other relationship concepts, such as Element Decomposition.
Figure 88 illustrates an instance diagram.
