Therefore, it is necessary to study both the inheritance and the relationship diagrams to understand the functionality of individual packages. In simple sub models these are shown in the same diagram but are omitted from the more complex sub models for the sake of clarity. In these cases, the inheritance diagram below shows the full inheritance tree for the classes concerned with data structure definitions.
