The Graph Tool
provides the
functionality to access, view and modify modeling language specifications at the
graph level (e.g. specifications of the Family Tree diagram technique and its
elements). From this tool you can also open the other metamodeling tools on a
graph type’s components, e.g. open an Object Tool on an object type used
in this graph type.
Figure 2–6. Graph Tool.
The difference between the
Graph Tool and other metamodeling tools (Object, Relationship, and Role tools)
is that where the others handle individual components of a modeling language,
the graph tool connects these pieces together to form the modeling language. The
components are managed by the various other tabs of the Graph Tool window:
Types, Bindings, Subgraphs and Constraints.
