Role A
|
One side of a node association. Each role can have a name and a cardinality and be navigable.
|
|
Node A
|
Name of the node at one end of the node association. You can use the tools to the right of the list to create an object, browse the complete tree of available objects or view the properties of the currently selected object.

Multiplicity A
|
Multiplicity indicates the maximum and minimum number of instances of the node association. You can choose between:
-
0..1 – zero or one
-
0..* – zero to unlimited
-
1..1 – exactly one
-
1..* – one to unlimited
-
* – none to unlimited
For example, in a computer environment, there can be 100 clients and 100 machines but there is a constraint that says that a machine can accept at most 4 clients at the same time. In this case, the maximum number of instances is set to 4 in the Multiplicity box on the machine side:
