Chapter 6 Building Implementation Diagrams

Node association property sheet General tab

The General Tab contains the following properties:

Property Description
Name The name of the item which should be clear and meaningful, and should convey the item's purpose to non-technical users.
Code Specifies the technical name of the object, which is used for generating code or scripts.
Comment Descriptive comment for the node association.
Stereotype Extends the semantics of the object beyond the core UML definition.
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.
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:
Role B One side of a node association. Each role can have a name and a cardinality and be navigable.
Node B Name of the node at the other end of the node association.
Multiplicity B Multiplicity indicates the maximum and minimum number of instances of the node association. For more details, see Multiplicity A, above.
