Managing Interactions
An Interaction represents the exchange of information between organizational entities of the system.
Content of an interaction is described by an exchange contract.
For more details, see chapter "Describing Interactions", page 49. In the context of complex infrastructures, interactions are physically supported by communication channels. See Communication channels.
Creating an Interaction
To create an interaction:
1. In the resource architecture diagram objects toolbar, click Interaction 
.
.2. Draw a link between the two communication entities.
3. In the add interaction dialog box, specify the protocol you wish to use.
4. Click OK.
Connecting interaction points
The interaction point connects an interaction to one of the components in communication. It enables specification of:
• the service point or query point that intervenes in the communication.
• the role, consumer or supplier, played by the interaction point in the exchange protocol.
To connect the interaction point:
1. Right-click the interaction beside the communication entity and select Connect > Interaction Point.
A dialog box opens, presenting the list of service points and request points of the component in communication.
2. Select a service point or request point.
3. Click OK.
The graphic representation of the interaction point gives indications on nature and and consistency of information entered.
