Interaction Diagrams and Specifications

Interaction Diagram Overview

An interaction is an important sequence of interactions between objects. Rational Rose provides two alternate views or representations of each interaction--a collaboration and sequence diagram. These are collectively referred to as interaction diagrams. The main difference between sequence and collaboration diagrams is that sequence diagrams show time-based object interaction while collaboration diagrams show how objects associate with each other.

You can specify and modify an interaction with either kind of diagram, or with both. Rational Rose automatically reflects all changes made either to a sequence or collaboration diagram in the corresponding collaboration or sequence diagram, if one has been created.
