Use case diagrams or data flow diagrams are often used for the documentation of the system contexts (especially the system and context boundaries). In context modeling, based on data flow diagrams, the sources and sinks in the system environment are modeled, showing respectively the source or destination of data flows between the system in consideration and the environment. The actors (i.e. for example people or other systems) in the system environment and their use relations with the system to be developed are modeled inuse case diagrams.
According to the sylabus class diagrams are also used to document the system context.
