UML provides an abstract representation of complex
relationships. This notation can be used to extend the
efforts of social and technical investigations by providing
a flexible and powerful communication framework.
UML is a compilation of primarily three common, yet
distinct notations (including OMT [Rumbaugh], Booch
& OOSE [Jacobson]), and is now a fully recognized and
published standard (ISO/IEC 19501:2005) within the
International Organization for Standardization (ISO).
SYSTEM MODELLING
Structuring information is critical in facilitating highly
dynamic and complex interactions. For raft guide trainees,
structure is provided continuously through direct
supervision. This instruction and supervision provides
guide trainees with valuable feedback and insight into
community practices and expectations. This feedback
allows guide hopefuls to develop and contribute to the
completion of a safe and enjoyable rafting experience.
By clearly communicating how raft guide trainees can
contribute to the professional rafting community, trainees
can offer valued contributions without imposing on
the guests’ experiences.
Rafting companies provide much more than professional
guides; they provide a carefully choreographed
series of experiences designed to educate and entertain.
The services must work to attain the highest quality
guest experience.
The experience attained within a digital community
can also be viewed as a series of choreographed and sequenced
interactions. These interactions are influenced
by both the architectural design of the digital community
and the services provided by information managers
during the implementation of the system architecture.
The development of modelling tools have been successfully
used to mediate these complex relationships, allowing
individuals to communicate important system
design information, system implementation processes,
and the sequences and activities available for facilitating
participation.
Use case diagrams
“The most important role of a use case model is
one of communication. It provides a vehicle used
by the customer or end users and the developers to
discuss the system's functionality and behavior.”
(Quatrani, 2003).
Describing how users will interface with highly structured
computer information systems is an important
and complex task. Developing technological infrastructure
that efficiently models community practices re-
