Example of a system context diagram. [1] A system context diagram in engineering is a diagram that defines the boundary between the system, or part of a system, and its environment, showing the entities that interact with it. [2] This diagram is a high level view of a system. It is similar to a block diagram.
A system context diagram represents the context graphically.. Several examples of context models occur under other domains. In the situation of parsing a grammar, a context model defines the surrounding text of a lexical element. This enables a context sensitive grammar that can have deterministic or stochastic rules.
The context diagram serves the purpose of "establish[ing] the information boundary between the system being implemented and the environment in which the system is to operate." [1] Further refinement of the context diagram requires analysis of the system designated by the shaded rectangle through the development of a system functional flow block ...
The objective of a system context diagram is to focus attention on external factors and events that should be considered in developing a complete set of system requirements and constraints". [15] System context diagrams are related to data flow diagram, and show the interactions between a system and other actors which the system is designed to ...
The problem context contains the machine and the application domain. The machine interface is where the Machine and the application domain meet and interact. The same situation can be shown in a different kind of diagram, a context diagram, this way:
A diagram is a partial graphic representation of a system's model. The set of diagrams need not completely cover the model and deleting a diagram does not change the model. The model may also contain documentation that drives the model elements and diagrams (such as written use cases). UML diagrams represent two different views of a system ...
A concept map or conceptual diagram is a diagram that depicts suggested relationships between concepts. [1] Concept maps may be used by instructional designers , engineers , technical writers , and others to organize and structure knowledge .
Contextual design uses the User Environment Design (UED) diagram, which displays the focus areas, i.e., areas which are visible to the user or which are relevant to the user. Focus areas can be defined further as functions in a system that support a certain type or part of the work.
