Context Diagram
From Event-B
The Context diagram defines the static (constant) part of a model. The context diagram is similar to a class diagram but has only constant data represented by ClassTypes, Attributes and Associations. Axioms (given properties about the constants) and Theorems (assertions requiring proof) may be attached to the ClassTypes. ClassTypes either define ‘carrier’ sets or constant subsets of other ClassTypes. ClassTypes may own immutable attributes and associations which represent constant functions that use the ClassType as domain.
