State Concept Structure Diagram
A state concept structure diagram assembles all information relating to the state concept diagram described. This diagram is initialized from concept diagram elements.
For example,
The diagram includes:
• variations between components
For example, "Subscriptions" can be classified by "Subscription Type". A "Subscription Type" being characterized by a "Loan Type".
A variation describes how a concept can be varied under another form. The variant is an object similar to the varied object, but with properties or relationships that may differ.
For more details, see Defining Inheritance of a Concept Component.• Substitutions between components
A substitution determines which element can be used to replace another, or is effectively replaced by an element existing in a given context (for example in the context of a variation). Unlike a variation, a substitution does not involve inheritance but a functional equivalence.For more details, see Creating a Concept Component Substitution.• Concept Information Items,
A sub-property is used to specify the relationship between two concept properties.For more details, see Concept Properties.• Concept components describing the relationship between two Concepts
For example, a "Subscription Type" is characterized by an "Available Loan Type".
A concept component enables representation of a dependency relationship between two concepts. This relationship is directional.For more details, see Concept Components.• start events, intermediate events and end events enabling definition of events contributing to change of state of a concept,
For example, the change of state of a member can be caused by a birthday.
An event concept represents an event occurring during concept life, for example a change of season. An event concept marks the impact on a concept of a phenomenon internal or external to the concept. Concept events can be distinguished as concept start events, end events and intermediate events.For more details, see Describing State Concepts.
