InstanceVariableRelationStructure

Definition

A realization of RelationStructure that is used to describe the order of InstanceVariables in a record for those cases where the variables have a more complicated logical order than a simple sequence.

Synonyms

An information model, a struct in C, a nested object in JSON

Explanatory notes

For a simple sequence the order can be defined by the index values of the LogicalRecord’s InstanceVariableIndicators that a UnitDataRecord inherits. Alternatively, the InstanceVariableRelationStructure can be used by a UnitDataRecord to describe a StructuredCollection as needed.
