PhysicalDataSetStructure

Generalization is Identifiable.

Superclass hierarchy

Definition

Ordering for physical record segments, which map to a logical record.

Examples

Explanatory notes

The same LogicalRecordLayout may be the sourceMember in several adjacency lists. This can happen when PhysicalRecordSegments are also population specific. In this instance each adjacency list associated with a LogicalRecordLayout is associated with a different population.
