PhysicalDataSet

Is Abstract: 
no
Is Pattern: 
no
Definition: 

The information needed for understanding the physical structure of data coming from a file or other source. A StructureDescription also points to the Data Store it physically represents.

Explanatory Notes: 

Multiple styles of structural description are supported: including describing files as unit-record (UnitSegmentLayout) files; describing cubes; and describing event-history (spell) data.

Example: 
The PhysicalDataProduct is the entry point for information about a file or other source. It includes information about the name of a file, the structure of segments in a file and the layout of segments.

A physical description of the data store encompasses a description of its gross record structure. This structure consists of one or more PhysicalRecordSegments and their relationships. Allows for the identification of the member and optionally provides an index for the member within an ordered array
isOrdered
0..1
If members are ordered set to true, if unordered set to false.
type
0..1
Whether the dataset is a bag or a set: a bag is a collection with duplicates allowed, a set is a collection without duplicates.
