Logical Model: QTY - Detailed Descriptions

Definitions for the QTY logical model.

1. QTY

is an abstract generalization for all data types (1) whose value set has an order relation (less-or-equal) and (2) where difference is defined in all of the data type's totally ordered value subsets. The quantity type abstraction is needed in defining certain other types, such as the interval and the probability distribution.

2. QTY.nullFlavor

If a value is an exceptional value (NULL-value), this specifies in what way and why proper information is missing.

BindingThe codes SHALL be taken from NullFlavor
