Logical Model: Tabular View Definition

A profile for View Definitions where each resulting field must contain only a simple scalar value. This is sometimes referred to as 'CSV Mode', but applies to any system that explicitly constrains its views or tables to tabular data.

Usage:

• This Logical Model is not used by any profiles in this Implementation Guide
