Version & Date

Version 3.0

See NAF Release History.

Purpose

From the NATO Architecture Framework v3, CHAPTER 4, Section 4.7.10.1

The purpose of distinguishing logical from physical data models can be found in the fact that logical models allow analysis of a system’s data definition aspect, without consideration of implementation specific or product specific issues.

Another purpose is to provide a common dictionary of data definitions to consistently express subviews wherever logical-level data elements are included in the descriptions.

Covered by NATO release conditions.

Definition

From the NATO Architecture Framework v3, CHAPTER 4, Section 4.7.11.1

The logical data model is a generalized formal structure in computer science. As such it directly reflects the paradigm or theory oriented mapping from the information model to the data model. The most predominant of such mappings are the ones reflecting relational calculus (entity-relationship-attribute) and object-orientation (class-object-method-property).

Covered by NATO release conditions.


From the NATO Architecture Framework v3, CHAPTER 5, Section 5.2.6.11

The data in an NSV-11a can include:
• Operational Information Entity

Note that an Operational Information Entity within an NSV-11a may be an Information
Element in an NOV-3 or an Activity Flow Object in an NOV-5.


Covered by NATO release conditions.
