Introduction

Analysis of the core framework of the standard

This standard has established a three-tier management system with the maintenance organization as the core, and clearly defines the collaborative division of labor between the management group and the technical group. Among them, the formulation and implementation of the technical review rules (Clause 4.2.3) are the key control points to ensure the quality of the data dictionary.


Data Dictionary Full Lifecycle Management

Phase Key Actions Responsible Entity Output
Addition Identifier Generation, Recording, and Release Notice Maintenance Organization Version Record (5.1.1)
Revision Data Item Replacement, Patch Release Technical Group Review Modification Notice (5.1.2)
Abolition Backup, Recording, and Deletion Notice Execution by the Management Group Archive Records (5.1.3)

Technical Innovation Analysis

The standard innovatively introduces the DMR (Data Maintenance Request) mechanism (Clause 3.4), which is implemented through the standardization application form in Appendix A/B:

  1. New categories need to submit the three elements of full name/abbreviation/definition
  2. Feature revisions need to clarify the value format/level/code technical parameters
  3. Dual-track approval process (formal review by the management group + substantive review by the technical group)

Implementation Suggestions

Suggested user units:

  • Establish a regular communication mechanism with maintenance agencies (4.2.1.e)
  • Regularly conduct data dictionary compliance self-assessment (Clause 5.4)
  • Prioritize the use of data map sharing method (Clause 5.3.2)
