Introduction
Analysis of the core framework of the standard
GB/T40685-2021 has built a four-layer architecture of "strategy-goal-management domain-value realization", emphasizing the management concept of taking business as the main line and value as the orientation. The standard divides the management domain into three modules: management object, management process and management guarantee, forming a complete closed-loop system.
Comparison of key management processes
| Management process | Core requirements | Technical support | Output |
|---|---|---|---|
| Data asset confirmation | Use blockchain/electronic certification technology | Comply with GB/T33770.2 requirements | Proof of ownership registration |
| Data asset assessment | Quality + value dual-dimensional assessment | Refer to Appendix A method | Assessment report |
| Data asset audit | Full process compliance review | A traceability mechanism needs to be established | Audit report |
Implementation points
1. Data asset catalog construction
The standard requires the establishment of a four-dimensional information model including basic attributes, business elements, management elements, and value elements. A financial enterprise implementation case shows that the data retrieval efficiency can be improved by 40% through standardized classification (subject/theme/business).
2. Technical practice of property rights confirmation
It is recommended to use the
- Time attribute: timestamp service
- Identity attribute: digital certificate
- Content attribute: hash value evidence
Detailed explanation of evaluation method
Appendix A provides four evaluation methods:
- Market method: It is necessary to establish an adjustment coefficient system (quality coefficient 0.8-1.2, regional coefficient 0.9-1.1)
- Income method: The economic value discount rate is recommended to be 8%-12%, and the social value weight requires expert review
- Cost method: Including full cost accounting such as data collection, cleaning, and storage
- Comprehensive method: recommended weight ratio (cost method 30% + market method 20% + income method 50%)
Compliance requirements
The standard is linked to multiple regulations:
- Personal information protection: implement GB/T35273
- Data security: meet the classification requirements of GB/T37973
- Quality assessment: use GB/T25000.24 measurement indicators
