Data Quality
The measure of data fitness for its intended purpose. High-quality data is accurate, complete, consistent, timely, and valid. Critical for AI systems that learn from data.
In-Depth Explanation
Data quality measures how well data serves its intended purpose. For AI and analytics, poor data quality leads to poor outcomes - "garbage in, garbage out."
Data quality dimensions:
- Accuracy: Data reflects reality
- Completeness: Required data is present
- Consistency: Data agrees across sources
- Timeliness: Data is sufficiently current
- Validity: Data conforms to rules/formats
- Uniqueness: No unwanted duplicates
Data quality issues:
- Missing values
- Duplicate records
- Inconsistent formats
- Outdated information
- Invalid entries
- Broken relationships
Quality improvement approaches:
- Data profiling (understand current state)
- Validation rules (prevent bad data)
- Cleansing processes (fix existing issues)
- Monitoring and alerting
- Root cause remediation
Business Context
Data quality directly impacts AI accuracy and business decisions. Organisations spend 15-25% of revenue dealing with data quality issues.
