Data Quality Dimensions

The primary dimensions of data quality include:

• Accuracy: Data correctly represents the real-world entity or event
• Completeness: All required data elements are present and populated
• Consistency: Data values are uniform across different systems and time periods
• Timeliness: Data is available when needed and reflects current information
• Validity: Data conforms to defined formats and business rules
• Uniqueness: No duplicate records exist for the same entity

Data Quality Assessment Methods

Regular assessment of data quality involves systematic evaluation techniques:

Assessment Method	Purpose	Frequency
Data Profiling	Analyze data structure and content patterns	Initial and periodic
Data Auditing	Validate compliance with business rules	Ongoing
Statistical Analysis	Identify outliers and anomalies	Regular intervals
User Feedback	Capture end-user quality concerns	Continuous

Data Quality Improvement Strategies

Implementing effective data quality improvement requires a multi-faceted approach:

• Preventive controls: Input validation, data entry standards, and training programs
• Detective controls: Data monitoring, exception reporting, and quality dashboards
