What is Data Quality?
Data quality refers to the overall accuracy, completeness, consistency, and reliability of data. It measures the degree to which data meets the requirements and expectations of its intended use. High-quality data is reliable, relevant, and free from errors or inconsistencies.
Here are some key aspects of data quality:
- Accuracy: Data accuracy refers to how closely the data reflects the true values or facts it represents. Accurate data is free from errors, omissions, or mistakes.
- Completeness: Data completeness measures the extent to which all required data elements are present and populated. Complete data contains all the necessary information without any missing values.
- Consistency: Consistency refers to the coherence and uniformity of data across different sources or data sets. Consistent data maintains the same meaning, format, and values across various systems or databases.
- Timeliness: Timely data is up-to-date and reflects the current state of the information it represents. Outdated or delayed data may lose its relevance and affect decision-making processes.
- Validity: Valid data adheres to predefined rules and constraints. It satisfies the defined data models, formats, and standards. Validity ensures that data is fit for its intended purpose.
- Integrity: Data integrity refers to the accuracy and reliability of data throughout its lifecycle. It ensures that data remains intact, consistent, and unaltered, preventing unauthorised modifications, deletions, or corruption.
- Uniqueness: Uniqueness measures whether each data record or entity is represented only once within a dataset. It prevents duplicate account creation or redundant entries, which can distort analysis and lead to inaccurate results.
- Relevance: Relevance evaluates the usefulness and significance of data in relation to the goals and requirements of the intended use. Relevant data is directly applicable and contributes to meaningful insights and decision-making.
