Data quality is a crucial aspect of ensuring the accuracy and reliability of information. To improve data quality, it is essential to consider four key entities: data accuracy, data completeness, data consistency, and data timeliness. Data accuracy measures the correctness and precision of data, ensuring that it accurately represents the information it intends to convey. Data completeness refers to the absence of missing values, ensuring that all necessary data is present for analysis. Data consistency ensures that data is consistent across different sources and time periods, preventing contradictions and inconsistencies. Finally, data timeliness measures the currency of data, indicating how up-to-date the information is. By addressing these entities comprehensively, organizations can significantly enhance the quality of their data, leading to more accurate insights and informed decision-making.
Discuss the key processes involved in data quality management, including data governance, data management, and data integration.
