Automated data quality checks are essential for ensuring the integrity and reliability of data in various systems, particularly in data warehousing and database management. These checks can help identify and rectify data quality issues with minimal human intervention, thereby enhancing efficiency and accuracy.

Several tools and methodologies exist for implementing automated data quality checks. For instance, Large Language Models (LLMs) can be utilized to detect data errors by converting tabular data into plain text, allowing the models to analyze the data similarly to experienced human analysts. This approach leverages the extensive training of LLMs on diverse content, enabling them to identify potential errors intuitively and handle the inherent uncertainty associated with data quality issues ¹.

Moreover, various solutions like dbt tests, SQLMesh audits, and Monte Carlo aim to improve visibility into data quality issues and reduce incidents. However, successful implementation of these programs often requires a focus on process failures rather than merely addressing bad records ⁵. This holistic approach can lead to more effective data quality management.
