Data Quality In Data Engineering Workflows
Blog post from Datafold
Data quality testing is a crucial component in data engineering workflows, ensuring the accuracy and reliability of data used for business decisions, similar to how software engineers test applications. By integrating automated data testing within continuous integration and continuous delivery (CI/CD) frameworks, data engineering teams can maintain data integrity, reduce manual errors, and respond swiftly to data quality drifts. Tools like GitHub and CircleCI facilitate version control and automate testing processes, allowing for staging and production environment comparisons to be seamlessly conducted. Automated data testing, through tools like Great Expectations and dbt, enables data teams to enforce data quality gates, ensuring only validated data updates business intelligence dashboards. This automation not only enhances the efficiency of data workflows but also builds organizational trust in data-driven decision-making by preventing the propagation of inaccurate data.
