概要
Data Quality Frameworks provides a comprehensive set of implementation patterns for establishing a robust testing layer across the entire data lifecycle. It guides users through the data testing pyramid, covering everything from basic schema validation to complex statistical checks and cross-table integration tests. By utilizing industry-standard tools like Great Expectations and dbt, the skill helps teams define clear data contracts, automate quality monitoring, and prevent downstream breakages. It is particularly useful for data engineers looking to formalize their validation logic and maintain high-fidelity datasets in production environments.
