Jean Cochrane enhanced data quality in the ccao-data/data-architecture repository by refining duplicate detection for sales data within dbt views. Focusing on the vw_pin_sale and vw_pin_sale_combined views, Jean tuned detection thresholds and aligned associated tests to reduce noise and improve the reliability of sales metrics used in analytics and reporting. This work involved careful data modeling and database configuration, leveraging YAML and dbt to ensure that test coverage matched production standards. By strengthening data governance and continuous integration practices, Jean’s contributions provided more accurate, auditable sales data, supporting better decision-making and maintaining high standards for data reliability and testing discipline.
