Validate, Test, and Traverse Your SQL Data
About this course
Did you know that poor data quality costs organizations an average of $15 million annually? This Short Course was created to help data engineers and analysts accomplish bulletproof data validation and hierarchical data navigation. By completing this course, you'll be able to implement comprehensive testing suites that catch data errors before they impact downstream systems and create sophisticated recursive queries that unlock organizational hierarchies and complex relationships. By the end of this course, you will be able to: - Evaluate data transformations by implementing unit, schema, and data quality tests - Create recursive Common Table Expressions (CTEs) to traverse hierarchical data This course is unique because it combines rigorous testing methodologies with advanced SQL techniques that mirror enterprise data engineering practices, giving you production-ready skills for building trustworthy data systems. To be successful in this project, you should have a background in intermediate SQL, data modeling concepts, and experience with data transformation workflows. Transform your data engineering capabilities with enterprise-grade validation and hierarchical querying techniques that ensure data reliability and unlock complex organizational insights.
