When will I have access to the lectures and assignments?

To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.

What will I get if I subscribe to this Specialization?

When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.

Is financial aid available?

Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.

您将学到什么

Systematic testing with unit, schema, and data checks builds reliable data systems and prevents costly downstream errors.
Recursive CTEs make hierarchical data queryable, enabling analysis of org charts, product trees, and complex structures.
Scalable data validation requires automation, as manual testing cannot meet modern data engineering demands.
Hierarchical data exists across industries, and recursive queries offer transferable skills for data-driven teams.

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.
