In today’s data-driven economy, companies rely on massive amounts of information to make critical business decisions. But what happens if that data is wrong? That is where you come in. ETL (Extract, Transform, Load) Testing is one of the most high-demand skills in the software testing industry, sitting at the intersection of Data Science and Quality Assurance.

This course is designed to take you from a complete beginner to a confident Data Warehouse Tester. We start by demystifying the architecture of Data Warehouses, explaining how data moves from diverse source systems into a unified repository. You will learn the "bread and butter" of ETL testing: Source-to-Target Mapping, where you will verify that every piece of data is transformed correctly according to business rules.
