The Importance of Data Testing in Data-Centric Projects | iceDQ Overview | Sandesh Gawande
In today's video, Sandesh, an industry expert with over 25 years of experience in data engineering, discusses the importance of data testing in the modern world of data-centric projects. With a focus on data migration, ETL testing, and big data, Sandesh highlights the crucial aspects of data testing that often go overlooked in traditional quality assurance (QA) processes.
Using the TSB Bank data migration failure as a case study, Sandesh explains how ignoring data testing during a migration project can lead to disastrous financial and reputational losses. He emphasizes the need for automated data testing tools like iceDQ and outlines the key differences between application testing and data testing.
