Introduction & Overview Schema validation ensures that data adheres to a predefined structure, format, and set of rules before it is processed, stored, or analyzed in a DataOps pipeline. It acts as a gatekeeper to maintain data quality, consistency, and reliability in data-driven systems. This tutorial provides an in-depth exploration of schema validation within the … Read more
Introduction & Overview What is Data Anomaly Detection? Data anomaly detection is the process of identifying patterns or data points that deviate significantly from expected behavior in datasets. These anomalies, often referred to as outliers, can indicate errors, fraud, or significant events requiring attention. In DataOps, anomaly detection ensures data quality, reliability, and trustworthiness across … Read more
Introduction & Overview What is Great Expectations? Great Expectations (GX) is an open-source Python-based framework designed for data validation, documentation, and profiling. It enables data teams to define “Expectations”—assertions about data properties—and use them to validate datasets, ensuring data quality throughout the DataOps lifecycle. By automating data testing and generating human-readable documentation, GX helps organizations … Read more
Introduction & Overview Data Quality Testing (DQT) ensures that data used in analytics, machine learning, and business intelligence is accurate, consistent, and reliable. In DataOps, a methodology that applies DevOps principles to data management, DQT is critical for delivering trustworthy data at speed and scale. This tutorial explores DQT’s role, implementation, and best practices within … Read more
Introduction & Overview What is Integration Testing? Integration testing verifies that individual modules or components of a data pipeline work together as expected. Unlike unit testing, which focuses on isolated functions, integration testing examines interactions between components, such as data sources, transformation logic, and storage systems, to ensure end-to-end functionality in DataOps. History or Background … Read more
