ETL Testing and Its Importance Introduction to ETL Testing ETL (Extract, Transform, Load) testing is a crucial process in data warehousing and business intelligence. It involves validating, verifying, and ensuring that the data extracted from different sources is correctly transformed and loaded into the target database or data warehouse. The primary goal of ETL testing is to ensure the accuracy, completeness, and reliability of data before it is used for analysis and decision-making. Components of ETL Testing Extract: Data is retrieved from multiple heterogeneous sources such as databases, flat files, cloud systems, and APIs. Transform: Extracted data undergoes transformations such as cleansing, validation, aggregation, and formatting to meet business requirements. Load: The transformed data is then loaded into the target database, data warehouse, or any other storage system for reporting and analysis. Importance of ETL Testing ETL testing is vital for organizations relying on data-d...

Performance Testing: An Essential Practice in Software Development Introduction Performance Testing is a critical aspect of software testing that evaluates how a system behaves under various conditions.
