Feature ETL Testing Database Testing
Focus Ensures proper data extraction, transformation, and loading from source to destination Validates data integrity, consistency, and accuracy within a database
Process Verifies data movement from multiple sources to the target data warehouse Checks CRUD operations (Create, Read, Update, Delete) within a database
Data Handling Deals with large-scale data from multiple sources and ensures correct transformation Works with structured data within a single system
Validation Data completeness, transformation rules, and performance of ETL workflows Schema validation, table structures, constraints, and indexing
Testing Tools Informatica, Talend, DataStage, SSIS, Hadoop SQL, Oracle, MySQL, PostgreSQL
Business Impact Ensures accurate data for analytics and reporting Ensures correct data storage and retrieval for applications

While ETL Testing is crucial for validating data migration, transformation rules, and business intelligence applications, Database Testing focuses on maintaining data accuracy and integrity within a single database system.
