ETL Testing

As part of ETL Testing, we are responsible for validating data sources, extracting data applications of transformation logic, and uploading data in target tables. We are responsible for designing, testing, and troubleshooting the company's data storage system before it goes live. We have strong technical capabilities and good knowledge of the coding languages commonly used in ETL development, such as Java, SQL, XML. Familiarity with data warehouse architecture techniques like ODS, DM, EDW, M, and ROLAP is also needed. Employers or clients often prefer ETL developers with extensive experience in solving complex technical problems and troubleshooting.
