ETL Testing Course Syllabus
Our ETL Testing Course Syllabus gives the learners an in-depth knowledge on emphasizing analysis of data, cleaning bad data in the source system, creating multiple tests for data validation, finding an ETL tool that supports the data sources, monitoring ETL jobs, and dealing with a full scale of ETL Testing. Our ETL Syllabus is helping students to write a testing process to ensure that the data has been loaded from a source to destination after the business transaction is accurate.
