This course includes why ETL testing is the need of the time and how a software tester verify the data efficiency w.r.t the transformation. How normal DBs are not helpful in this case and ETL processes being inplemented to support the decission making system and final report generation in a very simple apprach. In data warehouse we can manage the structural and semistructural data and process that by ETL. ODS, DM and Enterprise data warehouses are used mostly to manage the data here.
Note: Any one can opt ETL testing as a carrier with little understanding of SQL, Software testing, any ETL tools etc. Believe me you can do it.I will help you to make it happen. All etl testers can now learn Big data and need to learn how Structural, semistructural and Non Structural data can be managed by ETL and Big Data.If interested please go for a demo so that i can clarify your doubts and you can choose a better carrier.
