Etl development life cycle

                                                                                                                                         <<<            >>>
Hi,
To learn etl testing, sql is mandatory and should have knowledge in unix. Any way I will guide you in last section.

ETL Testing:-
ETL testing is similar to manual testing which we have to do manually with human interaction.

Once after inserting or updating the data into datamart by etl developer then we will test that datamart before loading into the centralized dataware house. This test is called ETL Testing.

 Etl development life cycle:

                                     
                    REQUIREMENT ANLAYSIS
                  
                    HIGH LEVEL DESIGN    

                    LOW LEVEL DESIGN

                    DEVELOPMENT
       
                    SIT(system integration testing)

                    REVIEW

                   TESTING--------->>Etl Testing life Cycle

                    UAT(user acceptance testing)

                   PRODUCTION
