ETL Testing Training provided by IdesTrainings will be an added advantage for your carrier. ETL means extracting the data, transforming the data and then loading the data from one system to other system. To extract means pulling or getting the data from source system to whatever for record tables and transform the simple word converting one form to another form, transforming in to another form based on our requirement and loading into the target table and extracting process.
