ETL Developer
The ETL Developer designs and deploys the process by which source data is extracted, transformed, and then loaded to the target data warehouse. Since the majority of project risk and effort is involved with this step, it is crucial that the previous development phases are carried out with a high degree of quality. It is essential for the ETL Developer to have a strong understanding of the source data, the needed transformations, and star schema design from the very beginning of ETL development.
