This includes extracting data from various sources, transforming it into a usable format, and loading it into the warehouse for further use. Additionally, they develop and maintain database management systems, ensuring that the warehouses are optimized for performance and reliability. Regular monitoring and troubleshooting of data warehouse systems to identify and resolve any issues also fall under their purview.
