Today, more then ever, data is central to any organization to provide useful insights and competitive advantages. There is also a growing need to move data around, from one database to another or within schemas of the same database, for better analysis, testing, and review. Data warehouses are crucial for predictive analysis, and the need to have efficient tools to extract, transform, and load data in these environments is extremely important.
