in this paper, the authors focus on what they can do through warehouse builder, that is, performance configuration setting during ETL and schema design. Tips on configuring their database for optimized performance, they focus mainly on specific warehouse builder performance-related features to achieve optimal performance. They live in a dynamic world, in a permanent move, were performance of information systems continually increases. Thus, the need of being informed, regardless of place or time, is very great using data warehouses solutions. Therefore, the need for efficient information systems is very high. The efficiency can be achieved by using various methods/techniques and technologies “To build” the data warehouse.
