Get the right foundations and focus on the principles of data warehouse architecture. “The datawarehousing toolkit” by Ralph Kimball is a great guide to start with towards traditional datawarehouse design. Understand the differences between Transactional , analytical Dataware houses, general database principles, data integrity rules,standards and their real time implementations.
