As companies consider their ability to manage the asset that is information, the data warehouse platform (and its database management system or DBMS) is the most important decision point. The platform is the foundational component of the tool selections, the consultancy hires, the architecture, etc. In short, it defines your information culture.
However, in selecting the platform to support the data warehouse, organizations are faced with an exponentially higher number of variations and distinct departures from the traditional online transactional processing (OLTP) database management systems than ever before.
Over time, data warehouse data volumes will continue to soar as organizational history accumulates, syndicated data is collected and new sources with more detailed data are added. Furthermore, the community consuming the data continues to grow, expanding well beyond company boundaries to customers, supply chain partners and even users on the Internet. Companies need to make sure they choose a proven platform not just for the initial known requirements but also one with the ability to scale to future, to-be-determined requirements.
