ABSTRACT
Data warehousing, as a technical discipline within information technology, has been evolving over the past 30 years and has emerged as fairly stable and mature only within the past decade. A key driver of this maturation is the development of large-scale database technologies that can handle the terabytes of data that a modern data warehouse is expected to hold. Without these technologies, today’s data warehouses wouldn’t be possible, and while the technical evolution continues, standardized models of large-scale data warehouses are emerging, and best practices are being identified.
