Data warehousing in the age of big data

摘要

Over the last 25 years, there have been significant changes in the capture, processing, dissemination, analysis, and use of information. This transformation has not only affected how we do business, but has also impacted the underlying techniques and technologies that make business possible. For example, the relational model that stores traditional business transactions is no longer adequate to meet the storage and manipulation challenges of such information. This book argues that big data, with its three key dimensions of volume, velocity, and variety, presents a challenge that data analysts can't ignore.
