Abstract
This chapter introduces the basic concepts of data warehouses. A data warehouse is a particular database targeted toward decision support. It takes data from various operational databases and other data sources and transforms it into new structures that fit better for the task of performing business analysis. Data warehouses are based on a multidimensional model, where data are represented as hypercubes, with dimensions corresponding to the various business perspectives and cube cells containing the measures to be analyzed.
