Abstract

A data warehouse is a global repository that stores pre-processed queries on data which resides in multiple, possibly heterogeneous, operational or legacy sources. The information stored in the data warehouse can be easily and efficiently accessed for making effective decisions. It is collection of decision support technologies. It is a subject oriented, integrated, time verifying, non volatile collection of data that is used primarily in organizational decision making. Data warehouse can be built using a top-down approach, bottom – down approach or a combination of both. In this research paper we are discussing about the data warehouse and design process.
