摘要：As we all know that implentation of a data warehouse requires a huge monetary investment. In this paper we studied the ROI for a particular data warehouse. The purpose of this paper is to calculate the Return on Investment on a data warehouse which has been designed using the concept of bottom up architecture and top down implementation. This paper compares the said design with other designs and we have shown that the ROI is better in case of the design discussed in this paper.
