Abstract: -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.
