This research paper focuses on how to prepare an effective data warehouse with the use of Requirements Engineering. Earlier operating systems used for storage of information, facilitated us in making only day-today decisions, because they provided us with only the current data, which cannot consider appropriate enough to involve significant conclusions. Thusly, it evoked the need of using Data Warehouse for storing all the information. Construction of efficient Data Warehouse and its

... involves extraction, cleaning and filtering of information etc. It is a costly and time-consuming procedure, because this has made in advance of the necessities to be met. To surmount this problem, such a technique should use, which will help in exploring and clarifying each requirement in particular having a meaningful consideration while constructing the Data Warehouse at an early phase. For this we have combined the technique "Requirement Analysis" of "Requirement Engineering" with the Requirement gathering techniques of Data Warehouse i.e. "Interview" and "Survey Method".
