摘要：Today’s reporting environment give users to access their data, but it does not solve all the problems of user. The users have privilege to access the data but do not guarantee the integrity of the data and adequacy of response time.

With the help of data warehousing, user extract the knowledge in a real time and its help the user in the decision making. Many companies want to use that data for other purposes. So data mining techniques are evolved for extracting new knowledge from data warehouse. Data warehousing and data mining provide the right foundation for building decision support and executive information system tools which help to measure the progressing speed of organization toward its goal. Data warehousing and data mining provide a technology that enables the user or decision-maker in the corporate sector/govt. to process the huge amount of data and make decisions which are useful for whole organisation. This paper tries to explore the overview, advantages and disadvantages of data warehousing and data mining with suitable diagrams.
