Data Mining and Warehousing PPT And Seminar Presentation

A modern reporting environment will give users access to their data, but it doesn’t solve all their problems. Just because users have access to data doesn’t guarantee the integrity of that data. Nor does it guarantee that system response times will be adequate. It doesn’t guarantee that the users system won’t purge old data before its useful life is passed. Data warehousing and data mining can address the above problems and provide a technology that enables the decision-maker to process this huge amount of data in a reasonable amount of time and to extract intelligence/knowledge in a near real time.  A data warehouse is a database of data gathered from many systems and intended to support management reporting and decision-making. But users such as companies want to “mine” that data for other purposes (particularly for sales, marketing etc.,). So data mining techniques are employed for extracting new insight from the data warehouse.
