Business intelligence is the technology that companies such as Amazon.com and Google use to take advantage of the enormous amount of data they collect and analyze. It is the technology with which Amazon.com knows what book to recommend you every time you login, Google knows how to rank the pages you are searching for, and banks decide whether to approve loan applications almost instantly. As organizations increasingly have to deal with ?big data,? the number of job openings and the need for skilled professionals in this field will continue to increase.
