Big data refers to a collection of information that is too vast and complex to be effectively collected, processed and analyzes using traditional algorithms, tools and approaches. In order to utilize big data, researchers, business and governments are focusing efforts on datasets characterized by three challenges, volume, velocity and variety. These challenges requires research and innovation at all levels of computing, from the physical networks needed for capturing and transporting such data to advanced algorithms for effectively, securing, organizing, processing and ultimately, making effective use of such data.
