While big data deals with large scale data, cloud computing deals with the infrastructure of the data storage. Big data streaming is a process in which large streams of real-time data are processed with the sole aim of extracting insights and useful trends out of it. patterns in stream data, Even store them in a compressed form, such as. Mining data streams is concerned with extracting knowledge structures represented in models and patterns in non stopping streams of information. Data Streams. - The primary goal of big data analytics is to help companies make more informed business decisions by enabling data scientists, predictive modelers, and other analytics professionals to analyze large volumes of transactional data, as well as other forms of data that may be untapped by more conventional Business Intelligence(BI) programs. In the big data mining framework, we need to consider the security of data, the privacy, the data sharing mechanism, the growth of data size, and so forth. No public clipboards found for this slide.
