A survey paper on big data analytics

In recent years, the internet application and communication have seen a lot of development and reputation in the field of Information Technology. These internet applications and communication are continually generating the large size, different variety and with some genuine difficult multifaceted structure data called big data. As a consequence, we are now in the era of massive automatic data collection, systematically obtaining many measurements, not knowing which one will be relevant to the phenomenon of interest. For example, E-commerce transactions include activities such as online buying, selling or investing. Thus they generate the data which are high in dimensional and complex in structure. The traditional data storage techniques are not adequate to store and analyses those huge volume of data. Many researchers are doing their research in dimensionality reduction of the big data for effective and better analytics report and data visualization. Hence, the aim of the survey paper is to provide the overview of the big data analytics, issues, challenges and various technologies related with Big Data.
