Big data is the paradigm that refers to the data generated not only in
terabytes, but in hexabytes and more. Big data has gained an enormous success in
numerous application areas including social media, economy, finance, healthcare,
agriculture, and many more. Now a days, data are being produced at lighting speed. Data
produced in many media are either structured, unstructured or semi-structured, using
which the researchers could find the unknown pattern behind these datasets. Big Data is
one of the most important applications in parallel and distributed systems. Processes
related to analysis are often carried out with a deadline and during the process, it is vital
for analytics also to concern about the quality of the data. This paper highlights few
platform and tools used in the data analytics process. Further, it explains about the several
challenges faced in big data analytics. Data representation, data management, data
confidentiality and few other are found to be the major challenges in big data analytics.
Also, the paper aims to study the technologies applied for big data analysis in the fields
of cloud computing, Internet of Things and Hadoop. Finally, the paper reviews on the
key application areas of big data analytics by researchers.
