Sanskar Haritash

Abstract: Data Science now a days is being used in almost all the fields of IT and Computer Engineering. With the technological revolution, data went from expensive, difficult to find and collect to abundant, cheap, but incomprehensible. It is arduous to store, understand and analyze increasingly larger volumes of data with traditional software?s. This is where Big data comes into play. Big data is used for predictive analytics, analyzing user behaviour or other data analytics processes to bring value to data. This paper presents a research survey done in the field of Data Visualization Tools which ease the understanding of various data sets by representing them graphically or pictorially, no matter how big the data set is. Data Visualization is the process of transforming data into charts, images, graphs and even videos that explain the numbers and allow us to gain insights from it. Using Data Visualization tools in order to analyze the data is the new era of development. In this paper, three popular Data Visualization tools are taken into consideration, namely: Power BI by Microsoft, Tableau by Salesforce and Cognos by IBM. This research work provides knowledge about Data Analytics and aims to find out why Power Bi and Tableau are more popular in people whereas Cognos is not, and what advancements/changes do Cognos need in order to increase its reach.
