Abstract

The emergence of big data presents opportunities as well as challenges in deriving meaningful insights for enhanced decision-making. This paper provides a comprehensive overview of the data preparation, transformation, and visualization techniques used in big data analytics. We first introduce the properties of big data and the analytics process. Next, we discuss data preparation tasks like data cleaning, integration, reduction, and transformation. Data mining, statistical learning, and machine learning techniques used for analysis are examined. The role of visualization techniques like charts, plots, dashboards and interactive visual analytics in discovering patterns, trends and outliers is explained. Example implementations of data preparation, analytics and visualization methods using tools like Hadoop, Spark, R and Python on real-world big data are provided. We also discuss challenges and research directions in areas like scalable, real-time and secure analytics over big data. This paper serves as a valuable reference on the end-to-end process of extracting insights from big data.
