With the exponential growth of data in today\'s digital world, proper analysis has become crucial for extracting meaningful insights that enable predictive capabilities. These capabilities prove invaluable across industrial and business sectors for informed decision-making, risk assessment, and strategic planning. Big Data Analytics serves as the cornerstone of this process, employing specialized tools and techniques to handle massive, complex datasets characterized by volume, velocity, variety, veracity, and value. This paper examines the pivotal role of Big Data Analytics and its transformative impact across various domains. We focus on five powerful analytical tools - Hadoop, Spark, SAS, TensorFlow, and Tableau - each addressing distinct aspects of the data processing pipeline from storage and computation to advanced modeling and visualization. The study provides a comprehensive comparative analysis of these technologies, evaluating their architectural differences, performance efficiency, and real-world applicability in key industries including finance, healthcare, e-commerce, and artificial intelligence.
Introduction
1. What is Big Data?
Big Data refers to extremely large and complex datasets that cannot be managed with traditional analytical tools. It includes structured, semi-structured, and unstructured data generated rapidly in today’s digital world. To manage such data, organizations rely on Big Data Analytics for insight-driven decision-making.
The 5 Vs of Big Data:
Volume: Size of data (from TB to PB)
Velocity: Speed of data generation/processing
Variety: Different data formats (text, video, logs, etc.)
Veracity: Data quality and reliability
Value: Usefulness of insights derived from data
