BIG DATA ANALYTICS: TECHNIQUES AND APPLICATIONS

Abstract

Abstract - Big Data Analytics has emerged as one of the most transformative technologies of the digital era, enabling organizations to extract meaningful insights from massive volumes of structured, semi-structured, and unstructured data. The rapid growth of digital technologies, social media, cloud computing, the Internet of Things (IoT), mobile devices, and artificial intelligence has resulted in an unprecedented increase in data generation. Big Data Analytics employs advanced analytical techniques, machine learning algorithms, statistical methods, and distributed computing frameworks to process, analyze, and visualize large datasets for informed decision-making. It has found extensive applications across healthcare, finance, education, manufacturing, retail, transportation, agriculture, cybersecurity, and smart cities. Despite challenges such as data privacy, security, integration, scalability, and data quality, Big Data Analytics continues to drive innovation, improve operational efficiency, and support strategic decision-making. This paper discusses the concept, characteristics, architecture, techniques, tools, applications, benefits, challenges, and future trends of Big Data Analytics.
