There is no doubt that information is the most precious commodity for any business. Data is the new gold. Data is information in raw format, while information represents data after processing and analysis. There is data everywhere. We produce a massive amount of data each day through every click on the Internet, every bank transaction, every video we watch on YouTube, and every email we send. The increasing amount of data raises both the opportunities and the challenges of managing it. Today's organizations depend on data and insights to make most of their decisions. This huge trove of data is now presented under the umbrella term "big data."

Big data refers to extremely large and complex datasets that exceed the processing capacity of traditional data management systems. It is a combination of structured, semi-structured, and unstructured data that organizations collect, analyze, and mine for information and insights. Big data comes from many sources, including transaction processing systems, customer databases, documents, emails, medical records, Internet clickstream logs, mobile apps, and social networks. It has gained significant popularity and application in various industries, including finance, architecture, pharmaceuticals, telecommunications, transportation, supply chain, media and entertainment, oil and gas, space exploration, maritime industry, and the military.

This book is an extension or supplement to a former book, where 16 applications of big data are covered. In this book, we cover additional 11 big data applications. This is a must-read book for anyone who wants to learn about the various applications of big data, which has become vital in many areas of life.
