Database Systems Concepts, Architecture and NoSQL Databases

As the volume, variety, and velocity of data continue to grow, traditional relational databases often face challenges in handling largescale and unstructured data. To address these limitations, this book introduces NoSQL databases, which have emerged as powerful alternatives for modern data management needs. The text covers key NoSQL concepts, characteristics, and types, including documentoriented, key-value, column-family, and graph databases. Popular NoSQL technologies such as MongoDB, Cassandra, Redis, and CouchDB are also discussed to provide practical insights into their real-world applications.
