Introduction to NoSQL Databases
 
Introduction to NoSQL Databases is a practical, beginner-friendly course designed to help learners understand the core concepts, data models, and real-world applications of NoSQL technologies. As modern applications demand scalability, flexibility, and high performance, NoSQL databases have become essential for handling unstructured, semi-structured, and large-scale distributed data.
 
This course provides a clear, hands-on introduction to the major NoSQL categories—document, key-value, wide-column, and graph—along with guidance on when and how to use each type. Through interactive lessons and real examples, you’ll learn how to model data, query NoSQL systems, and apply NoSQL databases to modern application architectures and big data environments.
