A NoSQL database, short for "Not Only SQL," is a non-relational database that provides a mechanism for storage and retrieval of data that is modeled in means other than tabular relations used in relational databases. These databases are designed to handle large volumes of unstructured, semi-structured, or structured data and are well-suited for big data applications due to their ability to scale horizontally, provide high availability, and support flexible data models.

NoSQL databases are classified into four major types: Column-oriented, Document-oriented, Key-Value Stores, and Graph databases. Each of these types is optimized for specific data storage and retrieval needs, making them useful in different data science and big data contexts.
