NoSQL

NoSQL, which stands for "Not Only SQL", refers to a broad category of database management systems that are designed to handle a wide variety of data models, particularly non-relational or semi-structured data.
Unlike traditional relational databases, which use structured query language (SQL) to define and manipulate data, NoSQL databases offer a more flexible schema design and are optimized for large-scale data storage and retrieval.

Why NoSQL?

NoSQL databases are designed to handle:

• Unstructured or Semi-structured Data: data that does not fit neatly into tables, rows, and columns, such as JSON documents, key-value pairs, graphs, and wide-column stores;
• High Scalability: horizontal scaling, where databases can distribute data across many servers, making it easier to handle large volumes of data and high transaction loads;
• Flexibility: dynamic schemas that allow for the addition of new fields without the need for database downtime or complex schema migrations.
