What Is NoSQL?

NoSQL databases are non-relational databases that store and manage data differently from traditional SQL (relational) databases like MySQL or PostgreSQL. Unlike SQL databases, NoSQL databases don’t require a predefined schema, allowing for more flexible data storage, especially when dealing with unstructured or semi-structured data.

Why NoSQL Is Popular:

• Scalability: Ideal for handling large amounts of data across distributed servers.
• Flexibility: Schemas can change over time without impacting existing data.
• Speed: Many NoSQL databases provide fast data retrieval by prioritizing key-value or document-based storage models.

Now let’s dive deeper into the top choices.
