Introduction

Databases are an essential component of modern computing technologies as a structured way to store, retrieve, and manage data efficiently. SQL is the standard language for interacting with relational databases.

Databases can be classified into two types based on their use of SQL:

• SQL Databases: These are traditional databases that use Structured Query Language (SQL) for managing and manipulating data. They are known for their strong consistency, ACID compliance, and support for complex queries. Example: MySQL, PostgreSQL, etc
• NoSQL Databases: These are non-relational databases that do not use SQL. They offer more flexibility in data models and can handle large volumes of unstructured or semi-structured data. Example: MongoDB, etc
