A database is a structured collection of data that can be easily accessed, managed, and updated. It is a critical component of full-stack development as it stores the application’s data, such as user information, product details, and transaction records.

There are two main types of databases: relational (e.g., MySQL, PostgreSQL) and non-relational (e.g., MongoDB, Redis). Relational databases use tables to store data and SQL (Structured Query Language) for queries, while non-relational databases store data in formats like JSON or key-value pairs.

In full-stack development, the backend interacts with the database to perform CRUD operations. For example, a Django application might use PostgreSQL to store user data, while a React frontend retrieves and displays this data through a REST API. Databases ensure data persistence and integrity, making them essential for building robust web applications.
