Database

Definition

A database is an organized collection of structured information, or data, typically stored electronically in a computer system. A database is usually controlled by a database management system (DBMS).

Why It Matters

Databases are essential for storing, managing, and retrieving data for almost any application, from simple mobile apps to large-scale enterprise systems. They provide a reliable and efficient way to handle persistent data.

Contextual Example

A social media application uses a database to store user profiles, posts, comments, and likes. When you view a profile, the application queries the database to retrieve that user's information.

Common Misunderstandings

• A database is not just a collection of files like spreadsheets. It is a structured system managed by a specific software (DBMS) that provides features like querying, security, and data integrity.
• There are many different types of databases, primarily divided into relational (SQL) and non-relational (NoSQL).
