A database is an organized collection of structured information or data, typically stored electronically in a computer system. Databases are designed to efficiently store, retrieve, and manage large amounts of information.

Key characteristics of databases include:

• Structured organization of data
• Support for data querying and manipulation
• Data integrity and consistency mechanisms
• Concurrent access by multiple users
• Security controls for data protection

Databases serve as the foundation for many applications and information systems we use daily, from social media platforms to banking systems and online shopping websites.
