Database

A structured collection of data, typically stored electronically in a computer system and designed for efficient retrieval, management, and modification of information. It organizes data to facilitate various operations, including querying, reporting, and analysis. Databases ensure data consistency, integrity, and security, making them fundamental for numerous applications, from simple address books to complex enterprise resource planning systems. They are built upon various models, such as relational, NoSQL, and object-oriented, each with its own architecture and operational principles. Careful design and implementation of a database are essential for performance and reliability.
