what is a database

A database is a collection of structured data that is organized, stored, and managed in a way that allows for efficient retrieval, querying, and modification of information. It provides a way to store, organize, and retrieve information, and can be used for a wide range of applications, such as managing customer information, storing financial records, or tracking inventory. Databases are typically accessed and managed through a database management system (DBMS), which provides tools and interfaces for creating, modifying, and querying data.
