Definition

A database is an organized collection of structured information or data, typically stored electronically in a computer system and managed by a Database Management System (DBMS). Relational databases organize data into tables with rows and columns, and use SQL for querying. NoSQL databases offer flexible schemas for unstructured data. Databases power virtually all modern applications, from social media to banking.

Example

“An online retailer's database stores millions of customer records, orders, and product listings; when a customer searches for a product, the DBMS executes a query in milliseconds across these records to return relevant results.”
