Database Queries

A database query is a request for specific information from a database. Think of a database like an organized digital filing cabinet, where data is stored in tables. When you want to find certain data—like all customers from a particular city or sales figures for a month—you send a query, which is a precise question or command. The database processes this request and returns the relevant data. Queries allow users and applications to efficiently retrieve, update, or manage data without manually searching through the entire database, making data access quick and effective.
