In cloud computing, a query is a request for data or information from a database. It's a way to retrieve information that matches specific criteria from a database.

• Queries are used to find specific data by filtering specific criteria.
• They can be used to manipulate and retrieve data in a database.

A query works by sending a request to a database to retrieve specific information.

• The database processes the query and returns a result set, which is the data that matches the query.
• Queries are usually written in a special language like SQL (Structured Query Language).

A cloud-based customer relationship management (CRM) system might use queries to retrieve information about a specific customer or group of customers. For example, a query might be used to find all customers in a specific city or all customers who have purchased a specific product.
