Query

In computing, a query is a request for information from a database or a data source. It is the primary means by which users or applications interact with databases to retrieve specific data, manipulate existing data, or define new data structures. Queries are typically written in a specialized language, most commonly Structured Query Language (SQL) for relational databases, or various domain-specific languages for NoSQL databases. The precision of a query dictates the accuracy and relevance of the information returned.
