In databases, data retrieval is the process of identifying and extracting data from a database, based on a query provided by the user or application.
It enables the fetching of data from a database in order to display it on a monitor and/or use within an application.
Data retrieval typically requires writing and executing data retrieval or extraction commands or queries on a database. Based on the query provided, the database looks for and retrieves the data requested. Applications and software generally use various queries to retrieve data in different formats. In addition to simple or smaller data, data retrieval can also include retrieving large amounts of data, usually in the form of reports.
