query

(n.) A request for information from a database. There are three general methods for posing queries:

  • Choosing parameters from a menu: In this method, the database system presents a list of parameters from which you can choose. This is perhaps the easiest way to pose a query because the menus guide you, but it is also the least flexible.
  • Query by example (QBE): In this method, the system presents a blank record and lets you specify the fields and values that define the query.
  • Query language: Many database systems require you to make requests for information in the form of a stylized query that must be written in a special query language. This is the most complex method because it forces you to learn a specialized language, but it is also the most powerful.
  • (v.) To make a request for information from a database.
