Query Language

   In addition to a data dictionary, most DBMSs also provide a query language that enables a user to request and receive information directly from the database system. The complexity of this query language and the level of difficulty using it varies greatly with the DBMS. Some query languages are procedural and require step-by-step instructions to be written, as with a high-level language. Others accept English-like commands or guide the user with a series of fill-in questions, or even display menu on the terminal monitor form which the user must select a desired command.

   Query languages supplied with microcomputer database packages are almost always used to interact with the database and provide built-in help for novice users.
