Database Management System - Modeling Language

Modeling Language

A modeling language is a data modeling language to define the schema of each database hosted in the DBMS, according to the DBMS database model. Database management systems (DBMS) are designed to use one of five database structures to provide simplistic access to information stored in databases. The five database structures are:

  • the hierarchical model,
  • the network model,
  • the relational model,
  • the multidimensional model
  • the object relational model,
  • the object oriented model,and
  • the object model.

Inverted lists and other methods are also used. A given database management system may provide one or more of the five models. The optimal structure depends on the natural organization of the application's data, and on the application's requirements, which include transaction rate (speed), reliability, maintainability, scalability, and cost.

Famous quotes containing the words modeling and/or language:

    The computer takes up where psychoanalysis left off. It takes the ideas of a decentered self and makes it more concrete by modeling mind as a multiprocessing machine.
    Sherry Turkle (b. 1948)

    In a language known to us, we have substituted the opacity of the sounds with the transparence of the ideas. But a language we do not know is a closed place in which the one we love can deceive us, making us, locked outside and convulsed in our impotence, incapable of seeing or preventing anything.
    Marcel Proust (1871–1922)
