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.
