DBMS Types


Distributed DBMS

  • A Distributed Database Management System is a software system that permits the management of a distributed database and makes the distribution transparent to the users.
  • A distributed database is a collection of multiple, logically interrelated databases distributed over a computer network.
  • Sometimes "distributed database system" is used to refer jointly to the distributed database and the distributed DBMS.



  • Client server DBMS

  • The Client--Server DBMS Model has emerged as the main paradigm in database computing.
  • The Enhanced Client--Server architecture takes advantage of all the available client resources including their disk managers.
  • However, when updates occur at the server, some of the client data managers may need to not only be notified about them but also obtain portions of the updates as well.



  • ORDBMS

  • An object-relational database (ORD) or object-relational database management system (ORDBMS) is a relational database management system that allows developers to integrate the database with their own custom data types and methods.
  • The term object-relational database is sometimes used to describe external software products running over traditional DBMSs to provide similar features; these systems are more correctly referred to as object-relational mapping systems.



  • OODBMS

  • In an object oriented database, information is represented in the form of objects as used in Object-Oriented Programming. When database capabilities are combined with object programming language capabilities, the result is an object database management system (ODBMS).
  • An ODBMS makes database objects appear as programming language objects in one or more object programming languages.
  • An ODBMS extends the programming language with transparently persistent data, concurrency control, data recovery, associative queries, and other capabilities.
