Many of these concepts apply to all forms of database management systems: relational (RDBMS), object (ODBMS), XML (XDBMS), and others as well as object-relational mapping and XML-mapping products. This is one of several possible architectures; each system has its own variations. These extensions implement database objects such as new data types, application-level object classes, analytic algorithms, and external data-access facilities. • A Database Management System, or DBMS, is a computer application that allows you to work with databases on a computer. - More than 450,000 Searches per day.
