Object Relational Database Management System (ORDBMS)



What is ORDBMS? / Define ORDBMS

ORDBMS

An object-relational database (ORD), or object-relational database management system (ORDBMS), is a database management system (DBMS) similar to a relational database, but with an object-oriented database model: objects, classes and inheritance are directly supported in database schemas and in the query language. [Source: Wikipedia]
Object Relational Database Management Systems (ORDBMSs) actually extend the RDBMS with the concepts like objects classes and inheritances etc.
This system simply puts an object oriented front end on a relational database (RDBMS). When applications interface to this type of database, it will normally interface as though the data is stored as objects. However the system will convert the object information into data tables with rows and colums and handle the data the same as a relational database. Likewise, when the data is retrieved, it must be reassembled from simple data into complex objects.
