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.
