Object-relational database (ordbms) is also a dbms that extends rdbms to support a broader class of applications and attempts to create a bridge between relational and object-oriented paradigms as mentioned, earlier rdbms is based on the relational model and data in a rdms are stored in the form of related tables.

For an object-oriented application involving complex data relationships to work with a relational or object relational database, code must be written to map the complex object structure into the simple storage model of the relational database. Rdbms vs oodbms an object-oriented database management system (oodbms), sometimes referred as object database management system (odms) is a database management system (dbms) that supports modeling and creation of data as objects.
