Relational and Object Oriented Data Model

RELATIONAL MODEL

In this model, data is organized in two-dimensional. The basic structure of data in the relational model is tables. All the information related to a particular type is stored in rows of that table. 

OBJECT-ORIENTED DATA MODEL

In the object-oriented data model (OODM) both data and their relationship are contained in the single structure is known as an object.

The characteristics of the object-oriented data model are listed below:-

1. It keeps up a direct relation between real-world and database objects as if object do not lose their identity.

2.OODBs provide a system-generated object identifier for each object so that each object can easily be identified.

3.OODBs are extensible, which identifies new data types and the operations to be performed on them.
