Comparison of Relational Database and Object Oriented Database

An object-relational database acts as an interface between relational and object-oriented databases because it contains aspects and characteristics from both models.

An object-oriented database is organized around objects rather than actions and data rather than logic. Therefore, an object database is a database management system in which information is represented in the form of objects as used in object-oriented programming.

Usually, when OODBMS is integrated with an object programming language, there is a much greater consistency between the database and the programming language because both use the same model of data representation. When compared to a relational database management system, an object-oriented database stores complex data and relationships between data directly, without mapping to relational rows and columns whereas a relational database stores information in tables with rows and columns.

Connections between two relations are represented by foreign key attributes in one relation that reference the primary key of another relation. It employs indexing techniques to locate disk pages that store the object.

Therefore, they are able to provide persistent storage for complex-structured objects.

Object–relational database

Object-oriented database design is not only a simple extension of relational database design. By modeling structure as well as behavior of real-world entities as coherent units, object-oriented database design succeeds in capturing more semantics of applications already in the design phase. The use of objectoriented concepts like inheritance promises a more adequate modeling and a better application implementation based on an object-oriented database system. However, the results of object-oriented design can also be applied to classical database systems. In this paper we briefly compare object-oriented database design with traditional design of relational databases. It is not our intention to end up with stating that one of the two approaches is superior to the other one. Instead we want to point out in which way particularly the object-oriented approach can still learn from the more established relational approach.


This report presents the comparison between object oriented database and relational database. It gives advantages of OODBMS over RDBMS. It gives.

An Object-Oriented database can utilize the benefits of both the design and implementation of any application. Due to the increased popularity of database systems many new database systems based on varying data model and implementation have entered in the market. Database systems have complex architecture but they are the key factors behind the business transformations.

It is a database management system based on the relational model i. It is a DBMS that enables the user to create, update, administer and interact with a relational database.
