Difference Between Object Oriented Database and Object Relational Database

The main difference between Object Oriented Database and Object Relational Database is that Object Oriented Database is a database that represents data in the form of objects like in Object Oriented Programming while Object Relational Database is a database that is based on the relational model and object-oriented database model.

A database allows storing and managing data easily. A relational database, on the other hand, is based on the relational model proposed by E.F. Codd. Object-oriented database depends on object-oriented Programming concepts while object-relational database is based on features of relational databases and object-oriented databases. In brief, an object-relational database is an advanced and enhanced version of object-oriented database. In other words, an object-relational database is a hybrid of the relational model and the object-oriented model.

What is Object Oriented Database

Object-oriented databases represent data in the form of objects and classes. According to the object-oriented paradigm, an object is a real-world entity. In addition, a class helps to create objects. Moreover, object-oriented databases follow the principles of object-oriented programming.

In addition, object-oriented databases support OOP concepts such as inheritance, encapsulation, etc. It also supports complex objects such as maps, sets, lists, tuples or collections of multiple primitive objects. Furthermore, Object-oriented database allows the user to create persistent objects which help to overcome the database issues such as concurrency and recovery. These objects stay in computer memory even after completing the execution.

What is Object Relational Database

Object-relational database is an improved version of the object-oriented database. It provides a solution to the issues users face in object-oriented databases; some of these issues include cost for computing resources, possibilities of design errors and data inconsistency. However, it is also important to note that object-relational database is based on both the relational model and the object-oriented database model.

Furthermore, these databases support objects and inheritance and provide a better interface for many object-oriented languages. Users can also use data model extensions with custom data types and methods. Moreover, companies such as Microsoft, Oracle, and Sybase have object-relational versions of their products. These databases are more applicable for applications that consist of a large number of short-lived transactions on data items with complicated structures.

Difference Between Object Oriented Database and Object Relational Database

Definition

An object-oriented database is a database that represents information in the form of objects as used in object-oriented Programming. An object-relational database, on the other hand, is a database that depends on the relational model and the object-oriented database model. Thus, this is the main difference between object oriented database and object relational database.

Based on

Moreover, object-oriented database depends on OOP while object-relational database depends on the relational model and object-oriented database model.

Improvement

Another difference between object oriented database and object relational database is that object-relational database is more improved than object-oriented database.

Conclusion

In conclusion, object-oriented database and object-relational database are two useful databases. The main difference between object oriented database and object relational database is that object oriented database is a database that represents data in the form of objects like in object-oriented programming while object-relational database is a database that is based on the relational model and object-oriented database model. In brief, object-relational database is an improved version of object-oriented database.
