A better alternative is to allow structured data types, which allow a type address with sub parts street — address, city, state. The multimedia, medicine and high energy physics are some of the industries relying on object oriented databases.

OODBMS also includes support for classes of objects and the inheritance of class properties, and incorporates methods, subclasses and their objects. You featurew commenting using your Twitter account. Other message is used to update the value.

In object oriented database, information is represented in the form of objects. Every attribute of an entity must be expressed as a variable and a pair of message of the corresponding object in the object oriented model.
This means that the user cannot see the inside of the object but can use the object by calling the program part of the object.
