Question

In the context of OODBMS, define the following with appropriate examples.

I) Object Class

II) Abstract Class

Answer 1

An object is an instance of a given class. An object possesses a state and behavior. A class is defined and objects can be made which have different values but can share similar class definition. Objects correspond to variables and messages kept in them. 

Methods and variables template definition can be seen as abstract class. A class declared as an abstract cannot be instantiated directly, which shows that an object cannot be initialized from it
