Question

In the webEx portal, the customers have registered their information. Which Object oriented principle ensures that the customer object is persisted even after the creator of the object ceases to exist

Answer 1

Answer:

Persistence is the answer.  

Explanation:  

The object model is the main concept in Object-oriented systems. There are 2 categories of 'elements' - they are Major and Minor.

• The 'major' elements are 'Abstraction', 'Encapsulation', 'Modularity', and 'Hierarchy'.
• The 'minor' elements are 'typing', 'concurrency' and 'persistence'.

Persistence: The memory space is occupied by an object and it holds its existence for a 'particular period of time.'  

In databases or files, the 'lifespan of the object' is 'greater' than the time taken for the process to create an object. This property by which an "object continues to 'exist' even after its creator 'ceases to exist' is known as persistence."
