Hi Deepak Kumar Shyoran, your answer s very useful. I've one more doubt about the standard objects, Is there poissible to create Master-Details relations between two standard objects.
No, You can't create Master Detail Relationship between standard object as when a master is deleted then child record deleted automatically. Due to this property, salesforce does not allow master detail relationship between two standard object.

This is standard relation ship established between all standard objects by Salesforce it self.
We have Lookup of Contact in Account and Lookup of Account in Opportunity as well.
from development point of view:
Contact and Account ( one to many )
Account to Opportunity ( one to many)
from business point of view:
Generally we consider
Contact as Person
Account as Client /vendor
Opportunity as business options/projects
One Person has many clients and one client may brings many opportunities to person/company.
