Determine the advantage of object-orientation

Finally, object-orientation has advantage of continuity throughout analysis, persistent representation and design implementation. 

• Object-oriented analysis, design and programming are related but different.
• OOA is concerned with creating an object model of application domain.
• OOD is concerned with developing an object-oriented system model to execute requirements.
• OOP is concerned in identifying an OOD using an OO programming language like Java or C++.
• Objects are abstractions of real-world/system entities.
• Objects administer themselves.
• Objects are independent and encapsulate the state and representation.
• System functionality is expressed in terms of the object services.
• Shared data areas are eliminated.
• Objects communicate by message transmitting.
• Objects can be distributed and can execute in parallel or sequentially.
