What are the advantages of object oriented methodology?

Object Oriented Development (OOD) has been touted as the next great advance in software engineering. It promises to reduce development time, reduce the time and resources required to maintain existing applications, increase code reuse, and provide a competitive advantage to organizations that use it.

What are the advantages of object oriented design?

Some of the advantages of object-oriented programming include: 1. Improved software-development productivity: Object-oriented programming is modular, as it provides separation of duties in object-based program development. It is also extensible, as objects can be extended to include new attributes and behaviors.

What is difference between OOA and OOD?

Models are also used to describe the relations between objects created as instances of the various classes. … In general, the primary difference between the OOA models and the OOD models is the higher level of abstraction for OOA objects and their relations.
