Disadvantages of object oriented approach

Answer 1

These are some of the major advantages of OOP. Simplicity: software objects model real world objects, so the complexity is reduced and the program structure is very clear. Modularity: each object forms a separate entity whose internal workings are decoupled from other parts of the system. Modifiability: it is easy to make minor changes in the data representation or the procedures in an OO program. Changes inside a class do not affect any other part of a program, since the only public interface that the external world has to a class is through the use of methods. Extensibility: adding new features or responding to changing operating environments can be solved by introducing a few new objects and modifying some existing ones. Maintainability: objects can be maintained separately, making locating and fixing problems easier. Re-usability:objects can be reused in different programs.

Answer 2

The disadvantage and advantage is of oriented approach are many. To start the advantage is reduce maintenance and real-world modeling. It is also improved reliability and high code reusability. The disadvantages are it is not a panicky it is not technology and it has not been accepted by major vendors yet. also it is often difficult finding certified programmers and DBA.
