Answer Posted / debangshu chatterjee
in object oriented design decomposition of the system is in the object point of view while in FD decomposition of system is in functional point of view.OOD design identifies object and decompose complex objects into simpler objects while in FD same is done on function.more over unlike FD data is not centralized in OOD.object oriented design is good when there are fixed number of OPERATION on THINGS.while FD is good when there are fixed number of THINGS on which OPERATIONS are performed.thus in OOD implemetation is done by adding new classes which implement existing methods, and the existing classes are left alone, while in FD new functions are added on existing things.
