The basic abstractions, which are given to the user, are real world functions.
The basic abstractions are not the real world functions but are the data abstraction where the real world entities are represented.

It views system as Black Box that performs high level function and later decompose it detailed function so to be mapped to modules.
Object-oriented design is the discipline of defining the objects and their interactions to solve a problem that was identified and documented during object-oriented analysis.
