Object-Oriented Programming vs. Procedural Programming

Procedural Approach
• Data Structures can be represented as a network of associated structures, referring to one another.
• Procedures can be represented as a network of routines which call one another, i.e., "call tree"

Object Oriented Approach
• Collection of discrete objects that incorporate data structures and behavior.
• Each data structure has, combined with it, the procedures which apply to that data structure.
• Contrasts with conventional programming in which data structures and behavior are only loosely connected
• These entities, called objects, can be associated to one another in one network, rather than two.
