3. Object-Oriented Modeling Implementation 

Certain situations of Object-Oriented Modeling (OOM) are implemented in analysis and design as top down approach 
that starts with Functional Decomposition of application system. 
This is build up on the concept that the system under analysis represents a single function, which can be broken down into successive level of details. 
The functions are identified as components of a process that combines to address a particular application system.

Data is described, using data flow diagrams, in terms of movement among these functions: for instance;
