SOFTWARE ARCHITECTURE
The architecture of the software is the interactions between the application layer and user interface, and between the data layer and the application layer. The detailed interactions will discuss in the next section.

LAYER MODELING.
This project implements the MVP design pattern.
Figure 2. MVP design pattern.
MVP is a user interface design pattern engineered to ease mechanical unit evaluate and improve the segregation of concerns in presentation logic.
The model is an interface demonstrating the data in order to displayed or acted upon in the user interface.
The view is an interface which shows data and paths user instructions (
http://en.wikipedia.org/wiki/Event_(computing)events) to the presenter to execute according to that data.
The presenter performs upon the view and the model. It receive data from sources (the model), and arrangements it for show in the view.
