Design

Concepts and principles

This software was conceptualized to fulfill the needs of the Service Industry by coupling a solid architectural backbone with detailed focus on Object Orientated Model/Design/Implementation using Microsoft.NET4.0/5 with its most recent and cutting edge class libraries.

 

The Object Orientated model and design concepts include OOA (Object Orientated Analysis), OOD (Object Orientated Design),  and OOP (Object Orientated Programming) as prerequisites, coupled with the SOLID principles which affords the OOD the ease of scalability, extensibility and maintainability and cutting edge nature of which Naomi boasts.

The framework technologies incorporated in the client/server software model are as follows; ASP.NET v4. 0, C#4. 0, Windows Communication Foundation (WCF v4. 0) and ADO.NET

 

A brief overview of the tiers and the supporting class libraries are provided to allow the reader to become familiar with these interacting software programming artifacts.

Architecture

The client/server application designed using the 3-Tier software architectural model as seen in the subsequent table.

 

Tier                            Class Library

------------        ------------

User Interface:      ASP.NET4.0

Business Layer:     C#4.0

Data Layer:          ADO.NET Entity Framework 5.0

 

This separation of software tiers provides the following advantages:

 

1. Scalability

2. Extensibilty

3. Security Management

4. Fault Tolerance

5. Maintainability

6. Performance

7. Portability

Framework

The .NET Framework was used to model, design and implement the behavior and functionality of the client/server application. 

It is an application development platform that provides services for building, deploying, and running desktop, web, and phone applications. Its main advantage in it's extensive class library, which includes tested, reusable code for all major areas of application development.

 

User Interface

ASP.NET server-side web application framework is used for its dynamic web forms/pages and event driven controls. The user interface dynamic content generation and interaction are driven by javascript due to its dynamic nature and affinity with AJAX (Asynchronous JavaScript and XML) and its underlying technologies such as Document Object Module (DOM) for dynamic content management, JavaScript Object Notation (JSON) for server to web application messaging and JQUERY for its extensive and efficient document management, manipulation and delivery capabilities.

JSON affords the advantage for the web application client to easily interact and fit mobile/tablet devices.
