Abstract

The purpose of this document is the design of a Rapid Realization of a Communication Service System upon which all decisions regarding the Rapid Realization of a Communication Service System shall be made. This document will show the specific methodologies and patterns used in the systematic design of such a Rapid Realization of a Communication Service System. Furthermore, this document displays the results obtained by providing a very representative view of the system from a design stand point. This document will answer, through the decomposition of the purpose, proposed architecture, and object design, all relevant questions regarding the design of a Rapid Realization of a Communication Service System.

1. Introduction

This chapter constitutes and introduction to the Rapid Realization of Communication Services System. This chapter will cover the purpose of the system, functional and nonfunctional requirements, design methodology, definitions, acronyms, abbreviations, and overview of this document.

1.1 Purpose of the System

The purpose of the system is twofold. First, the system will use a model-driven approach to create an application that can handle voice and video communication and chat. All aspects of the programming and engineering of the application will be hidden to the end user; and all the implementation details will be considered only once, when the Rapid Realization of Communication Services has been created.

Second, the benefits of the system will be apparent once the system itself has been created a
