documentation on Online Air ticketing system

Introduction

This document contains discussion on various methodologies along with their strengths and weaknesses, which can be used to develop the proposed system (Online Air Ticketing System). It provides clarity and reasoning on why a specific methodology was chosen and others were not regarded. This document also contains a Software Requirement Specification with requirement prioritization, a project plan, and a development cost plan with design specification of the proposed system.  It will act as a framework for the development of the proposed system.

Scope

This document addresses the methodology chosen for the development of the proposed project along with development plan and cost estimation. It also specifies the requirements and prioritizes the essential functionalities of the system. Similarly, this document addresses the design specification of the project.

Assumption

Installation of system will increase speed and efficiency of the system users. The system's operational environment will have its own security requirements derived from business drivers or regulatory compliance mandates decreasing the attack surface of the system. The trust factor among the users and the new system will become more prominent. The system will have a simple user interface, will be user friendly and provide better backup facilities. The system will be robust which will allow the software to respond to unexpected conditions and will be interoperable allowing the proposed system to work with other systems. Data migration from the existing system to the new system will be performed by as set of customized program which will automatically transfer the data. The installation of the new system will be swift and all the components will work without errors.
