Design and Implementation of Automated Airline reservation system

DESIGN AND IMPLEMENTATION OF Airline reservation system
( a case study of Aero Airlines Nig Ltd)

CHAPTER ONE/INTRODUCTION

1.1  Background of the Study

Throughout commercial airline history, the timely movement of aircraft, passengers and cargo has required the even more timely movement of information. This was never truer than today, where information has become not just an operational tool, but a competitive weapon. To capitalize on this information, the technological revolution and the information society have brought us a dazzling set of capabilities. But, they have also brought us a bewildering array of options for services, costs, methods and products. Many managers find themselves faced with too much of a good thing, too many alternatives. But, airline today means business. Commerce and tourism are the engines of economic development in today’s world. In Airline industry, Airlines, airports, and even governments are competing against each other for travel related income. Staying in front means making investments in enhanced customer service tools, improved management awareness, quicker access to operational information, etc.

All of the technology and service options, and the need to make rapid, well informed decisions, means that many organizations are finding it increasingly difficult, and expensive, to find and retain staff to meet the demands. The effective use of Airline Information System can help solve this problem.

Multi-database system for seat booking and ticketing is a very powerful integrated computer-based system for managing the technical operations activities of an airline, or aircraft fleet operator. The system can be used worldwide by large and small companies operating many types of fixed and rotary-wing aircraft.

The software designed will be used to collect, store, and analyze information about seat booking and ticketing within the industry.

1.2 Statement of the Problem

As aviation industry is expanding, a lot of airlines are coming up. The

passengers need to book for their flight tickets. The manual method of going

to their local offices to book for their flight ticket is becoming obsolete and

tasking. Flight schedule information needs to be publicized to passengers.

Hence the need for a wide range of publicity and enabling direct information

passage to the centers.

1.3 Aims and Objectives of the Study

In developing an airline seat booking system, we will always keep in

mind to provide to the users the best usability, flexibility and security.

Therefore, we need to make the user interface very flexible and

understandable.  Moreover, since the record updates is a database we need to

A REAL TIME TRANSPORT INFORMATION SYSTEM FOR PUBLIC BUS TRANSPORT SERVICE IN NIGERIA

ABSTRACT

Transport information systems are gaining increased popularity among public bus transport users in developed countries as it provides basic first hand and genuine real time travel information to road users. While these technologies are perceived beneficial to travellers in developed countries, these technologies have rarely been explored in developing countries. Also this research area are still very new and there are very limited studies on this topic. In developing counties such as Nigeria, travellers suffer daily from poor travel information such as unreliable route guidance information, unpredictable bus arrival times, unreliable traffic information, to name a few. The aim of this dissertation is to further explore the various information challenges Nigerian commuters face while using public bus transport as well as design a real time transport information system to improve the commuting experience of people who travel by public buses in Nigeria.

In order to fulfil the objectives of this study, this study adopted a combination of Mixed-methods Sequential Exploratory Design and Structured System Analysis and Design Methodology (SSADM) for the development of a real time transport information system. Structured online questionnaires and interview sections captured evaluation of real-life experience of road users with the developed system.

The results of this evaluation shows that the proposed system reveals genuine live travel information, such as bus arrival and departure times, schedule trips, estimate journey times, bus route information, vehicle information.

In conclusion, this dissertation has made a significant contribution to the field of information systems as it is a study that explored extensively the key information challenges road users encounter while travelling via public buses in Nigeria.

NETWORK SECURITY:ENSURING MAXIMUM PROTECTION THROUGH FIREWALL

NETWORK SECURITY:ENSURING MAXIMUM PROTECTION THROUGH FIREWALL

 ABSTRACT

The connection of an internal network to an external network such as Internet has made it vulnerable to attacks. One class of network attack is unauthorized penetration into network due to the openness of networks. It is possible for an attacker or hackers to sum access to an internal network, this pose great danger to the network and network resources. Our objective and major concern of network design was to build a secured network, based on software firewall that ensured the integrity and confidentiality of information on the network. We proposed an Object-Oriented Methodology and developed an improved software based solution that allows all the inbound and outbound traffic to pass through the firewall. The firewall in turn determines which traffic should be allowed in or out of the network. The firewall algorithm was implemented using Java programming language, which was based on java security architecture. It also utilizes the concept of XML and HTML programming which enables network communication over the Internet.

Chapter one/Introduction

Computer network is the engineering discipline concerned with communication between computer system and devices. The purposes of networking are exchange of data and resources sharing. With network, large volume of data can be exchanged through both short and long-range connections. Likewise computer resources such as hardware (printers, scanner etc.) and software can be remotely shared among network hosts.

With increase reliance on computer network, calls for serious monitoring of the traffic in and out of the system network. Attacker on the internet could break into the network and do harm in a number of ways; they can steal or damage important data, damage individuals computer or their entire network, and use the internal network computer resources. Due to some of these security threats, there was the need to build a defensive mechanism that ensures that attackers and their likes are not allowed into the network. Firewalls are designed to stop unwanted or suspected traffics from flowing into the internal network. Sets of rules are applied to control the type of networking traffic flowing in and out of the system. This would ensure that attackers have no access to the internal network.

This thesis is organized in four chapters. Chapter 2 provides theoretical background information about firewalls, roles, controls and their impact in network security; a comprehensive literature review on how network traffic can be monitored in order to prevent an unauthorized access to internal network. Chapter 3, we proposed and developed an improved software based solution that allows all the inbound and outbound traffic to pass through the firewall which, in turn determines which traffic should be allowed in or out of the network using object-oriented methodology. Chapter 4, Firewall security system was implementation using software-based solution. The use of Java programming language and the concept of xml and html programming were considered in order to achieve our objectives.

1.1 Statement of Problem

The problem to be solved is the problem of organizations network. What can firms do to protect their network over potential threats against the “resources” they share on the network?

1.2 Objectives

  1. To developed a firewall system to block unauthorized access to the network and prevent malicious attack which could lead to data loss
  2. To build a secured network, based on software firewall to protect network resources and ensured the integrity and confidentiality of information on the network are not compromised

1.3 Significance of the Study

The significance of this study is to show how a firewall could prevent attack and protect network resources which will make harder for an attacker to penetrate into the system. The system will be able to offer online services. The probability of exploring vulnerability will be reduced to low risk and the system will be more stable

DEVELOPMENT OF A WEB-BASED TAX ASSESSMENT SYSTEM

ABSTRACT

The aim of this project was to develop a web-based system that will contain all the information about the private sector assets for tax assessment. The objective was to register and assess all the assets of the entire private sectors establishment in a particular area for tax payment. These assets include: land, heavy equipment, light equipment, motor/vehicle, residential building, commercial building, and industrial building etc. The system will carry out tax assessment of the assets and enable the user to know the amount of money to pay on for the assets as tax. The system performs the following function: e-registration, tax evaluation, listing of designated banks, tax offices, and business firms. A questionnaire was used as an instrument for data collection on information about the existing system. A Structural System Analysis and Design Methodology (SSADM) were used in the design of the software. The system was implemented using WAMP SERVER, PHP, HTML, CSS and MYSQL technologies. The result of the study revealed that the web-based system enables a client to register his/her business, generate an acknowledgement slip, conduct a tax evaluation of his assets, generate a tax invoice, display a list of officially designated banks for tax payment, display a list of tax offices. and also display a list of existing business firms in the area covered by the web-based system.
