1. Introduction

1.1 Purpose

The main of purpose of this project is that to make online reliable vehicle rental web site to facilitate

people’s lives. Also, our goal is to create a fast-growing program that facilitates the work of

customers in changing internet environment standards. We will facilitate web site accessibility easier

by making online system. The agenda of the world, rapid change and development in technology has

put all organizations into a competitive environment. For this reason, the success and efficiency of

the private sector in order to raise up their presence is to a fairly high level. With the investigations we

made on the shortcomings of the programs on the market, our web site will be written in line with

customer demand due to the inability to demonstrate adequate development. One of our goals it to

create a harmonious alternative that every user group can easily use to respond to changing needs. We

want to be one of the best companies in the market by making large database and improving the web

site.

1.2 Scope of Project

This system is a software product, which is developing as web based. Software development system,

which will be held as a priority of the car rental. Our project has main parts. These are renting cars

We have a member login system on web site.

Customers will first register on the web site. With registration, all private information will be kept

with security measures. This system will also keep payment information. In this way, customer

information will not have to enter again. After registering with the information, the customer will be

able to login to the web site with his / her e-mail address and password. Once you have logged in, you

can view the rental vehicle or purchased vehicle information, personal information on the screen, and

update the information at any time.

The car rental section is divided into three options according to customer needs. The first of these

options is renting a car from the airport where the purpose is to provide transportation to our

customers from abroad. As long as the customer has internet access, he can rent the car he wants from

the desired city. Another option is to rent a car in the city where the customer is located, and the

customer can also rent a car for as many days as he wants.

Our final option is to rent a car from outside the city for our customers who want to go out of town. In

these options, price information will be displayed on the screen. Unlike other web site, the options we

aim to present are drivers, interpreters and guides.

The driver option is added for our customers who do not know how to drive, who are uncomfortable,

who are fond of luxury or who come from abroad and lose their validity here. The interpreter and

guide option is also a service we have chosen by considering our foreign customers. Our guides know

more than one language. Our customers will also be able to choose the gender of the guide, driver and

interpreter in line with their wishes.

We aim to address all domestic and foreign customers with our language option on our web-based

site. Another option offered by our web site is the currency. The customer can make an up-to-date

payment with the desired currency. Also, in any problem, our customer can contact us 24/7 via our

contact information. Our customers who have logged in for the first time can access all of our

information at about us option. They can reach the comments and satisfaction of the customers we

have worked with before.

These requirements are explained below three main titles. The first main title is, Functional

Requirements. These functional requirements are names as; Customer Use Case, Manager

Use Case, Employee Use Case. The last main title of the Specific Requirements is web site.

In addition, that report includes system design constraints and software system attributes. Our

2. Overall Description

2.1 Product Perspective

The car rental system is a program with database for the convenience of people. The car rental system

is a web site that will serve over the internet. It is aimed that the system to be developed can be easily

used. The user has a very useful interface in terms of environment. First of all, if the user is registered

in the system, the user can enter the name and password. Then the user's special page opens. It can

easily be reached by filtering in the system which wants to rent or buy. Member registration system,

language and currency options also provide convenience for the user.

2.2 Product Functions

Car rental system is a multi-user, easy-to-use database program. Featured features; the web

site is accessible via mobile devices with an internet. Customers are subscribing to the web

site. They log in to their account with a username and password. Account owners and

managers can only see user accounts.

2.3 User Characteristics

As the car rental system is a commercial program, everyone on the web site should be

suitable. Users who use this system need to know the project process. We can classify user

groups as managers and customers. The main target of the project is the customer. They will

use the program all day. The ease of use is the highest priority for this group. It should be

able to fulfill the content and design requirements of the web site. Customers will also have a

driver, interpreter and guide service. Other user group is managers. Managers should be able

to access all the features of the system.

The ease of use of the system management and settings section is important for this user

group. They will have access to all the data of the web site. Compatibility of the whole

system is important for this user group.

2.4 Constraints

The project has these constraints; hardware limitations (timing and memory requirements),

inter-application interfaces, tools and databases, language requirements, communication

protocols, security reasons, problems that can arise from the contract between the

administrator and the customer.

2.5 Assumptions and Dependencies

The car rental web site program has a high-capacity user system. There must be an internet

connection to access the web site. The user must be a member of the web site for car rental

operations. You must enter user information correctly to be able to log in. Once you have

created your account, you should contact the administrator.

2.6 Non-Functional Requirements

The screen resolutions of the system software will be the maximum resolutions supported by

the device to be operated. System interfaces will be designed accordingly.
