4. RENT A CAR MANAGEMENT SYSTEM
1) Introduction
Rent a car management system provides us with best possible services and the fastest service
amongst all. They provide variety of cars to us which include all luxury cars, coasters, hi-roof and
buses. They also provide pick and drop service at your doorstep. You can call and place your
order or you can even place your order online. Best possible car service in the cities. The data is
not at all organized and the registers and journals are stored in cupboards that are jam packed
and have no more space. The data stored is now in a bad condition due to harsh use. The pages
are coming out thus data can easily be lost. Updating current information is also very difficult
and sometimes new registers must be made. This increases the amount of registers which in
turn make it even more difficult to store and even to search for data manually.
Purpose
The company wants to reduce the time it takes for them to perform their daily operations. The
system is being developed to meet the modern standards of information technology. The new
system helps to manage all the existing operations very easily and efficiently. Renting out,
maintaining records and data on vehicle fleet, operating the customer and reporting is major
operations of the system. The system does not fulfill any other need of the business other than
maintaining data and records of their employees and customers.
Document convention
The Times font is being used for writing this SRS. Font size is 18ppt for main heading 14ppt for
subheading and 12ppt for normal writing. Every requirement statement has its own priority.
Intended audience and reading suggestion
Document is intended for project managers, developers and users. Document contains the
product scope. What system intends to do and what not to do (borders). It contains overall
description of the system what classes being used in the system, what is operating environment
of the system. User characteristics external interface requirement and system features. The
most pertinent sections are product scope, system function and external dependencies.

5. Product scope
The system that is going to be developed is known as the CRMS. The users of this system are
client (Renter), employee (Dealer), supervisors, managers, VP’s and CEO (owner). Scope of the
project is:
 The system should be efficient and fast
 There should be validation checks to prevent any incorrect entry of data.
 The data in all the tables and forms should have a professional look.
 The adding, editing and deleting of records must be possible.
 Data must be available in a hardcopy in form of reports.
 Moving between forms must be easy and fast.
 A huge storage space must be available for the increasing entries.
 Entering of data in the forms must be easy
 Searching for data from the forms must be easy.
 Editing of the data in the forms must be easy.
 The forms and tables should be user friendly.
2) overall descriptions
Product perspective
The system must be designed with 10 main modules in the mind. Most important module is to
keep the track of customer data and cars fleet data. Organizing the data in such a way so it can
be used to make the daily operations more efficient and less time consuming. Also, the system
should respond fast as main purpose for adopting this business model is to achieve fast access
to data and maintain all the record. Other important modules are that user interface should be
friendly and easily understandable so that no training of the employees is required. Record can
be edited and easily be maintained. System should have a large storage as with passing timing
number of data entry records keep on increasing.
Product functions
Product functions include:
o Saving, updating, deleting Customer details
o Saving, updating, deleting Employee details
o Saving, updating, deleting Car details
o Saving, updating, deleting Stock details
o Renting out a car and maintaining Stocks
o Updating stock when a car is returned back

6. User classes and characteristics
The user for the system will be the employee who is renting the car to the customer. The
customer can be on a business meeting, out of the town visitor or can be a local resident in need
of a car. Other user of the system will be the managers using the system for keeping an eye on
the employees and tracking the cars by keeping the records organized. The system can be used
both at sub offices and main headquarter.
Operating environment
 The compatible operating system for the system will be the windows XP, 7, 8, 8.1 and 10 as
all these are used by vast majority of the peoples. Deployment of this system will be on
windows 7 but it can be used on above stated version of windows as well.
 The hardware module will be amd64 and amd32 architecture both will be compatible with
this system.
 No other dependencies for this system. The installation file will include all necessary software
components.
Design and implementation constraint
The system design implementation will be in the java language. The other constraint will be the
use of database. The database will be created in the MySQL Workbench. The other constraint
will be the operation system and the system running platform should be same.
User documentation
Each and everything should be documented for the future ease and for users ease also. User
manual will be given with the deployment of the training session. Training session will be held
at the start of the system deployment. Tutorials will also be given for later use of training new
staff if needed.
Assumption and dependencies
 The major dependencies about this system is the availability of customers with respect to
availability of vehicles.
 Also, customers renting out the vehicles should return it on the following day. So that
schedule of cars should not change.
 The broken cars should also be dependency as this also supposed to change vehicles
availability.
 If a customer returns a car with a major accident or faulty car that case used also be
considered.

7. 3) External interface requirement
User Interfaces
The user interface will be the GUI for the system. The GUI can be easy understandable and will
be user friendly. The users are employees of the company the system will be help full for
generating automatic weekly and monthly reports, thus, keeping track and managing renting out
will be a lot easier for the employee. The new approach is being used to make this GUI so that
more and more stuff can be handle and seen on the screen. The optimal screen monitor size for
this GUI will be 20 inches. Lesser size can create merging of some text or lesser screen view. The
help button will only be seen on the main menu form. The slandered buttons are being used.
Keyboard shortcuts are same as window operating system. Newer are CTRL+M to go to menu
from any form. Also, to see available car information and list simply press CTRL+L.
Hardware Interfaces
The following hardware interface will be used: -
 The system will have 2 terminals per outlet, with each outlet will have touch screen monitor,
keyboard, credit card scanner and cash register.
 1-hour backup will be at each outlet for the system.
 The system will have 5 hours backup for main servers at the headquarters.
Software Interfaces
The main software interfaces will be
 The system need to communicate with the servers at the headquarters, so this connection
must be implemented.
 For payment and transactions, the system must interact with any banking network.
Communication Interface
 For communication the specific email is being used in the system itself. It’s basically take you
to a browser (Browser dependent on the OS) and then prompt you to login.
 The communication between the server and the terminal at any outlet is being secured by
FTP.
 Instead of telnet the SSH is being used.
 VPN being used all the type.
 All sensitive emails can be encrypted by the system built in encryption tool.

8. 4) System features
The system major feature is to add entries and keep track of all the entries and rented out cars.
It also maintains the stock you can check ow many cars are in stock and how many have been
rented out.
Functional Requirements

5) Other Nonfunctional Requirements
Performance Requirements
The system must be efficient. It should be capable of running all the timesmooth. Also if an error
occurs the system must not shut down and keep working for basic operations. The main server
computer should be run fast and should be up for all the time. The system response should no
longer than 1.0 seconds in order to keep up with customer actions. As more and more data enter
with company being more famous the system must be able to scale up the speed, size and
versatility in order to accommodate the rising needs of the customers. The system should have
carried out 1000 tasks per minute.

10. Security Requirements
The system deals with customer’s private information, credit card details and other payment so
the security is a main concern for any customer. System should make sure that customer data
should be safe and secured and private information should be encrypted so that no employee
can access that. Also, system should be safe from any attack on the system itself. There should
be a backdoor if any person attack on the system itself it should go in there and shutdown and
encrypt all its information so that no one can access the customer data. Security is one of the
highest priority.
Safety Requirements
The system safety is concerned with the working of the system if any error occurred due to any
reason. As company cannot afford any kind of system shut down during customer opening time
so it must be assured that system should be in working condition despite of any error.
Software Quality Attributes
The system should be easily upgradeable without any major change in its current working. Also,
the system should be dynamic to the need of the employees. The implementation of system
should not be static as dynamic is more and more in coming days. The main system attributes
will be work flow, efficiency and security. Also, the ease of adding a new functionality.
Design Constraints
The system will be constrained by the operating software of the host system and will need to be
able to function with different servers.
1. The system will be constrained operating system of the host computer which uses windows
operating system.
Business Rules
Business projection is the one of the major non-functional requirement which can affect the
system. If the owner of system changes or multiple owners having clash between them then it
can seriously affect the system development. So, business rule must be considering at every
stage of development. The contract with the system owner should be renew after each major
development or it should be in the start of the system for the whole system.

11. Usability Requirements
Customer usability
For end customers the system is easy to understand. The time should not be more than 5
minutes for the customers for familiar with system.
Admin usability
For administrator giving maximum 3 days training for system understanding and all functionality
of system should be clear.
Availability
The system should always be available for access at 24 hours, 7 days a week. Also, in the
existence of any major system malfunctioning, the system should be available in 1 to 2 working
days, so that business process is not severely affected.
Error handling
Error should be considerably minimized and an appropriate error message that guides the user
to recover from an error should be provide. Validation of users input is highly essential. Also, the
standard time taken to recover from an error be 15 to 20 second.
Ease of use
The user of this system possessed the considered level of knowledge, a quality and simple user
interface should be developed for making the system easy to use, understand and require less
training time.

30. ARCHITECHER DESIGN
1) Model view controller
The Model-View-Controller (MVC) is an architectural pattern that separates an application into three main
logical components:the model, the view, and the controller. Each of these components are built to handle
specific development aspects of an application. We can use model view controller design pattern for rent
car management system.
Model
Managingthe dataof the application.Itrespondstothe requestfromtheviewanditalsorespondstoinstructions
fromthe controllertoupdate itself Responsible for maintainingdata.
View
The viewdisplaysthe data(the database records).A view requestsinformationfromthe model,thatit needsto
generate anoutputrepresentation.
Controller
The controlleristhe part of the applicationthathandlesuserinteraction of model andview.Typically,controller
read data from a view, control user input, and send input data to the model. It will handle input, typicallyuser
actionsand mayinvoke changesonthe model andview.
2) Layered architecture
This pattern can be used in our rent car management system. The most commonly found 4 layers of a general
informationsystemare asfollows.
Supports the incremental development of sub-systemsin different layers. When a layer interface changes, only
the adjacentlayerisaffected.
Presentationlayer(alsoknownas UIlayer)
Applicationlayer(alsoknownas service layer)
