Special Requirements: Technology and Data Variations List: None Frequency of Occurrence: Occasionally Open Issues: -What are the tax law variations? -What modifications are needed to be done for different companies?

Casual Format Use Cases Cancel Reservation: Main Success Scenario: Customer contacts to the office, requesting a cancel of reservation. Reservation info is checked in the system and the reservation is cancelled. Alternate Scenarios: If the reservation info is not found in the system, system returns a warning message, which indicates that no matching reservation registry is found in the system. In that case, customer is informed that he does not have an active reservation at the moment and no cancel operation is necessary. If the cancel operation is requested less than 24 hours before the delivery date, customer is informed and charged the late cancellation fine. Fine is charged from the credit card whose information taken from the customer during the reservation process. Manage Rent Period Main Success Scenario: Customer contacts to the office, requesting to extend or reduce reservation period. Reservation info is checked in the system and after checking that no period conflictions occur between other reservations, reservation period is updated. Alternate Scenarios: If the reservation info is not found in the system, system returns a warning message, which indicates that no matching reservation registry is found in the system. In that case, customer is informed that he does not have an active reservation at the moment and a new reservation is made according to the requirements of customer.

If the reserved car is not available in case of an extension request, customer is informed and another (probably a higher model) car is provided for that period. If the customer requests to reduce reservation period, customer will be charged with a slight percentage of daily rental price for the number of days reservation is reduced. Manage Car: Main Success Scenario: Manager calls the system to add a new car. Manager enters the information of the car and registers the car to the system. Manager searches for a car in the system. If the car state is free, car is removed from the system.

Brief Format Use Cases Reserve Fleet: A customer who would probably be a company contacts to an office requesting to reserve multiple number of cars. The staff member uses the car rental system to reserve multiple numbers of cars. The system checks the availability of such reservation on given period of time and required cars. If customer confirms reservation, staff member adds customer information to reservation and saves the reservation. Set Service Period: In cases like break down, accident or reaching casual service km; car will be sent to service. Approximate service period of the car will be added to car description by staff. Deliver Car: A customer whose rent period begins arrives at an office to take his car. Payment is handled at this point. Customer pays the rental price and system prints the receipt and adds the payment type to customer account. System changes the car status from reserved to on rent after printing the receipt. Car is delivered to the customer afterwards. Deliver Fleet: A customer (probably with multiple drivers) whose rent period begins arrives at an office to take his fleet. Payment is handled at this point. Customer pays the rental price and system prints the receipt and adds the payment type to customer account. System changes the fleet status from reserved to on rent after printing the receipt, and updates the state of each car in the fleet. Fleet is delivered to the customer afterwards. View Car State: A cars current status may be required for several reasons. A staff member directly searches the system from cars VIN number or selects the car from car catalog. The system presents the information of the selected car. Receive Fleet:

A customer arrives at a return point with the fleet he rented. A staff member checks each car one by one whether they satisfy returning conditions. The system makes the checkout of the customer and updates state of each car in the fleet. Manage Car: Manager logs into system to add or remove a car. To add a new car, manager goes to add car page and enters the properties of the new car to be added and confirms the operation. The system adds the car to the car catalog. To delete a car, manager selects the car from catalog or by search. Car can be deleted from the system only if it is in free state. Manage Office: Administrator logs into the system to add or remove an office. To add a new office, administrator goes to add office page and enters the properties of the office. To create an office, at least one manager and one staff member should be assigned to the office. Manage User: Administrator logs into the system to add or remove a user account. To add a new user, administrator goes to create account page, enters personal information of the user, determines whether the new user is a manager or staff member and assigns the new user to an office. To delete a user account, administrator selects the user from the user catalog or by search and deletes the account.

SUPPLEMANTARY SPECIFICATION DOCUMENT

Introduction: In our project we design and implement a car rental system, which will be used in car renting offices. The system keeps information about car and connects different offices through a network. Problem Statement: In the car renting company, processes like reservation and connection between two offices are managed by telephone calls between costumer-office and two different offices. This costs more in terms of time and money. In addition to that, hardcopy files were used to keep track of rented and available cars, which make workers’ life worse. Our system connects offices through network and controls the status of cars so it is much easier to control the information and status of cars. Summary of System Features:

• Rental Records •

Customer Management

• User Management (administrator, manager, staff) •

Payment Registry (cash, credit, check)

•

Reservation Records

•

Accounting Records (income, expenditure)

•

System administration for users: security, information tables High Level Goals and Problems of the Stakeholders.

High level goal

Priority

Problems and Concerns

Current Solutions

Fast and integrated renting process

High

Slow processing speed of the needs of the customer related

Building a car Rental software that can communicate with other shops

Getting access to car database easily and faster

Medium Difficulty in keeping track of the cars, reaching the record after some time, as they were foldered manually by Staff.

Building a car Rental software that keeps the record of the cars

User Level Goals The users (and external systems) need software to fulfill these goals. Staff: process reservations, handle return of the car, update car state, manage reservation and rental. Version

System Administrator: add or remove staff or manager accounts Manager: add a new car record or remove a car record.

VISION 1. Other Requirements and Constraints Introduction This document is the repository of all Car Rental Software requirements not captured in the use cases. 2. Usability Speed, ease and error-free processing are paramount in sales processing, as the customer wishes to leave quickly.

3. Reliability If there is a failure to use credit card transfer machine, try to solve it with a local solution in order to complete a receive process. 4. Performance As mentioned under human factors, customers want to complete the “taking the rented car” or reservation process. 5. Supportability 5.1 Adaptability Our software will work in every shop. Adapting the software to new computers is not a problem. 5.2. Configurability Configuration is not a problem, as software does not need any hardware configuration

6. Implementation Constraints Software will be programmed in Java and XML will not be used. Excel or text file can be used for database of the car records.

7. Interfaces Noteworthy Hardware and Interfaces: •

Receipt printer

Software Interfaces: We will have different systems for different processes like making reservation, canceling reservation, car search and etc. so we need to have different interfaces for these different processes. 8. Information in Domains of Interest 7. Documentation

Read me text file will be available with the program. Vision Report will also be ready for First Iteration of Elaboration further detail.

Requirements The requirements for the first iteration of the Car Rental System application follow: 

Implement a basic, key scenario of the Reserve Car use case: customer contacts an office and staff communicating with the customer reserves a car for the customer for a specific period of time.



Implement a Start Up use case as necessary to support initialization needs of the iteration.



Nothing fancy or complex is handled, just a simple happy path scenario and the design and implementation to support it.



There is no collaboration with external services, such as a tax calculator, fine calculator, credit card authorization, accounting system.



Customer determines where the car will be delivered and returned and the reservation period.



Customers are registered to system and are determined afterwards by their driver’s license number if they are new or already have an account.



Car description includes properties of car. Included information is: brand, model, year, color, state and most importantly VIN number for the car to be determined explicitly.



A car has four states: free, at service, reserved, on rent.



In iteration-1 there is only one office, one manager, one staff, one type of car, there are no previously registered customers.



Simulate car reservation requiring no actual car description, other than a specified car group and an imaginary car.



Pricing regulations are not applied.

The design and implementation of the supporting UI, database, and so forth, would also be done, but is not covered in any detail.
