##Online Car Rental System## Database Systems Project. Technologies: MySQL, PHP, HTML and CSS. Design and implement a database for keeping track of information about a car rental company. Following tasks were achieved: The following are the tasks for the third part of the project: Load some initial data (as discussed above) into the database.
You might have rented a car on your last vacation. You reserved your car online, and then picked it up from its designated location after paying all the previously-agreed charges. Once you were done, you returned it to the agency and perhaps paid some additional fees. Did you ever think about the system that makes all these things happen? In this article, we'll look at a data model for a car rental system.
- Car Rental Agreement Template This Car Rental Agreement Template is useful to any car rental, rent-a-car, or other vehicle rental service, and now you can save time and money getting contracts signed online. Car Lease Agreement Template Your customers can decide to lease a car from anywhere and you want them to sign it from anywhere.
- This is a car rental template that is available for download in a PDF format. This particular template can be easily customized for car owners who wish to rent their cars for a short duration of time. You can fill in the blanks in areas such as fee details, travel limitation, registration number, and other such rental.
Why Build Another Car Rental Data Model?
I want to design a data model of a fully functional system for an international car rental company. The company keeps vehicles to rent in various segments (mini, economy, intermediate, SUV, cargo and limousine). It operates its operations from various cities across multiple countries. The company allows their customers to rent a car from one location (pick-up location) and drop it off in another location (drop-off location).
At this point, let's refer to an earlier article that explains a simple car rental company model. This model caters to all the fundamental services offered by a car rental company.
Before we add new functions, I would like to incorporate some minor changes into this model, namely:
- Adding
city
as a column in thelocation
table, and removing the city table altogether. Adding one additional column,
zip
(as in ZIP code, or postal code), in thelocation
table. This system will identify a pickup/drop-off location by its ZIP code. There are many countries where ZIP code is an alphanumeric number, so I will keep this column as a varchar column.Adding
driving license issue date
to thecustomer
table. There are some countries where the maximum speed limit depends on when the license was issued to the driver.
category
table to car_category
, which describes its content more precisely.flight_detail
and connect it to the reservation
table.Adding Customer Invoice Information
For invoicing, we need to store a rental value for each inventory item, including cars and equipment. The rental cost is assigned to each category, because the reservation process deals with categories rather than individual cars.
Let me add rental_value
in the car_category
and equipment_category
tables.
On similar lines, there must be some cost associated with insurance. This cost is determined by the insurance company. For now, I'll add one more column, cost, in the insurance
table.
For invoicing, I create a separate table to store all invoice details. This way, these same details can easily be retrieved whenever needed. Since the computation of these values is a bit tricky, I won't repeat them again and again for an invoice. I'll add one table, namely rental_invoice
, that is primarily connected with the rental
table.
The rental_invoice
table contains the following columns:
id
– the primary key of this table.rental_id
– the primary key of therental
table. I will add one unique constraint on this column: there can be only one record for each rental.car_rent
– This column signifies the rental costs for the rented vehicle.This cost can be determined using the following SQL:
equipment_rent_total
– This column shows the amount to charge for any equipment rented out to the customerThe total cost can be determined using the following SQL:
insurance_cost_total
– This column is for the customer's total insurance cost. This can be determined by using the following SQLservice_tax
andVAT
– As their names suggest, these columns store values for applicable service tax and VAT.total_amount_payable
– This column will contain the value of the total invoice amount. This would be the sum of following columns:total_amount_payable = car_rent + equipment_rent_total + insurance_cost_total
waiver_amount
andnet_amount_payable
– These columns store values for waiver amounts (if any) and the net amount due for payment. Thewaiver_amount
is how much will be waived off the total invoice. It is commonly used when a rental company offers a discount to customers. The formula for determiningnet_amount_payable
looks like this:net_amount_payable = total_amount_payable – waiver_amount
Mobile Inventory – For a car rental company, its inventory is always mobile because it is moving from one location to another. If you've noticed a checkbox saying ‘returning to different location?' when you reserve a car online, you've seen it in action. The system treats your request a bit differently if the returning location is NOT the same as pickup location. The system always keeps a track of its inventory as and when it is rented out and returned.
For example, one customer rents a car from Chicago, confirms that the drop off location will be different, and drives to his destination in Saint Louis. Obviously, he'll drop off the car at the company's Saint Louis location. In this case, as soon as he drives the car from the Chicago location, this part of the inventory is no longer tied up to that office. The car will get registered again, this time with the Saint Louis office, as soon as he is done with it.
To incorporate this mechanism, I will add one column, namely current_location_id
, in the car
table as well as the equipment
table. This column holds only the valid IDs of locations from the location
table.
So, with the above example, the initial location of the car is Chicago; it will be updated after the customer returns the car to the destination office.
Setting Up Fueling Options
Most car rental companies give the following types of fueling options:- Fuel Service Advance – the customer pays for a full tank of fuel in advance, and returns the car with an empty tank.
- Fuel Service Charge – the customer gets the car with a full tank of fuel, but pays for it based on fuel usage.
- Fuel Self Service – the customer receives the car with a full tank of fuel and returns the car with a full tank. This is the most widely-accepted option of the three.
Here, we are not concerned about which option the customer chooses. What we want is to register their choice while processing the rental request.
To meet this need, I'll add one table, fuel_option
, that stores all possible options for fueling the car. There must be one-to-one mapping between a rental request and the fuel_option
, since the customer is asked to select one at the time of booking the rental.
The Final Car Rental Data Model
In many areas, car rental companies are shifting toward using a keyless, self-service renting experience for their customers. They do not want to make their customers wait at a counter just to complete paperwork and pick up car keys. Can our current data model cater to such requirements? What changes are needed in our data model to make it happen?
