This document describes a student project on a vehicle parking system. It includes an introduction, scope, objectives, data flow diagrams, entity relationship diagrams, relational database model, queries, and interfaces. The project aims to create an automated system to manage vehicle entry and exit from a parking area. Information like vehicle type, registration number, entry time, exit time and generated bill amount will be stored. Queries are written to retrieve and analyze data from the database tables created to represent different entities. Screenshots of the user interface designed in Visual Studio are also included.

3. ACKNOWLEDGEMENT
In the beginning, I would like to thank ALMIGHTY ALLAH, the most merciful and
beneficent, for giving me the strength to complete my project with full
determination.
I would like to thank my teacher Sir Usman Sattar who gave me this opportunity and
encouraged me by assigning this project; Without their help and guidance I would
have not completed this assignment. I believe in future these efforts will pay off.

4. INTRODUCTION
This project is about “Vehicle Parking system” of any plaza or
mall, its a automatic recepit generated software with every essential details.
SCOPE
As we all know that the world is advancing day by day new technologies
come and go, many new methods are been introduced almost daily, therefore, the
demand of the new systems have been increased in every organization old systems
have been replaced by new systems, the question is why? Its because every
organization demands excellent quality work more profit to be earned in short span
of time, to gain as much market trust as they can, and not to forget as quick they
can so they can compete with other organizations. New systems should be
i. User friendly
ii. More efficient
iii. They should provide security
iv. Fast
As these four are mentioned, my idea will be based upon these.
OBJECTIVE + PROBLEM
As the world is facing many thread’s daily, robbries are done easily
with no track to trace, bomb blasts occur with the use of car, so if a proper system is
adopted each and every record can be saved and anyone can be track easily
therefore mainly is to make a better and fast software, most important user-friendly.

5. Vehicle Parking System
Flow:-
A vehicle is entering the typist type vehicle_type, registration_no,
date, time_in (time of vehicle entered). And an auto generated slip_no is given to
the specific car; now vehicle is exiting after some sum of amount for which we have
different rates, the customer returns us the slip from there we only type the slip_no
on the system and all the previous information will pop up with some more which
are following time_out (time of vehicle exiting), total_time (calculated from time_in
and time_out), total_amount (which is based upon total_time), this is the whole
process which is converted into computer language.
Data Flow Diagram (DFD):-
Following is the DFD of the system.
Vehicle_type Rates
Vehicle_info
Parking System
Processing
Vehicle Type
1- Car
2- Bike
Hourly rates
Finallyafterthe processing
the record issavedin
Vehicle_info

6. Entity Relationship Diagram (E-RD):-
Following is the E-RD diagram of the system
One vehicle will is either a car or bike, and its calculated amount can be only one amount
therefore, Its 1 to 1 relationship between tables.
Vehicle_type
T_id
V_type
Rates
R_id
R_per_hour
R_s
Vehicle_info
Slip_no
V_type
Registration_no
Date
Time_in
Time_out
Amount

7. Relational Datamodel:-
Look-up Tables:-
 Vehicle_type
 Rates
R_id R_per_hour R_s
1 0.00 - 1.10 10
2 0.00 - 2.00 20
3 0.00 - 3.00 30
4 0.00 - 4.00 40
5 0.00 - 5.00 50
Main Table:-
 Vehicle_info
Slip_no T_id Registration_no Date Time_in Time_out
1 1 LEX – 1313 From sys From sys From sys
2 1 LZY – 1790 From sys From sys From sys
I prefer the Denormalization concept for my project as i don’t think an normalization
is needed for such a project.
T_id V_type
1 Car
2 Bike
* and so on records will be saved a IF statement
will be required to calculate total amount from
time_in & time_out

8. Queries:-
Following are the queries from which these tables are created and random data is
inserted into it.
 Query to create Database
CREATE DATABASE vehicle_parking_project
 Query to create table (vehicle_type)
CREATE TABLE vehicle_type
(
t_id INT IDENTITY NOT NULL PRIMARY KEY,
v_type char(5)
)
 Query to insert data into table (vehicle_type)
INSERT INTO vehicle_type
VALUES ('Car')
INSERT INTO vehicle_type
VALUES ('Bike')
 Query to create table (rates)
CREATE TABLE rates
(
r_id INT IDENTITY NOT NULL PRIMARY KEY,
r_per_hour char(10),
r_s INT
)

9.  Query to insert data into table (rates)
INSERT INTO rates
VALUES ('0.00-1.10',10)
INSERT INTO rates
VALUES ('0.00-2.00',20)
INSERT INTO rates
VALUES ('0.00-3.00',30)
INSERT INTO rates
VALUES ('0.00-4.00',40)

SELECT:-
Following are the select statement queries which includes joins etc, to show
the info in desired format.
1. Standard view of table vehicle_type
SELECT *
FROM vehicle_type
2. Standard view of table rates
SELECT *
FROM rates
3. Standard view of table vehicle_type
SELECT *
FROM vehicle_info
4. Vehicle type car
SELECT *
FROM vehicle_info
WHERE v_type = 1

11. 5. Vehicle type bike
SELECT *
FROM vehicle_info
WHERE v_type = 2
6. Rates of all vehicle
SELECT vehicle_info.register_no,rates.r_s
FROM vehicle_info
JOIN rates
ON vehicle_info.total_amount = rates.r_id
7. Rate of car LEX 1313
SELECT vehicle_info.register_no,r_s
FROM rates
JOIN
(vehicle_type JOIN vehicle_info
ON vehicle_info.v_type = vehicle_type.t_id)
ON rates.r_id = vehicle_info.total_amount
WHERE vehicle_info.register_no = 'LEX 1313'
8. Total amount calculated
SELECT SUM(r_s)AS Whole_total
FROM rates
JOIN vehicle_info
ON vehicle_info.total_amount = rates.r_id
INTERFACING:
Following are the images which of interfacing the project.
*This is optional as interfacing is not of this course.

12. First image shows the home page of the software which through which our
software will be operated, like if we want to enter the vehicle we click on
vehicle enter and another form will be open.
Second form opens and vehicle entering form is filled with some mannual
and some automatic enteries i.e date and time_in
This third form is for when vehicle is exiting we just enter the slip no and all
information is shown to us after receiving the money we only press save.
