Instructor: Trần Mạnh Hà
Requirement:
Car Manufacture Management (100 points). A simple car manufacture
management system manages multiple sets of data:
Car information contains identifier, title, type, year, color, manufacturer, options,
etc.
Manufacturer information contains identifier, name, nation, dealer, contact, etc.
Dealer information contains identifier, name, nation, address, contact, service,
etc.
Customer information contains identifier, name, address, car, year, dealer,
service, etc.
Several constraints need to be defined, at least cars belong to manufacturers,
manufacturers have dealers, customers possess cars and register dealers for
services, etc. This system allows managers to perform multiple functions on cars,
manufacturers, dealers and customers using the user interface.

III. User interface and function on data.
A. Homepage interface
HTML code:
<!DOCTYPE html>

<meta charset="utf-8">

<style>
body, html {
height: 100%;
margin: 0;
}
.bg {
/* The image used */
background-image: url("hinh-anh-o-to-con.jpg");
/* Full height */
height: 100%;
/* Center and scale the image nicely */
background-position: center;
background-repeat: no-repeat;
background-size:cover;

So, with this user interface, users can now choose what to do with the data, first let see
what happen if they want to show data.
B. Show data

Then they can show which table they want to show using the select box
and submit button.
PHP code:

First is the manufacturer data:
Second is the dealer data:
Third is the customer data:
Fourth is the car data:
And finally, the Distribute data:
This is the end of show function, next is the select data function.

In this interface, the user can select the information “who buy what car” by using the 2
type boxes and the result will be the join of 2 tables, customer and car:
For example:
-Find customer whose name like ‘mi’.
Find car whose name like ‘hy’
Find customer whose name like ‘ur’ or car name like ‘x4’
This is the end of this section. Next we will see if the user chooses to update data
D. Update data
In this section, we divide the function into add and change data.
HTML for add data, for simplicity, we will demonstrate only when the user wants to add
new car data:

The user now can add new data into the database.
For example:
C_ID= ‘44444’
M_ID=’10004’
CU_ID=’30013’
Carname=’BMW mui tran’
Type=’Convertible’
Seats=’9’
Price$=’888888’
Year=’2020’
Color=’Beige’
Status=’Really new’
Type_of_fuel=’Water’
Manufacture_date=’2020/1/1’
As you can see, the new information is added into the car table.
Next, let see what happens if the user wants to change data in the table.

The first selection box is where the user can choose the table, the type box bellow is for
the user to input ID of the column they want to change, in the attribute selection box,
there are all of the attribute in four main tables, and they can change that information
into new want by using the final type box.
For example:
Let change the price of the car into 1234567 where id=40002
Let change the customer’s VIP_Level into ‘normal’ where id=30012
Let change the manufacturer service into ‘domestic’ where id=10006
Finally, let change dealer’s top manager into ‘Tran Thanh’ where id=20001
That is the end of update data section. Finally, we come to the delete function.
E. Delete data

Using this interface, user can delete entire column with the ID in the type box. Because
of the constraint of foreign key, we demonstrate only the car table.
For example:
Let delete car table where id= 40003
