6.6 Database: Database is most important part of my system to dynamically organizing data in database usually
interrelated data and set of program to access the data .The collection of data usually referred the
database contains information relevant of enterprise .The primary goals of database managements
system way to store and retrieve database that’s is the convenient and efficient .In this project I am
using PHP & MySql database in my system. MySql is an essential part of almost every open source
PHP application. MySql is a freely available open source relational database management system
(RDBMS) that uses structured query language (SQL). SQL is the most popular language for adding,
accessing and managing content in a database. It is most popular for its quick processing, reliability
and flexibility of use. I can use oracle but oracle is heavy weighted database for my system, that's why
I use MySql database in my system.

7.3Database
Database is the essential part of the existing my system .I am using PHP & Mysql existing database in
my web system .Why the big reason of using the database in my system I describe in the uppers site
of section of database. Every user and product information will save into database store information
when the user need .General user only see the product details and admin can insert and update, delete
products
Why I created database and its officially description in the next state of database??After creating the
database I am using Normalization techniques to store data dynamically for save space. Now
discusses normalization is techniques efficiently organizing data in database there are two goal this
process eliminating redundant data and ensuring data dependencies make sense storing related data
in database .Both of worthy goals as they reduce amount of space a database consumer ensure That
data are logically stored

public $Err;//Veriable helps to error message contains
Protected function Connect () { //connect function are created if we call connect then
automatically database are connected and protected only child class uses this property
From any child class
mysql_connect("localhost", "root", "");//localhost host name and root means
user and “”this property contains password of user
mysql_select_db("ecom_four");//selected database name for connect
}
}
?>///ending php tags
7.7. Essential Coding Insert Update Delete
Essential element of my system is divided into 3 parts user parts admin panel, visitor panel.
Admin user are the super user of my system he gets biological all privilege of my system admin
can create operator to help the any type of work such as insert update and delete operation
admin can delete operator and admin generally insert the new product delete old product and
update any type of error and also handling the user visitor and registered user. Registered user
sees the product description cannot do any action and user can purchase product purchase
system now under construction .Visitor only the see the product details
27
7.7. 1. Inserting Data
I need to insert product data, city , country category, subcategory, user, and purchase data, and
Comments data of specific products this insertion coding is given bellow :
public function Insert() {
$this->Connect();
$sql = "insert into city (name, countryid)
values
('".MS($this-
>Name)."',
'".MS($this-
>CountryId)."')";
if(mysql_query($sql)) {
return true;
}
$this->Err = mysql_error();
return false;
}
28
7.7. 2. Updating Data
public function Update() {
$this->Connect();
$sql = "update city
set
name = '".MS($this->Name)."',
countryid = '".MS($this-
>CountryId)."'
where
id = '".MS($this->Id)."'";
if(mysql_query($sql)) {
return true;
}
$this->Err = mysql_error();
return false;
}
29
7.7.3Deleting Data
Delete data: Where admin need to delete old data ,we have to require following
are given code .
public function Delete() {
$this->Connect();
$sql = "delete from city
where
id = '".MS($this->Id)."'";
if(mysql_query($sql)) {
return true;
}
$this->Err = mysql_error();
return false;
}
30
8. 7.4 View Data
View data: Admin need to view data .following given are code of view
public function Select()
{
$this->Connect();
$a = "";
$sql = "select city.id, city.name, country.name
from city, country
where city.countryid = country.id";
if($this->Name != "") {
$sql .= " AND city.name LIKE '%".MS($this-
>Name)."%'";
}
if($this->CountryId > 0) {
$sql .= " AND city.countryid = '".MS($this-
>CountryId)."'";
}
$sql .= " ORDER BY city.name ASC";
//echo $sql;
$sql = mysql_query($sql);
while($d = mysql_fetch_row($sql)) {
$a[] = $d;
}
return $a;
}
31
8.1Exception
Many exceptions would have been caught by the compiler’s default exception
handler in my programs, if they were not caught by me. A list of total
exceptions considered for my program is given below in a table with their
reasons.
Name of the Exception Reason to Happen
NumberFormatException Input format conflicts
NullPointerException No input given
ClassNotFoundException Specific class is not found
SQLException Database sql error
UnsupportedAudioFileException Audio file is not supported
IOException Input Output file error
LineUnavailableException Line is not available
32
8.2Error handling:
I caught all the exceptions given in the table above. Among those exceptions, some are caught
in the background of the program. It will not show any message on the screen, when the
exceptions are caught and will simply run without the part for which the exception is caught.
However, when a user inputs invalid number, invalid in the sense that it is not a number at all, a
number format exception would be caught at that time, and this time it will show a message to
the user that it is an invalid input, the same way it display message when the input given is a
number but out of the product range. User will not even recognize that it was an error caught by
the system.
Catch of this exception is more or less same in almost all the classes (Stewart, A. 2004, page
326-335). The code I used is given below.
catch(NumberFormatException enf){
descrip.setText("Invalid Number");
proNum1.setText("");
playSound2();
}
The playSound () method here is for playing the sound described previously and that is why
everything will look like same as it is just an invalid number.
For the DBhandler class, when connecting the database to the program, two of the exceptions
must be caught otherwise compiler would complain about it. Those two exceptions are
ClassNotFoundException and SQLException. The second one is also necessary for all the
methods in this class when I needed to close the result set every time.
For playing sound, those exceptions defined in the table above are needed to be thrown.

9.Testing
9.1 Overview
Testing is the process of evaluating a system or its component(s) with the intent to find that
whether it satisfies the specified requirements or not. This activity results in the actual,
expected and difference between their results. In simple words testing is executing a system
in order to identify any gaps, errors or missing requirements in contrary to the actual desire or
requirements.
9.2 Scope
Testing depends on the source code but reviewing requirements and developing test cases is
independent from the developed code. Finding bugs in the Software is the task of testers.
Developers are only responsible for the specific component or area that is assigned to them
but testers understand the overall workings of the software, what the dependencies are and
what the impacts of one module on another module are. This section of the document
describes the overall testing activities with test case.

11. Conclusion
In the future, we will add more option and make this online computer shop more effective.
Adding a purchase feature to this system will be another change .We are also thinking about
card system to purchase products users friendly including more efficient and modern
facilities.
