ABSTRACT
This project is a Java Swing Application that displays and maintains a list of people with pending
payments and calculates the interest upon the late payments based on a pre-defined formula. It
further maintains an individual payment table for each client. The front end is created in
NetBeans IDE 7.2.1 whereas the back end is created using MySQL workbench.
The application makes tables by retrieving data from MySQL tables.
The Database table that is created, is in MySQL workbench. This report also contains an
extensive discussion on the work that was done on MySQL which includes the features of the
DBMS and also a few snapshots that show the functions of the commands or queries that are
commonly used.

CHAPTER 1
INTRODUCTION
1.1 OBJECTIVE:
The objective of this Report is to put forward the work that was carried out on MySQL and
Java Swing application during the span of one month of Internship.
The First part of the Implementation part deals extensively with the introduction, features and
working of MySQL. The snapshots that are provided, show the queries that are used for the
creation of a table, followed by the selection, insertion, deletion, import and export of the data in
the table.
The second part then shows the Swing application in its form, its connection with the database
and the Table creation. This part of the Report involves syntax and functions used for the
execution of the entire project.

CHAPTER 2
SYSTEM DESCRIPTION
2.1 MODULE 1:
Working with MySQL:
The MySQL™ software delivers a very fast, multi-threaded, multi-user, and robust SQL (Structured
Query Language) database server. MySQL Server is intended for mission-critical, heavy-load
production systems as well as for embedding into mass-deployed software. Oracle is a registered
trademark of Oracle Corporation and/or its affiliates. MySQL is a trademark of Oracle Corporation
and/or its affiliates, and shall not be used by Customer without Oracle's express written
authorization. Other names may be trademarks of their respective owners.
MySQL Workbench is a graphical tool for working with MySQL Servers and databases. MySQL
Workbench fully supports MySQL Server versions 5.1 and above. It is also compatible with
MySQL Server 5.0, but not every feature of 5.0 may be supported. It does not support MySQL
Server versions 4.x.
MySQL Workbench functionality covers five main topics:
 SQL Development: Enables you to create and manage connections to database servers. Along
with enabling you to configure connection parameters, MySQL Workbench provides the
capability to execute SQL queries on the database connections using the built-in SQL Editor.
 Data Modeling (Design): Enables you to create models of your database schema graphically,
reverse and forward engineer between a schema and a live database, and edit all aspects of
your database using the comprehensive Table Editor. The Table Editor provides easy-to-use
facilities for editing Tables, Columns, Indexes, Triggers, Partitioning, Options, Inserts and
Privileges, Routines and Views.
 Server Administration:Enables you to administer MySQL server instances by administering
users, performing backup and recovery, inspecting audit data, viewing database health, and
monitoring the MySQL server performance.

 Data Migration: Allows you to migrate from Microsoft SQL Server, Microsoft Access,
Sybase ASE, SQLite, SQL Anywhere, PostreSQL, and other RDBMS tables, objects and data
to MySQL. Migration also supports migrating from earlier versions of MySQL to the latest
releases.
2.2 MODULE 2:
Basic Java Programming :
Java is a general-purpose computer programming language that is concurrent, class-based, object-
oriented, and specifically designed to have as few implementation dependencies as possible. It is
intended to let application developers "write once, run anywhere" (WORA), meaning
that compiled Java code can run on all platforms that support Java without the need for
recompilation. Java applications are typically compiled to bytecode that can run on any Java virtual
machine (JVM) regardless of computer architecture. As of 2015, Java is one of the most popular
programming languages in use, particularly for client-server web applications, The language derives
much of its syntax from C and C++, but it has fewer low-level facilities than either of them.
JDBC is a Java database connectivity technology (Java Standard Edition platform) from Oracle
Corporation. This technology is an API for the Java programming language that defines how a client
may access a database. It provides methods for querying and updating data in a database. JDBC is
oriented towards relational databases. A JDBC-to-ODBC bridge enables connections to any ODBC-
accessible data source in the JVM host environment.
JDBC allows multiple implementations to exist and be used by the same application. The API
provides a mechanism for dynamically loading the correct Java packages and registering them with
the JDBC Driver Manager. The Driver Manager is used as a connection factory for creating JDBC
connections.
JDBC connections support creating and executing statements. These may be update statements
such as SQL's CREATE, INSERT, UPDATE and DELETE, or they may be query statements such as
SELECT. Additionally, stored procedures may be invoked through a JDBC connection. JDBC
represents statements using one of the following classes:
 Statement – the statement is sent to the database server each and every time.

 PreparedStatement – the statement is cached and then the execution path is pre-determined
on the database server allowing it to be executed multiple times in an efficient manner.
 CallableStatement – used for executing stored procedures on the database.
Update statements such as INSERT, UPDATE and DELETE return an update count that indicates
how many rows were affected in the database. These statements do not return any other
information.
Query statements return a JDBC row result set. The row result set is used to walk over the result
set. Individual columns in a row are retrieved either by name or by column number. There may be
any number of rows in the result set. The row result set has metadata that describes the names of
the columns and their types.
There is an extension to the basic JDBC API in the javax.sql .
JDBC connections are often managed via a connection pool rather than obtained directly from the
driver.
Swing is a GUI widget toolkit for Java. It is part of Oracle's Java Foundation Classes (JFC) —
an API for providing a graphical user interface (GUI) for Java programs.
Swing was developed to provide a more sophisticated set of GUI components than the
earlier Abstract Window Toolkit (AWT). Swing provides a native look and feel that emulates the look
and feel of several platforms, and also supports a pluggable look and feel that allows applications to
have a look and feel unrelated to the underlying platform. It has more powerful and flexible
components than AWT. In addition to familiar components such as buttons, check boxes and labels,
Swing provides several advanced components such as tabbed panel, scroll panes, trees, tables, and
lists.
Unlike AWT components, Swing components are not implemented by platform-specific code.
Instead, they are written entirely in Java and therefore are platform-independent. The term
"lightweight" is used to describe such an element.

CHAPTER 3
IMPLEMENTATION
3.1 Working of the project:
The project is based on the concept of creation of partial payment tables in MySQL for every
entry in the late payment database
The application allows the user to add new transactions, and for each transaction there is a new
SQL table that is created due to query execution. This new table allows the database to accept
partial payments for each transaction in the main table.
The application offers other basic features for entering and deleting from the pending list as well
as addition and deletion of partial payments
3.2 Working in MySQL:
Database creation in MySQL:
Query
mysql> CREATE DATABASE paramount;

Transaction Table creation in MySQL:
CREATE TABLE `paramount`.`pending_list` ( `Sr_no` INT NOT NULL COMMENT '',
`Party_Name` VARCHAR(45) NOT NULL COMMENT '', `Sale_Date` DATE NOT NULL
COMMENT '', `Due Date` DATE NOT NULL COMMENT '', Àmount` FLOAT NOT NULL
COMMENT '', `Rate` INT NOT NULL COMMENT '', `Quantity` FLOAT NOT NULL
COMMENT '', Ìnterest` FLOAT NOT NULL COMMENT '', PRIMARY KEY (`Party_Name`)
COMMENT '');
Using table import wizard in MySQL workbench
Import data into the table pending_list from ‘pending_list.csv’
Partial payment Table creation in MySQL:
CREATE TABLE `paramount`.àmit` ( `Sr_no` INT(11) UNIQUE NOT NULL COMMENT '',
Àmount` FLOAT NOT NULL COMMENT '', `Rate` INT(11) NOT NULL COMMENT '',
`Quantity` FLOAT NOT NULL COMMENT '', `Recieved_Date` DATE NOTNULL
COMMENT '', `No_of_Late_Days` INT(11) NOT NULL COMMENT '',

`Per_kg_per_day_interest` FLOAT NOT NULL COMMENT '', `Due_Date` DATE NULL
COMMENT '', PRIMARY KEY (`Sr_no`) COMMENT '');
Using table import wizard in MySQL workbench
Import data into the table pending_list from ‘amit v.k.csv’

3.3 Database ConnectionSyntax:
To create a connection between the front end and the database, a few files have to be
imported. These required files and the syntax in which they are to be imported in a JSP file
are given below:
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import net.proteanit.sql.DbUtils;
After importing the required files, the next important line is to initialize the JDBC driver
and the URL
static final String JDBC_DRIVER = "com.mysql.jdbc.Driver";
static final String DB_URL = "jdbc:mysql://localhost/paramount";
After that the username and password are defined to log in.
static final String USER = "root";
static final String PASS = "mufaddal";
To create a connection to the database, the DriverManager file is used. The syntax is as per
given below:
Connection conn = null;

Statement stmt = null;
Class.forName("com.mysql.jdbc.Driver");
The conn is an object that is used to create the connection between the MySQL database
paramount. The username and password of the MySQLSQL software are followed by the
name of the database.
Then the java database is allowed to access the tables using the credentials
conn = DriverManager.getConnection(DB_URL,USER,PASS);
The data is then inserted into the table , with the help of the following statement:
sql ="SELECT * FROM `paramount`.`"+party+"`;";
This String is then executed with the help of:
ResultSet rs = stmt.executeQuery(sql);
Then the obtained table is matched to the data type used in Java
jTable1.setModel(DbUtils.resultSetToTableModel(rs));

3.4 Queries executedin Java for different functions
Deleting a record
DELETE FROM `paramount`.`pending_list` WHERE Party_Name='"+party+"';"
Adding a record and creating a partial payment table
INSERT INTO pending_list
"+"VALUES('"+rc.sr_no+"','"+rc.party_name+"','"+rc.sale_date+"','"+rc.due_date+"','"+rc.a
mount+"','"+rc.rate+"','"+rc.quantity+"','"+rc.interest+"','"+rc.status+"')";
CREATE TABLE `paramount`.`"+table_name+"` ("+
"`Sr_no` INT(11) UNIQUE NOT NULL,"+
"`Amount` FLOAT NOT NULL,"+
"`Rate` INT(11) NOT NULL,"+
"`Quantity` FLOAT NOT NULL,"+
"`Recieved_Date` DATE NOT NULL,"+
"`Due_Date` DATE NULL,"+
"`No_of_Late_Days` INT(11) NOT NULL,"+
"`Per_kg_per_day_interest` FLOAT NOT NULL,"+
" PRIMARY KEY (`Sr_no`));
Viewing Pending List
sql = "SELECT * FROM pending_list";

Deleting a partial payment
DELETE FROM `paramount`.`"+party+"` WHERE Sr_no='"+i+"';"
Adding a partial payment
INSERT INTO `paramount`.`"+party+"` VALUES('"
+data.sr_no+"','"+data.amount+"','"+data.rate+"','"
+data.quantity+"','"+data.recd_date+"','"+data.due_date
+"','"+data.no_days+"','"+data.per_day_interest+"')"
Viewing a payment table
3.5 Layout of the application
3.4.1 Homepage
This is the first menu that appears at the start of the application. It allows the
user to view all the transactions. It also allows the user to add new transactions
and delete existing transactions.

3.4.2 Delete recordscreen
It takes the party name to be deleted from the user and executes a query in the background to
delete that record

3.4.3 Add Recordscreen
It takes the attributes from the user for the record to be added into the table
It also creates another table for the newly created record for future partial payments.
3.4.4 View Pending List screen
This screen gives all the existing transactions in the database in the form of a table

3.4.5 Delete payment screen
It takes the Party name and the Payment ID to be deleted from the user
3.4.6 Add payment screen
It takes the payment data from the user to execute a query in the background to add the
payment in the database.

3.4.7 View Payment Screen
It takes the Party Name from the user to execute a query in the background to search the party in
the database.
3.4.8 View payment table
It views all the processed payments with their calculated interest in a table.
