1.1 ORGANIZATIONAL PROFILE
The system study entitled "Production Packaging System" is developed for
"Thangam Plastic Industries". It was established in the year 1961 in Salem.
This company is managed by Mr.K.C.Palanisamy, Chairman and Managing
Director and Mr.K.C.P.Shivaraman Joint Managing Director. This company is having
capacity for manufacturing best quality of packaging bags to export to various
countries such as U.S.A, U.K, and to many European countries. This company was
developed with the great effort.
Jumbo Bag, Circular Bag, U-Panel Bag, Baffle Bag, Tunnel Bag, Asbestos
Bag. The main objective of the project is to computerize the manual work done in
production. Now a days mostly all the business oriented concerns use computers.
Each and every thing in the production division must be kept up-to-date to carry over
the business successfully and efficiently. This system fabric cutting monitoring
system makes the production to be so as computerized and keep track of entire
function of the production division in a well organized manner.
The system concentrates on all the department of the entire production, their
functions, and the material details, manufacturing details. The system monitors the
production function and keeps track of entire things, which make the work to be look
easy and carry them with less error and mostly all the works are finished in time
efficiently by reducing the material wastage.

1.3 SOFTWARE FEATURES
Windows XP
WindowsXP has a new user system completely different from Windows98.This new system has been inherited from Windows NT/2000.
Now various users with independent profiles can be defined. This means that
each user can have different permissions that will allow him to carry out certain tasks.
Each user will have a different start menu and it's own My documents folder that will
be able to be protected by password. There also is a folder to which all the users have
access where the documents that want to be shared with other users can be placed.
For example, a Father user type that has access to all Internet and a Son user
type that is not allowed to certain violent or sexual webpages, can be defined.
To jump from one user's account to another is not necessary to turn off the
computer nor that a user closes what he was doing, one must simply initiate a new
session with another user and later it's possible to go back to the other session which
will remain in the same state it was left. The system handles the different active users
without interferences.
This way Microsoft intents to reduce illegal copying because a program can
only be used in one computer. This arises some questions that are difficult to answer:
What happens if a user updates his computer with a new processor or with a new hard
disk.

Visual Basic dot net
Visual Basic (VB) is a programming language based on the original DOS
language called BASIC (Beginners' All-purpose Symbolic Instruction Code).
VB.NET 2005, an offshoot of Visual Basic, is an object-oriented programming
language based on VB that is implemented using the Microsoft .NET framework. The
basic syntax of the Visual Basic language remains unchanged in VB.NET 2005, but
includes additional features such as structured exception handling and short circuited
expressions to enhance the infrastructure of the programming language. Developers
have found VB.NET to be controversial as some of the software and developmental
changes clash with the original language within VB and have caused compatibility
issues. Visual Studio .NET is the predominant integrated development environment
(IDE) that VB.NET developers employ.
The visual Basic is a widely used scripting language and a subset of the Visual
Basic language. The investment you make in learning Visual Basic will carry over to
these other areas. In developing applications with Visual Basic programming is about
new keywords and functions. I choose the topics that felt every programmer should
learn in order to master the language.
The Visual Basic programming language is not unique to Visual Basic. The
Visual Basic programming system, application edition included in Microsoft excel,
Microsoft access, Microsoft SQL server and many other windows applications use the
same language. There is nothing new in Visual Basic dot net in this area, but graphics
are such an important part of the language that the related techniques had to be
explained in detail.

2. SYSTEM STUDY
2.1 EXISTING SYSTEM
The system study manufactured Jumbo bags which are exported to countries
such as U.K, U.S.A and to many European countries. They are getting order from
various countries and process through the commercial department. This order comes
to execute after Confirmation. The Fabric cutting is the main part of the production.
They are done through manual calculation. This causes many waste sheets and lacks
in analysis of the report.
To update of the existing system we computerized the Fabric cutting section
using MS Visual basic dot net 2005 and SQL server 2005.Through this application we
can easily enter data, take a particular report, and can avoid wastage.
Another important existing system is time factor. It will not help the
management to solve the problem in time. The management could not act on any
issue; purchase or production unless getting the reports in time controls cannot be
used. The above said reasons are to overcome through this application.
The modules are
Jumbo Bag
Circular Bag
U-Panel Bag
Baffle Bag
Tunnel Bag
Asbestos Bag
MS-SQL server is a powerful multi-user RDBMS developed by Microsoft
Corporation. It can store and manipulate large amount of information and repetitive
tasks such as maintaining the roll slip no, fabric cutting roll no etc., Data can be
processed and meaningful reports can be generated easily.

2.2 SYSTEM DESIGN
System design centers the software engineering and applied science
regardless of the software process model that is used. Once the software
requirements have been analyzed and specified, tests that are in the building
and verifying the software is done. Each activity transforms information in a
number that ultimately results in validated computer software.
There are mainly three characteristics that serve as guide for evaluation
of good design,
The design must implement all of explicit requirements contained in theanalysis model, and it must accommodate all of the implicit
requirements desired by the customer.
The design must be readable, understandable guide for those who
generate code and for those who test and subsequently support the
software.
The design should provide a complete picture of software, addressing
the data, its functional and behavioral domains from the implementation
perspective.
System design is a process of planning a new system or to the complement
of the existing system. The design based on the limitation of the existing
system. The requirements specification gathered in the phase of system
analysis.

Entity Relationship Diagram
2.2.1.1 Context Analysis Diagram
A Context Diagram confines project scope to an agreed limit by obtaining
agreement from the customer on the data flows that are included in the scope of a
project. The Context Diagram focuses on relationships with external entities and
identifies the information that is exchanged between these external entities and the
business system under review. The external entities themselves are outside the scope
of the project but the data flows between the entities and the business system are
within the project scope.

2.2.1.2 Data Flow Diagram (DFD)
Data flow diagram is modeling tools that allow picturing a system as a
network of functional process to one another by data. They are also widely used for
representation of external and internal design specification.
Data Flow diagram is a graphical representation of the "flow" of data through
in information system. DFD's can also be used for the visulalization of data
processing. on a DFD's data items flow from an external data source or an internal
data store to an internal data store or an external data sink, via an internal process. a
DFD' provides no information about the timings of process, or about whether
processes will operate in sequence or in parallel. it is therefore quite different from a
flowchart which shows the flow of control through an algorithm, allowing to
determine what operation will be performed, in what order, and under what
circumstances but nt what kinds of data it be input to and output from the system over
where the data will come from and go to, where the data will be stoud. This is the
graphical representation of the data processes and used in the support of an
information system they describe system as collections of data that are manipulated
by functions. Data can be organised in several way. The basic elements are
Bubbles
Arrows
Open boxes
Input/output boxes

2.2.1.3 Entity Relationship Diagram
The Entity-Relation(ER) model is a conceptual data model that views
the real world as entities and relationships. A basic component of the model is
the Entity-Relationship diagram, which is used to visually represent data
objects. The model has been expended and today it is commonly used for
database design.
Features of ER Model are
It maps well to relational model.
It is simple and easy to understand with the minimum of training.
Therefore, database designer to communicate to the end user can
use the model.
In addition, the model can be used as a design plan by the
database to implement a data model in specific database management
software.
ER diagram is a model that describes the store layout of a system at high level
abstraction. The diagram is based on the three primitive concepts entities, relations
and attributes. E-R diagram enables to examine and highlight the data structure and
relationship between the data stores in data flow diagram based on the information
provided by the E-R diagram, the kind of keys or indexes needed to access the data
base can be determined. E-R diagram can express the overall logical structure of a
database graphically .E-R diagrams are simple and clear qualities that may well
account in large part for the widespread use of the E-R model. Such a diagram
consists of the following major components.
Rectangles which represent entity sets
Ellipses which represent attributes
Diamonds which represent relationship sets
Lines which link attributes to entity sets and entity sets to relationship sets

2.2.2. Physical Design
2.2.2.1. Database Design
The goal of database design is to generate a set if relations that allows storinginformation easily. The database is designed in relational model in which the data are
organized into entries and relation between them.
In our data flow diagrams, we have given names to data flows, process and
data stores. Although the names are descriptive of the data, they do not give details.
So the following DFD gives the details of the fields used. A data dictionary has many
advantages in improving analyst of user communication by establishing consistent
definitions of terms elements and procedures.
Types of Data Constraints
There are two types of dara constraints that can be applied to data being
inserted into a database table. One type of constraint is called an I/O constraint. The
other type of constraint is called a business rule constraint.
I/O Constraints
The input/output data constraint is further divided into two distinctly different
constraints.
The Primary Key Constraint
Here the data constraint attached to a column ensures:
That the data entered in the table column is unique across the entire
coloumn.
That none of the cells belonging to the table column are left empty.

2.2.2.2 Input Design
The input design is the process of entering data to the system. The input
design goal is to enter to the computer as accurate as possible. Here inputs are
designed effectively so that errors made by the operations are minimized. The inputs
are to the system have been designed in such a way that manual forms and the inputs
are coordinated where the data elements are common to the source document and to
the input. The input is acceptable and understandable by the users who are using it.
The quality of the system input determines the quality for system output. Input
specification describes the manner in which data entered the system processing.
Input design is the process of converting user-originated inputs to a computer
based format input data are collected and organized into group of similar data. Once
identified, appropriate input media are selected for processing.
The input design also determines the user to interact efficiently with the
system. Input design is a part of overall system design that requires special attention
because it is the common source for data processing error. The goal of designing input
data is to make entry easy and free from errors.

2.2.2.3. Output Design
The output design was done so that results of processing could be
communicated to the users. The various outputs have been designed in such a way
that they represent the same format that the office and management used to.
Computer output is the most important and direct source of information to the
user. Efficient, intelligible output design should improve the systems relationships
with the user and help in decision making. A major form of output is the hard copy
from the printer.
Output requirements are designed during system analysis. A good starting
point for the output design is the Data Flow Diagram (DFD).Human factors educe
issues for design involves addressing internal controls to ensure readability.

3. CONCLUSION
The world of computers is not static. It is always subject to change. The
technology today will become outdated the very next day. To keep abstract of the
technological improvements the system need refinements, so it is concluded, it will be
improved for further enhancements, whenever the user needs an additional feature
into it.
The system study title "Production Packaging System" has mostly all the
modules. It generates reports such as fabric roll component wise report, report based
on work order etc., will be very useful in analyzing the wastage of material where it
occurs and that can be recovered which will be useful in saving the material that leadsto more profit.
The system satisfies the all the requirements of the company and the
application is developed by advanced software Visual Basic dot net which is widely
used in all applications.
The system has been developed in Visual Basic dot net 2005 to reduce the
response time and ensure flexibility. The system also gives opportunity for further
development and enhancement of the existing system.
