FOOD DISTRIBUTION MANAGEMENT SYSTEM 1
PREFACE
In recent years, an increasing number of industries and institutions are displaying information on
websites. This is being done mainly because they want to face the challenges of the new millennium,
which undoubtedly is computer independent.
In this era of modernity websites have become part and parcel of everyone’s day to day life. Even the
people for firms or institutions who are not associated with the websites are approaching the professionals
to develop website, which could reduce their tedious work like going and collecting information, giving
information with taking maximum time for traveling with expense and wasting the time. Websites are no
exception to this. With the help of websites it is very easy to collect information about any firm or
institution by just sitting in single computer with an internet connection.

1. INTRODUCTION:
" FOOD DISTRIBUTION ” is a desktop application designed to manage all the ration card
holder’s details, their family member’s details and food grains allotted to each card holder based the
number of family members. This system automates the manual record keeping system of food grains
distributed to all the card holders based on their card types.
The way our food is distributed cements in place production, consumption and trading practices
that destroy the environment harm animals and are deeply unjust.
In this era of computers and internet almost all the work in our day to day life is being
computerized. Using internet almost all works are carried out easily. Like we can say banking became
very easy with online banking, buying and selling became modernized by E-commerce web sites, people
came close to each other by social networking sites, sending messages to each other was also very
difficult and would take minimum 2 days to reach that is also modernized by Emails, chatting etc.
Here I am implementing a application known as “ FOOD DISTRIBUTION
MANAGEMENT SYSTEM ” .In this site the people of Karnataka can book the tickets for their
favorite movie just by logging on to our website. This Applications is developed to store and maintain all
the details of food distributed to the family.
All the tedious process will be minimized and even a common man can afford to do all these
things. Hence we can say that this application would be one more step towards modernizing the society.

 Three main components of Food Distribution :
 Transport infrastructure, such as roads, vehicles, rail transport, airports, and ports.
Food handling technology and regulation, such as refrigeration, and storage, warehousing.
Adequate source and supply logistics, based on demand and need.
 This report examines the impact of food distribution networks on our environment, economy,
culture and communities, and their contribution to climate change.
 We offer a sustainable vision for the future of food distribution, and provide a roadmap for
government, business and civil society to help get us there.
 Food Distribution Features & Functionality :
Food distribution software is a specialized form of warehousing and transportation management
software. As software, food distribution management system has overcome all these problems where the
data is completely secured and centralized, where the distribution happens properly and the remaining
supplies can also be easily verified. Thus keeping the data centralized and the interface made available to
all the users makes it easy and reliable to all the distributers and the government.

 Specific features include:
 Order Entry : Order entry initiates the entire food distribution cycle, so the system should be
able to store past customer orders and display them through sorting filters. This helps users
review customer history and automatically prepare “standard orders” made by customers on a
regular basis.
 Catch Weight Management : Since weight and quantities vary tremendously, a food distribution
program needs the ability to track the weights of meat and produce throughout the delivery and
distribution cycle and tie those to the ordering and accounting systems.
 Inventory Control: This includes lot tracking, which can integrate with barcode scanning or
radio frequency identification (RFID) implementations to note when and where certain items
were delivered, which will be particularly useful during a food recall.
 Delivery Management: Delivery management modules offer intelligent routing procedures that
result in faster delivery times. For food distribution, they’ll also need to incorporate special
transportation requirements, including refrigeration and handling care.
.

 PROBLEM DEFINITION :
Food distribution management system in present days is manually maintained in registers and the
cards are manually seen and verified, to distribute food for respective card holder. Maintaining these
records is heavy and insecure where the records can be damaged, altered and malpracticed. Thus the
problem is that the data is open and not centralized.
As software, food distribution management system has overcome all these problems where the
data is completely secured and centralized, where the distribution happens properly and the remaining
supplies can also be easily verified. Thus keeping the data centralized and the interface made available to
all the users makes it easy and reliable to all the distributers and the government.
Food distribution software helps to maintain the accounts of the firm along with sales in a details
and clear picture. Helps easy flow of work
No need of any paper work will be involved into the system; every aspect will be saved in the
software clear. Even the client details will be saved so that communication will be made very easily.

 EXISTING SYSTEM :
All the food distribution activities are managed manually through traditional means of record
keeping. The desired report generation is not possible and has to be carried out manually.
Records maintained and updated are not submitted back to the government. No centralized data, No data
security, Manual feed and alteration. Remaining grains records are not maintained, it has to be manually
calculated and maintained.
 Limitations of Existing System :
 Need more man power to keep a track on the work flow.
 More paper work is involved in the business.
 Takes lot of time to search for client details.
 Easy work will not be involved.
 Cannot keep a track on sales of the firm.
 More workers are needed, in order to take care of different departments.

 PROPOSED SYSTEM :
All the activities are managed by a set of user interfaces that takes care of data management
helping the users to easily carryout the tasks of food distribution. The proposed system also provides in
generation of reports based on different criteria with ease.
A window application is developed in such a way that software will reach all the objectives of the
firm in and proper way. Each and every departments will be assigned in the software so that there will be
a proper data of sales, transports and storages.

 Advantages of proposed System :
 It automates the management of data related to Food Distribution
 It helps in the generation on report based quires
 It provides the user in generation of reports based on different criteria.
 Uniformed friendly, courteous drivers insure on time deliveries.
 No man power required to keep a track of proper data of sales, transports and storages.
 Reduce time Compatibility.
 Food distribution software helps to maintain the accounts of the firm along with sales in a
details and clear picture.
 Helps in frequent deliveries and with our geographical reach we can make emergency
deliveries when required.

3 . INTRODUCTION TO VB.Net
 So what is Visual Basic?
The” Visual” part refers to the method used to create the graphical
User interface (GUI). Rather than writing numerous lines of code to describe
The appearance and location of interface elements, you simply add pre-built
Objects into place on screen. If you’ve ever used a drawing program such
As Paint, you already have most of the skills necessary to create an effective
User Interface.
The “Basic” part refers to the BASIC (Beginners All-purpose Symbolic
Instruction Code) language, a language used by more programmers than any
other language in the history of computing. Visual Basic has evolved from the original BASIC language
an now contains several hundreds statements, functions and keywords, many of which relate directly to
the windows GUI. Beginners can create useful applications by learning just a few of the keywords, yet the
power of the language allows professionals to accomplish anything that can be accomplished using any
other Windows programming language.
The Visual Basic programming language is not unique to Visual Basic. The
Visual Basic programming system Applications Edition included in Microsoft Excel, Microsoft Access,
and many other Windows applications uses the same language. The Visual Basic Scripting Edition
(VBScript) is a widely used scripting language and a subset of the Visual Basic language. The investment
you make a in learning Visual Basic will carry over to those other areas.
 VISUAL BASIC .NET IDE -2008 :

 Oracle SQL Plus:-
SQL is the standard language used to manipulate and retrieve data from these relational
databases. SQL enables a programmer or database administrator to do the following:
 Modify a database's structure.
 Change system security settings.
 Add user permissions on databases or tables.
 Query a database for information.
 Update the contents of a database.
 SQL was developed to service relational databases.

 The SQL has several parts :
 Data Definition language (DDL): provides commands for defining relation schemas, deleting
relations and modifying relational schemas.
 Interactive data-manipulation language (DML): includes a query language based on both the
relational algebra and the tupple relational calculus.
 View definition: The SQL DDL includes commands for defining views.
 Transaction control language: SQL includes commands for specifying the beginning and end of
transactions.
 Integrity: The SQL includes commands for specifying integrity constraints that the data stored in
the database should satisfy.
 Authorization: The SQL includes commands to specify the access rights to relations and views.
 Basic structure of SQL :
A relational database consists of a collection of relations, each of which is assigned a unique
name. SQL allows the use of null values to indicate that the value either is unknown or does not exist. It
allows the user to specify which attributes cannot be assigned null values.
The basic structure of an SQL expression consists of two parts

 Data Manipulation Language (DML) :
DML is a part of SQL that manipulates data in the database. The Statements you can use in DML are
SELECT, INSERT, UPDATE and DELETE.
 SELECT statement : This statement is used to select certain attributes from a table
 Format: SELECT <ATTRIBUTES> FROM <TABLENAME> WHERE CONDITION;
 INSERT statement : Enables the user to enter data directly into the table.
 Format: INSERT INTO TABLENAME (ATTRIBUTE NAMES…)
VALUES (ATTRIBUTE VALUES);
UPDATE statement
Enables to modify the data already stored in the table.
Format: UPDATE TABLENAME
SET COLUMNNAME=VALUE
WHERE CONDITION
DELETE statement
Enables you to remove selected rows of data from a single table.
Format : DELETE FROM TABLENAME
WHERE CONDITION

2. Data Control Language (DCL) :
The DCL provides security for your database .The command of DCL used most frequently is
COMMIT. COMMIT statement
The COMMIT command pertains to any transactions you make in the database. It
protects the database by restricting any operations that make changes to the database.
Format :
COMMIT;
Views
A view is a personalized presentation of data from one or more tables. View do not contain or store
data, but they take data from the tables on which they are based, called base tables. As the tables the
views can also be queried, updated, inserted and deleted, with some restrictions. All operations
performed in a view actually affect the database tables of that view.
Format: CREATE VIEW VIEWNAME AS
SELECT FIELDS
FROM TABLENAME
WHERE CONDITION
Indexes
An index is an optional structure associated to tables that increases the data recovery
performance. An index is created for one or more columns of a table. After being created, an index is
automatically updated and used by ORACLE.

Format : CREATE INDEX INDEXNAME ON TABLENAME (
NAMEOFTHECOLUMN ASC/DESC,..)
 Relational Database Management System
In an RDBMS, a database is considered to be a collection of interrelated data and programs. The data in a
database has to be related. The programs in a database perform the role manipulating this data. A database
management system is software that takes care of maintaining the database. It acts as the interface
between the database and the user.
A database that is designed on relational model of database is called a ‘Relational Database’ and
the software that helps maintain those database is called ‘Relational database Management System’. In
the relational data model, the data in a database is an organized in ‘relations’. A Relation is synonymous
with a ‘table’. A table consists of columns and rows, in which are referred to as fields and records in
DBMS terms and attributes and topples in RDBMS terms.

Oracle, version 8.0, is a Relational Database Management System. Being a component of the
professional and developer editions of Oracle.
Most database applications comprise of a ‘back-end’. The ‘Back-End’ part of the application
is the one which takes care of storing and retrieving the data the data. The ‘Front-End’ on the other hand,
provides a user-interface or a means by which the user can interact with the data in the back end. The user
of a particular application usually only interacts through the front-end. This comprises usually of ‘forms’,
which present the data in an attractive and user-friendly manner. It is these that are used to add, modify or
generally manipulate data in the tables.
Oracle SQL Plus acts as a back end as it provides tables where data can be stored. In
addition to this, it also acts as a front end.
Using Oracle therefore, forms can be created that act as the interface between the users the
tables.

DFD shows the use of the data pictorially. DFD represents the flow of the data between
transformations are process in the system. The DFD show the logical flow of data. These are used in
understanding a system and can be effectively used for partitioning during analysis. A DFD does not
represent procedural information.
In drawing DFD’s the designer has to specify the major transformations in the path of data
from input to output. It helps in the modular designing. It permits better documentation, control and
management of data about data. This also plays a major role in preventing errors, redundancies and
inconsistencies.
 Context Level data flow diagram:
The context level DFD shows the interaction of the system with the external
environment. It only depicts the inputs to the system and output from the system but it does not show how
they are transformed. The functional aspects of the system are not covered under context level DFD’s.

 Data Flow diagram Notations :
1. Functional Processing:
It is represented by an oval. The processing or main transaction are
specified by this notation.
 Data Flow:
It is represented by an arrow line and name of the data is specified by the side of
the line as label. This is used for data movement.

 Data Store:
It is represented by one open end rectangle. The database used in the system
are specified by this notation.
 Source or sink:
It is represented by one end rectangle. It is used for specifying from where
data comes and where it reaches.

 Steps required in DFD :
 Identify system, processing transformations. Transactions concerned with reading, validating and
formatting inputs.
 Identify input transformations. Transformations concerned with reading, validating and formatting
inputs.
 Identify output transformations. Transformations concerned with formatting and writing output.

6 . Entity Relationship Diagrams
 Definition :
An Entity-Relationship diagram is a data modeling technique that creates a graphical representation of
the entities, and the relationships between entities, within an information system. (View diagram).
 The three main components of an ERD are :
The entity is a person, object, place or event for which data is collected. For example, if you consider the
information system for a business, entities would include not only customers, but the customer's address,
and orders as well. The entity is represented by a rectangle and labeled with a singular noun.
 The relationship is the interaction between the entities. In the example above, the
customer places an order, so the word "places" defines the relationship between that instance of a
customer and the order or orders that they place. A relationship may be represented by a diamond
shape, or more simply, by the line connecting the entities. In either case, verbs are used to label the
relationships.
 The cardinality defines the relationship between the entities in terms of numbers. An entity may
be optional: for example, a sales rep could have no customers or could have one or many
customers; or mandatory: for example, there must be at least one product listed in an order. There
are several different types of cardinality notation; crow's foot notation, used here, is a common one.
In crow's foot notation, a single bar indicates one, a double bar indicates one and only one (for
example, a single instance of a product can only be stored in one warehouse), a circle indicates.

 Data process :
 A data process transforms data values.
Or
 If you open a process, you can either create a new DFD or open an existing DFD in which the
process is specified. The data flows of the opened process are connected in the new diagram to
the process with the name of the opened process. Vertices, and the flows and objects
connected to them, are transferred with the flows that are connected to the decomposed process.
If a data process has decomposition at a lower level, an asterisk is placed inside the ellipse. The
data process can be opened only if it has a name.
Data store :
Or
 A data store stores data passively for later access. A data store responds to requests to store and
access data. It does not generate any operations.
 A data store allows values to be accessed in an order different from the order in which they were
generated.
 Input flows indicate information or operations that modify the stored data such as adding or
deleting elements or changing values. Output flows indicate information retrieved from the store;
this information can be an entire value or a component of a value.

 The steps involved in creating an ERD are :
 Identify the entities.
 Determine all significant interactions.
 Analyze the nature of the interactions.
 Draw the ERD
 Entity Relationship Notations :
Peter Chen developed ERDs in 1976. Since then Charles Bachman and James Martin have added
some slight refinements to the basic ERD principles.
 Entity :
An entity is an object or concept about which you want to store information.
 Weak Entity :
A weak entity is an entity that must defined by a foreign key relationship with another entity as it cannot
be uniquely identified by its own attributes alone.
Entity
Entity

 Key attributes :
A key attribute is the unique, distinguishing characteristic of the entity. For example, an employee's social
security number might be the employee's key attribute.
 Multivalve attribute:
A multivalve attribute can have more than one value. For example, an employee entity can have multiple
skill values.
 Derived attribute:
A derived attribute is based on another attribute. For example, an employee's monthly salary is based on
the employee's annual salary.
 Relationships :
Relationships illustrate how two entities share information in the database structure.
Attribute
Attribute
Attribute
Relationship

 Tips for Effective ER Diagrams :
1) Make sure that each entity only appears once per diagram.
2) Name every entity, relationship, and attribute on your diagram.
3) Examine relationships between entities closely. Are they necessary? Are there any relationships
Missing? Eliminate any redundant relationships. Don't connect relationships to each other.
4) Use colors to highlight important portions of your diagram.
