AAbbssttrraacctt Cafeteria Management System is computer that system that help cafeteria to manage

their cafeteria dairy process, such as order, reservation, redemption and etc. The entire

system consists of back end and front end, which back end was an offline application

and front end was a web site. The offline application allow cafeteria to manage the

cafeteria information and managing the dairy process such as seat admission and

order. And the system allow cafeteria to manage their meal menu and promotion. And

all the updated meal menu and promotion will be show on the web page automatically

upon the completion of updating.

Cafeteria Management System is developed by using Microsoft Visual 2010. The

offline application is developed by using VB.net with object-oriented programming

method, and the web site is developed by using c#. The database is design and

managed by using Microsoft SQL 2007.

The current cafeteria is currently working by using manual way which means fully

paperwork, which consist a lot of man power and time in managing the record and

dairy process. And human mistake is unavoidable while the workload is increasing.

Therefore they request for the developing of Cafeteria Management System, which

making their dairy process form paperwork into automate system. Cafeteria

Management System other than replace their manual dairy work such as enter order,

make reservation and payment, also including new function such as online reservation

and ordering, online meal and promotion viewing, report generating and reservation

notification.

With the developing of Cafeteria Management System, it increases the efficiency of

Cafeteria and improves the service, automate system process able reduce dairy work

error, also save time and also cost in long term.

System Planning


Project 1

11..00 SSyysstteemm PPllaannnniinngg

This chapter will provide the overview of the project planning in the system which

include project aims and objectives, company background, project scope, project

schedule, and outline of approach/Methodology Used.

1.1 Project Aims and Objectives

The system will helps to fasten the respond time when doing daily transaction.

Customers or members enquiries will be responding in an efficient way because the

system can help to keep track of the member record quickly.

The system also can help to save the manpower in maintaining the paperwork, record

that kept in system will save the paper cost, and manpower cost that normally require

more staff to take care of the paper document and using database also save the place

to store the document.

The system make the payment process become easier and faster.

Appointment becomes flexible and easy to maintain. The member can make

appointment by phone call the staff of cafeteria or using the online system making the

appointment for their dinning time and food they need.

Online feedback can let customer to rating for the meal that they eat. The meal rating

also can be a kind of reference when customers make meal ordering. This may help to

improve the sales of the cafeteria.

The system allows the time and set meal arrangement for whole week and makes the

appointment become easier.

The system help the cafeteria to keep track the membership status of the member.

Thus, it helps the cafeteria to increase the income and keep track the popularity of

cafeteria.

1.5 Outline of approach/Methodology Used

Microsoft Visual 2010 had been used in developing the system, and Microsoft SQL

2007 had been use for database management of the system, which is build-in database

of Microsoft Visual 2010. Vb.net is used for the offline application development and

c# is adapted on web application development. 3 Tier Object Oriented approaches had

been used on offline application for easier maintenance of the system. And SDLC

method had been use in designing the system requirement and work flow.

Requirements Analysis


Project 10

22..00 RReeqquuiirreemmeennttss AAnnaallyyssiiss

This chapter is going to analysis the requirement of the system and what function the

system shall be able to provide in order to fulfill the user need. Fact will be collect

and gather by understanding the user need.

2.1 Fact Gathering

As U Like Café is currently using the old type of management way, this is though

paper work. Everything is done manually by using paper recording including order,

reservation, payment, staff and member information recording. And that’s no personal

web site for cafeteria.

Because everything thing is done by using manual work, which is merely using pen to

record on book or paper, therefore more manpower and time will be consume. And

manual paper-work may cause more mistake compare to automate system method.

And cafeteria staff had to always aware of the order and reservation list, to make sure

every reservation and order will de deliver on time, without the help of auto

notification.

And information maintenance will be hard when information is recorded in paper

work. Paper-work information storing require more and more space while the

business size is becoming bigger, and will be time-consuming and difficult to retrieve

information from a pile of paper work.

Therefore, a system that able to solve the current problem is require, which mean a

system that able to provide easier information maintenance, order and reservation

management, and also include external function such as report generating.


Project 11

2.1.1 Background Reading

It’s a process to gain more understanding about our customer such as their company

background, objective, business core and so on. By gaining the understanding of their

company such as company policy and company rules, it eases developer to building up

the business rules when designing the database and coding. Through the reading, we

understanding all their business need and also find out that they are actually using

manual paperwork for management currently.

2.1.2 Interview

After the background reading, we also interviewed Ms Lim, the Manager of As U Like

Café. Though the interview, we gather all problems that’s facing by their current

management, such as troublesome in maintenance the old record, high error rate on

documentation, time consuming and so on. In order to gain more understanding about

the need of system, Ms Lim agreed us to collect information from cafeteria staff by

using questionnaire technique. Other than understanding the current problem facing by

the current management in the interview, we also discuss about the new function

request by them such as redemption module and online menu viewing.

44..00 PPrrooggrraammmmiinngg This chapter will show the coding part of Cafeteria Management System, and some

explanation on how the logic works.

4.1 Three Tier Architecture

Cafeteria Management System is developed by adapting three tier object-oriented

programming method. Three Tier Architecture is separated to three sections which are

graphic user interface class, problem domain class and data access class. Each of the

sections has different function and role

4.1.1 Graphic User Interface Class

This class contains the object and code which build up the user interface. It

communicates with problem domain class to pass in and receive necessary parameter

from database. Below are the examples of code of graphic user interface class that

extract from cafeteria management system.

Private Sub btnAddMeal_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)

Handles btnAddMeal.Click

If txtMealID.Text = "" Then

ErrorProvider1.Clear()

ErrorProvider1.SetError (txtMealID, "Please enter Meal ID.")

Else

ErrorProvider1.Clear()

If Food.validate(txtMealID.Text) = "yes" Then

aPromotion = Promotion.addMeal(txtMealID.Text)

listMealID.Items.Add(aPromotion.pMealID)

listMealName.Items.Add(aPromotion.pMealName)

Else

MessageBox.Show("Invalid Meal ID", "Invalid Meal ID")

End If

End If

End Sub


Project 85


Project 86

4.1.2 Problem Domain Class

This class act as a middle tier between graphic user interface class and data access class

to control the functionality of the application. It playing an important role for gets and

set thevalue passing between graphic user interface class and data access class. Below

are the examples of code of problem domain class that extract from cafeteria

management system.

Public Class Promotion

Private promotionID As String

Private name As String

Private price As Double

Private descript As String

Private dateStart As String

Private dateEnd As String

Private RetrievePhoto As System.IO.MemoryStream

Private SavePhoto As String

Public Sub New()

End Sub

Public Sub New(ByVal aPromotionID As String, ByVal aName As String, ByVal aPrice As

Double, ByVal aDescript As String, ByVal aDateStart As String, ByVal aDateEnd As

String, ByVal aRetrievePhoto As System.IO.MemoryStream, ByVal aSavePhoto As String)

pPromotionID = aPromotionID

pName = aName

pPrice = aPrice

pDescript = aDescript

pDateStart = aDateStart

pDateEnd = aDateEnd

pRetrievePhoto = aRetrievePhoto

pSavePhoto = aSavePhoto

End Sub

Public Sub New(ByVal aMealID As String, ByVal aMealName As String)

pMealID = aMealID

pMealName = aMealName

End Sub

Public Property pMealName() As String

Get

Return mealName

End Get

Set(ByVal value As String)

mealName = value

End Set

End Property


Project 87

End Class


Project 88

4.1.3 Data Access Class

This class will handle every operation that’s regarding to database such as data retrieve

and data saving. Below are the examples of code of data access class that extract from

cafeteria management system.

Imports System.Data.SqlClient

Public Class PromotionDA

Shared Conn As New SqlConnection("Data

Source=.\SQLEXPRESS;AttachDbFilename=C:\Users\NG\Desktop\FYP Final\backup v12\Cafeteria

Management System\Cafeteria Management System\Cafeteria Management

System\Database.mdf;Integrated Security=True;User Instance=True")

Shared aPromotion As Promotion

Public Shared Sub Delete(ByVal promotionID As String)

Dim sqlDelete As String

sqlDelete = "DELETE FROM Promotion WHERE Promotion_ID = '" & promotionID & "'"

Try

Initialize()

Dim adpApp As New SqlDataAdapter()

adpApp.DeleteCommand = New SqlCommand(sqlDelete)

adpApp.DeleteCommand.Connection = Conn

adpApp.DeleteCommand.ExecuteNonQuery()

Catch e As Exception

MessageBox.Show(e.Message)

Finally

Terminate()

End Try

End Sub


Project 89

4.2 Common Add, Edit and Delete

Add, edit and delete coding is one three of the most common code used in the system.

The code were basically the same, the only different of these code in different module is

amount of object involve, object name and sql statement. Below is the example code of

each function:

4.2.1 Add Function

Public Shared Sub AddNew(ByVal aFood As Food)

Meal_ID = aFood.Food_MealID

Name = aFood.Food_Name

Type = aFood.Food_Type

SavePhoto = aFood.Food_SavePhoto

Price = Double.Parse(aFood.Food_Price)

Descript = aFood.Food_Description

Try

Initialize()

Dim command As New SqlCommand("INSERT INTO Food VALUES ('" & Meal_ID & "', '" &

Name & "','" & Type & "', @Picture,'" & Price & "', '" & Descript & "')", Conn)

Using picture As Image = Image.FromFile(SavePhoto)

Using stream As New IO.MemoryStream

picture.Save(stream, Imaging.ImageFormat.Jpeg)

command.Parameters.Add("@Picture", SqlDbType.VarBinary).Value =

stream.GetBuffer()

End Using

End Using

command.ExecuteNonQuery()

Dim cmdSurvey As New SqlCommand("INSERT INTO Survey VALUES ('" & Meal_ID & "',

'0','0','0','0','0','0')", Conn)

cmdSurvey.ExecuteNonQuery()

MessageBox.Show("New meal menu save successfully.", "Save Successfully")

Catch ex As System.IO.FileNotFoundException

MessageBox.Show("Invalid path for image uploading.", "Error!")

Finally

Terminate()

End Try

End Sub


Project 90

4.2.2 Edit Function

Editing and text information and image separate to two parts. For module that involve

image editing, the system will check is that any image path is passed in to data access

class, if yes, the system will replace the database image according to the image path,

else nothing will be change to the existing image.

Public Shared Sub Update(ByVal aFood As Food)





Price = aFood.Food_Price


Dim sqlUpdate As String = "Update Food SET name ='" & Name & "',type='" & Type &

"' ,price ='" & Price & "' ,description ='" & Descript & "' WHERE Meal_ID = '" & Meal_ID

& "'"

Initialize()

Dim adpFoodup As New SqlDataAdapter()

adpFoodup.InsertCommand = New SqlCommand(sqlUpdate)

adpFoodup.InsertCommand.Connection = Conn

adpFoodup.InsertCommand.ExecuteNonQuery()

MessageBox.Show("Update Successfully!")

Terminate()

If SavePhoto <> "" Then

Try

Dim command As New SqlCommand("UPDATE Food SET photo = @Picture WHERE

Meal_ID = '" & Meal_ID & "'", Conn)





stream.GetBuffer()

End Using

End Using

Initialize()


Catch ex As System.IO.FileNotFoundException

MessageBox.Show("Invalid path for image uploading.", "Error!")



Project 91

MessageBox.Show("No Image is selected for upload.", "Error!")

Finally

Terminate()

End Try

End If

End Sub


Project 92

4.2.3 Delete Function

Public Shared Sub Delete(ByVal MealID As String)

Dim sqlDelete As String

sqlDelete = "DELETE FROM Food WHERE Meal_ID = '" & MealID & "'"

Try

Initialize()

Dim adpApp As New SqlDataAdapter()

adpApp.DeleteCommand = New SqlCommand(sqlDelete)

adpApp.DeleteCommand.Connection = Conn

adpApp.DeleteCommand.ExecuteNonQuery()


MessageBox.Show(e.Message)

Finally

Terminate()

End Try

End Sub


Project 93

4.3 Auto ID Generation

Below is the code use for auto ID generation. This code will get the last ID in the

particular database, grab the ID number and generate the next ID. If no ID is existed, it

will proceed to generate the 1st ID (number) which is 0001.

Public Shared Function GenerateID() As String

Initialize()

Dim AutoID As String

Dim sequence As Integer

Dim cmd As New SqlCommand("Select Top 1 Meal_ID from Food Order By Meal_ID DESC",

Conn)

Dim adpFood As New SqlDataAdapter(cmd)

Dim dsFood As New DataSet("Food")

Try

adpFood.Fill(dsFood, "Food")

AutoID = dsFood.Tables("Food").Rows(0).Item(0).ToString.Substring(2).Trim

sequence = Convert.ToInt32(AutoID)

sequence = sequence + 1

If sequence.ToString.Length = 1 Then

CurrentID = "ML000" & sequence

ElseIf sequence.ToString.Length = 2 Then


ElseIf sequence.ToString.Length = 3 Then


End If

Catch ex As Exception

CurrentID = "ML0001"

Finally

Terminate()

End Try

Return CurrentID

End Function


Project 94

4.4 Upload Image to database

In graphic user interface class, a button will be inserting with browsing code, and the

code with OFD component and paste in a label. With the path available, the data access

code able to covert the image into bit file and store into database. Below is the code used

for image uploading in offline application which is vb.net language.

Graphic User Interface Class

Private Sub btnBrowse_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)

Handles btnBrowse.Click

OFDmenu.Title = "Get Image"

OFDmenu.Filter = "Bitmap Files|*.bmp|Gif Files|*.gif|JPEG Files|*.jpg"

OFDmenu.DefaultExt = "bmp"

OFDmenu.FilterIndex = 1

OFDmenu.FileName = ""

OFDmenu.ShowDialog()

End Sub

Private Sub OFDmenu_FileOk(ByVal sender As System.Object, ByVal e As

System.ComponentModel.CancelEventArgs) Handles OFDmenu.FileOk

txtImageFile.Text = OFDmenu.FileName

End Sub

Data Access Class

Public Shared Sub AddNew(ByVal aFood As Food)





Price = Double.Parse(aFood.Food_Price)


Try

Initialize()

Dim command As New SqlCommand("INSERT INTO Food VALUES ('" & Meal_ID & "', '"

& Name & "','" & Type & "', @Picture,'" & Price & "', '" & Descript & "')", Conn)





stream.GetBuffer()

End Using


Project 95

End Using


End Sub


Project 96

4.5 Display Image from database (Offline Application)

For some module that involved image in information, image displaying is needed. Below

is the code for abstract image from sql database and display it with picture box

component.

Graphic User Interface Class

Dim ImageFromDB As New Bitmap(aFood.Food_RetrievePhoto)

MenuPictureBox.Image = ImageFromDB

txtPrice.Text = aFood.Food_Price

txtDescription.Text = aFood.Food_Description

Data Access Class

If dsFood.Tables("Food").Rows.Count > 0 Then

Dim foodRow As DataRow

foodRow = dsFood.Tables("Food").Rows(0)

Dim newMstream As New System.IO.MemoryStream(CType(foodRow.Item("photo"), Byte()))

UploadPhoto = newMstream

SavePhoto = Nothing

aFood = New Food(Meal_ID, Name, Type, UploadPhoto, Price, Descript, SavePhoto)

End If


Project 97

4.6 Display Image from database (Web Page)

To display image in c#, ahsx page is needed to play as a role to store temporary image,

because c# only allow image to be show by using image path. Below is the code needed

to retrieve image from sql database into ashx page. And this ashx filed name as

ShowCommon.ashx

<%@ WebHandler Language="C#" Class="ShowImage" %>

using System;

using System.Configuration;

using System.Web;

using System.IO;

using System.Data;

using System.Data.SqlClient;

public class ShowImage : IHttpHandler {

public void ProcessRequest(HttpContext context)

{

string empno;

//if (context.Request.QueryString["id"] != null)

// empno = Convert.ToInt32(context.Request.QueryString["id"]);

//else

// throw new ArgumentException("No parameter specified");

empno = context.Request.QueryString["name"];

context.Response.ContentType = "image/jpeg";

Stream strm = ShowEmpImage(empno);

byte[] buffer = new byte[4096];

int byteSeq = strm.Read(buffer, 0, 4096);

while (byteSeq > 0)

{

context.Response.OutputStream.Write(buffer, 0, byteSeq);

byteSeq = strm.Read(buffer, 0, 4096);

}

//context.Response.BinaryWrite(buffer);

}

public Stream ShowEmpImage(string name)

{

string conn = ConfigurationManager.ConnectionStrings["FYPconn"].ConnectionString;

SqlConnection connection = new SqlConnection(conn);

string sql = "Select photo From Food Where name=@name";

SqlCommand cmd = new SqlCommand(sql, connection);

cmd.CommandType = CommandType.Text;

cmd.Parameters.AddWithValue("@name", name);

connection.Open();

object img = cmd.ExecuteScalar();


Project 98

try

{

return new MemoryStream((byte[])img);

}

catch

{

return null;

}

finally

{

connection.Close();

}

}

public bool IsReusable

{

get

{

return false;

}

}

}

After ashx retrieve the image, below is the code needed to display the image in coding

phase.

ImageCommon.ImageUrl = "~/ashxCode/ShowCommon.ashx?name=" + dtrMenu["name"].ToString();


Project 99

4.7 Ajax Techniques Adapting

Few Ajax techniques are used in the member registration at web page.

Below is the code for auto comment on password strength.

<asp:PasswordStrength ID="PasswordStrength1" runat="server" TargetControlID="txtPass"

DisplayPosition="RightSide"

StrengthIndicatorType="Text"

PreferredPasswordLength="10"

PrefixText="Strength:"

TextCssClass="TextIndicator_TextBox1"

MinimumNumericCharacters="0"

MinimumSymbolCharacters="0"

RequiresUpperAndLowerCaseCharacters="false"

TextStrengthDescriptions="Very Poor;Weak;Average;Strong;Excellent"

TextStrengthDescriptionStyles="cssClass1;cssClass2;cssClass3;cssClass4;cssClass5

CalculationWeightings="50;15;15;20"

>

</asp:PasswordStrength>

Below is the code for auto validation.

*Common ASP validator needs to be set and bound to the field before using this Ajax

4.8 Programming Tools

Visual Studio 2010 is used on the development of Cafeteria Management System. .Net

language is the main programming language that will be used in Visual Studio, there

for I chosen this tools for my program development due to .Net language is the major

language I learned in college and also was the language that I most experience with.

4.8.1 Strength of Programming Tools used

Based on my experience, Visual Studio is a very convenience developing software

compare to the other developing software such as Net Bean. Visual Studio had many

features that ease developer in programming such as automate data adapter creation,

auto coding for some components, and auto matching the code wanted to enter. And

visual studio able to support object-oriented programming which make the

programming work become easier.

4.8.2 Weakness of Programming Tools used

When work becoming convenience, developer becoming started to depending on the

tools, and caused developer unable to adapt themselves when using force to using older

version/other programming tools. And based on my experience, web interface

designing by using visual studio is inconvenience, due to the inflexible of alignment

control.

4.8.3 Problem Faced

Overall not much problem is encounter when using .Net language on developing. The

only major problem is occurring when we had error in the database path when using

object-oriented programming. Because the error message point to Problem Domain

Class instead of Data Access Class which lead us to trouble shoot on the wrong area.

And finally the problem is solved after few days of debugging while asking opinion

from senior and classmate.

Software Testing

Cafeteria Management System Chapter 5: Software Testing

Project 102

55..00 SSooffttwwaarree TTeessttiinngg Software testing is the process to evaluate a system whether it reach the expectation

and fulfill the user requirement, and make sure the system is free from any error

before releasing the system to market. Therefore software testing before releasing is

important and necessary in order to provide a high quality and reliable system to

customer.

5.1 Type of Testing

5.1.1 Unit Testing

The idea of unit testing is test the system module by module, which means the

developer will only proceeds to develop the other module when a module is complete,

and ensured it’s free from any error and bug, only proceed to develop the other module.

5.1.2 Integrating Testing

Integrating Testing is the stage where individual modules is combined and test in

group. Which mean the module that’s developed individually are combined and test to

make sure a module wont conflict with the other module and able communicate with

each other. This phase is occurs after unit testing and system testing.

5.1.3 System Testing

System testing is the testing of the entire system, which means all modules, to make the

system is free from any error and bug before releasing to user/customer. In this stage,

the developer should make sure the system is system was fulfilling the user requirement

and able run smoothly without any problem.

5.1.4 User Acceptance Testing

User Acceptance testing is the testing stage where the system will be demo to the user

and receive feedback from them, to make sure the system is meet the user requirement

and expectation. Any feedback from user in this stage will be accept and make

modification to the system according to user response.

Conclusion


Project 116

66..00 CCoonncclluussiioonn This chapter is an overall conclusion for Cafeteria Management System, by conclude

from it strength and weakness, and also discuss about further improvement that could

enhance to the system.

6.1 Link Project to Seminar

My title of my seminar is Ajax, which is an internet technology that able update a

webpage asynchronously. In Cafeteria Management System, Ajax technology is used

in member registration on web page. An auto field validation had been developed by

using Ajax technology, which mean the system will auto validate the require field

without the need of reloading of web page. And function to rate on user entered

password on registration is developed with Ajax too, which will help user to decide

password to user, by telling the password strength directly while user key in.

6.2 Project Achievement

By Overall, the project achieves all the system requirement and objective, all the

module is run as well as in expectation. But that’s a flaw in designing where the

report design for order report doesn’t meet supervisor requirement, where the report

information should include the order information such as meal price, meal name and

etc. The information failed to carry due to the failure from displaying information

from 4 different database tables.

6.3 Project Management Issues

The difficulty on this system developing is programming some function that never

being done before, such as uploading image by using vb.net. When come to coding a

function that never done before, lot of effort and time need to be investing on the

researching. Some other difficult part is figuring the code logic on how to achieve the

function wanted, such as transmitting of huge information from Database Access

Class to Problem Domain Class. And the other issues occurring are combining

module with the other teammate, which may cause system conflict due asynchronous

of information code.


Project 117

6.4 Evaluate Project Strengths and Weaknesses

6.4.1 Strengths

Error Reduction

By changing from the old processing method, which is record everything manually

by pen and paper, to automate management system, it could reduce the error might

happened by using manual recording. Human get tired and confuse when working

for a wrong period and will cause error, but a system wouldn’t useless bug happen

or human mistake when key in information.

Easy Maintenance

When every record is keep by using paper work, mean it require a lot space to store

the record. And it would take long time retrieve information from bunch of paper

work, and it’s time and man power consuming on maintenance. But automate

management system could finish all the maintenance easily.

Efficiency Improvement

Efficiency of cafeteria could be improve, which mean improve in term of services as

well, by using simple and fast response computer to replace human work.

Security

Only authorized user are able to login into the system, therefore could protect all the

information from disclose. It’s more secure compare to paper work recording, people

are able to read information in paper recording as long as able to contact physically

with the record, but system need authorization account.

Convenience

With the existing of web site, users are able to view all the meal offered by the cafeteria,

and also able to make reservation via internet. And the seat admission module help

cafeteria to keep track on every table status in the shop, it ease the staff to assign table

to customer to rush hour.


Project 118

6.4.2 Weakness

Web Page Interface

The design of web page interface is not so satisfied. Some of the page alignment is over

border which is not necessary.

Starting Speed on Table Admission Form

This form takes more time to start up compare to other form, approximate 2-3 second to

start up because it load more information on starting compare to the other form.

6.5 Suggestion for future improvement

Advance Ajax techniques could be enhanced into the webpage, to improve the

efficiency of the web page. For example, while user viewing promotion and meal

menu at the webpage, it could use Ajax technology to load the selected item image

and information, while the current design is using traditional web method. And the

user interface on webpage could be further improved as well.

6.6 Personal Reflection

I learn a lot upon completing this final year project. It’s the 1st assignment that I need

to start from project specification, designing until documentation, which all the

previous are not necessary. It somehow giving me an image on how software is

develops from beginning to the end in the real market. And by debugging some bug

that I had never encountered before is also increasing my programming experience

and self value on programming market.

And by completing this project, I had learned some programming knowledge that

could not obtain from school, such as Image uploading, the use of Ajax technology

and so on. And while facing problem, I had obtain some help from senior which

working in the real programming market. They had provided me some valuable

opinion, and although some of the conversation is not related or help the project, but

their conversation had help me to explore more on IT field by understanding what a

language or technique could really do. For example from their conversation, I

understand that advanced SQL statement could actually execute some function that

need to be complete by using programming language in my level.
