PREFACE

In the modern world of the computer , Internet and the increasing popularity of

Internet , more and more peoples are getting use to of Internet, due to which

Internet Cafes are being opened as a full time business .

Internet Cafe is a place where a person can surf Internet , can do video or voice

chatting , can watch movies ,can download data etc.

Generally to keep track of costumers sitting on which system is done through

making entries in a register(notebook).

But this can done via a click of mouse as well.

What Cafe mgt. System do is it allows the host to keep track of costumers sitting

on which system by just a click of mouse. Once the surfing session of a customer

is over the customer name , address , phone numbers gets stored in the

database with date and time.

Thus the work and time is saved as the database can be updated regularly at the

back-end , and tedious job of doing entries in a register can be avoided.

Chapter 1:- INTRODUCTION

ABOUT US:

Cafe Management System has a simple mission.

To make the management of cafe easy , faster , reliable.

We make it easy.

Cafe Management System do following tasks:

1. Keeps track of costumers sitting on which computer.

2. Then makes a entry in to the database i.e. costumer name , phone no. and

address with signing in time and signing out time with date is stored into thedatabase.

The road ahead.

We aim to make this project more user friendly , faster and reliable.

We are aiming to embed Screen locker into the software to make it more and

more secure.

We are proud of our achievements and excited about the future. However, somethings that will not change are our commitment to our project and belief in

endless possibilities.

About JAVA:

Java is an object oriented language, multithreaded programming language developed by Sun

Microsystems in 1991.it is designed to be small, simple and portable across different

platforms as well as operating systems.

The popularity of Java is due to its unique technology that is designed on the basis of three

key elements. They are the usage of applets, powerful programming language constructs and

a rich set of significant object classes.

When a program is compiled, it is translated into machine code or processor instructions that

is specific to the processor. In the Java development environment there are two parts: a Java

compiler and a Java interpreter. The compiler generates the byte code(a set of instructions

that resemble machine code but are not specific to any processor)instead of machine code and

the interpreter executes the Java program.

The disadvantage of using bytecode is the execution speed. Since system specific programs

run directly on the hardware, they are faster than the Java bytecodes that is processed by the

interpreter. In order to write a Java program, an editor, a Java compiler and a Java Runtime

Environment are needed.

The editor can be a Notepad, Wordpad, MS-DOS editor etc. the easiest way to get a Java

Compiler and Runtime Environment is to download Suns Java Development Kit. This

provides system input and output capabilities and other utility functions in addition to classes

that support networking, common Internet protocols and user interface toolkit functions.

FEATURES OF JAVA

SIMPLE OBJECT-ORIENTED ROBUST MULTITHREADED ARCHITECTURE-NEUTRAL DISTRIBUTED DYNAMIC OBJECT-ORIENTED PROGRAMMING APPROACH


8/84

Another way to access database(JDBC-ODBC)

SYSTEM ARCHITECTURE

A well-defined software application is partitioned into separate logical parts called layers.

Each layer has different responsibilities in the over all architecture. These layers are purely

abstraction and do not corresponds to physical distribution.

Typical layers in a software system are as follows:-

1) Presentation layer:- In this layer are parts that handle the user interface and userinteraction.

2) Business l0gic layer:- This layer contains components that handle the programminglogic of the application.

3) Data layer:- This layer is used by the business logic layer to persist state permanently.This state normally consists of one or more databases where data is stored.


9/84

THE TWO-TIER ARCHITECTURE

It is a simple client server application in which the processing workload falls onto the client

computers shoulders and the server simply act as a traffic controller between the client and

the data.

The term fat client for this type of architecture is due to the bulk of the processing

requirements at the client side. In this architecture , the presentation layer and the business

logic layer are hosted in one tier and data layer is on other tier.

BENEFITS OF EBJ:

Performancethe performance of EJB is superior to CGI because there is no processcreation for each client request. Instead, each request is handed by the EJB 3.0

container process. After EJB 3.0 is finished processing a request, it stays resident in

memory, waiting for another request.

Portabilityyou can move them to other operating systems without serious hassles. Rapid development cycleAs a java technology, EJB 3.0 have access to the rich

java library, which helps speed up the development process.

RobustnessEJB 3.0 are managed by JVM. As such, you dont need to worry aboutmemory leak or garbage collection.

Widespread acceptanceJava is a widely accepted technology.

Chapter 2:- SYSTEM ANALYSIS

This process consists of the following stages:

Research & Analysis

This is the first stage where in the designers have to analyze the field so as to understand the

requirement of the user(s). This is accomplished through several interactive sessions between

the user(s) and the designer, where by the designer tries to understand the working of the

system with all the different factors that influence the database. Designers can then make the

package only after they have understood the functionality of the system.

Normalization

Normalization is a process that takes the relational schema through a series of tests to certify

whether or not it belongs to a certain normal form. It also aims at refining the data structureto minimize data redundancy and to avoid update anomalies in the database.

First Normal Form (1NF)

A Relation in which repeating groups are eliminated i.e. all the attributes in the

relation must be single valued or atomic in nature.Second Normal Form (2NF)

A Relation in which every non-prime attribute is fully, functionally dependent on the

complete prime attribute and not only a part of the prime attribute. The prime attribute

uniquely identifies the non-prime attribute.

Third Normal Form (3NF)

A Relation is 3NF if and only if it is in 2NF and every non-prime attribute is transitively

dependent on the prime attribute.

Building Stage

At this stage, we take the database design and implement it. Using the tools provided by the

MSaccess tables and Data Reports does the implementation.

Production Stage

At this stage, the database commences its role as a repository of data. The user can log

in through the front end.


12/84

SYSTEM DESIGN:

Software Navigation

Software Navigation gives details of how the back-end (tables), in a database is connected to

its front-end (actual display forms). This in essence explains how the data gets stored in thedatabase and how it is retrieved after some user input is given.

Clearly, this operation takes place only through the implementation of certain software for the

front-end and back-end of the database.

Back-End: MS-Access , EJB 3.0 and web logic 10.0 server

Front-End: JAVA and JAVA SWINGS

The connectivity between the back-end and the front-end can be established by any of the

following standards:

ADODC: Active Data Object Data Control ADODB: Active Data Object Database Data Environment ADO: Active X Data Objects/Control RDO: Remote Data Object RDODC: Remote Data Object Data Control

The connectivity in this project has been established using Active X Control. Active X hasbeen implemented through the use of ADODB.

ADO is the method of data access that Microsoft has introduced. ADO provides a means by

which your program code accesses the database.

The ADO connects to the database to OLE DB Provider. The OLE DB Provider exposes

databases to ADO, which in turn allows you to connect to the data.

A data control is a custom control that handles communication with the database. You

simply set a few properties and bind some other controls to the data control to display

information.

Chapter 3:- SOFTWARE REQUIREMENTS AND SPECIFICATION

Introduction

Purpose:

The purpose of this document is to describe the requirements for implementing and using the

Cafe Management System.

Scope:

The document is meant to be used by the developers to guide them through the development

and for the users to verify their requirements.

Overview:

The developers are responsible for the development of the database system for themaintenance, updating and to provide required information to the user so that he can use the

product effectively.

General Description

Product Prospective:

The product is independent of the other products and only dependent on DBMS to provide all

the functionality.

Product Functions:

The system has to make available all the details regarding the different trains and their

availability status, routes, fares, etc..

External Interface Requirements

User Interface Interface is neatly and consistently designed. Meaningful push buttons and menus are to be provided for easy usage. Help should be provided wherever necessary. Easy navigation facility between forms is necessary. Appropriate messages are to be displayed in case of errors or exceptions.


14/84

System Requirements

1) Hardware Requirements:The editor is optimized to run on any hardware configuration. All it needs is

A system with color monitor. PENTIUM IV Processor. Minimum Ram of 128.0 MB2) Software Requirements

The editor can be installed and run in any system, which provides

PLATFORM Windows XP and above. BACKEND MS-Access , Weblogic server 10.0 FRONT END JAVA.

Acceptance Criteria

The developer will need to demonstrate the effective working of the system with sample data.

Queries and updates to the database should be supported in a consistent way. Check validity

of inputs by the user and give appropriate messages when necessary. The following features

must be satisfied.

No two Users can have the same account. No two Companies can view other companys messages. Critical data like password and other credentials cannot be left blank.

The system should support easy and consistent way for populating and removing data from

the database and for showing the output accordingly.


15/84

Preliminary assessment

First phase of any project is preliminary assessment. The base of this phase is recognition

of needs for improving an information system or a procedure. This need leads to an initial

investigation to determine whether an alternative system can solve the problem.

The primary goal of the project is to enable the booking, cancellation of tickets and

providing information. A user need to be registered through their login ids and password.

When the user enters the data into the system either of the options in the menu list as a query.

The output/result will be given as specified.

Feasibility study

Feasibility study is a test of a system proposal according to its workability, impact onorganization, ability to met user needs and effective use of resources.

Task of this phase should clearly define:

Users demonstrable needs. Availability of resources. Estimate the resources required. Impact of this system on the organization Define & document in outline a proposed system.

There are some types of feasibility:

Technical feasibility: It is related to the availability of hardware and software toperform the essential computing.

Economic return feasibility: The new system should be economically beneficial. Forthe cost/ benefit analysis is performed.

Non economic return feasibility: System can be justified based on benefits inmonitory terms.

Time feasibility: System should be implemented within mentioned time constraints. Legal & ethical feasibility: System should exist within legal & ethical boundaries.

Analysis

Analysis is a detailed study of various operations performed by a system and their

relationships within & outside the system.


16/84

Design

System design is determination of processes & data that are required by a new system.

Design describes a final system & process by which it is developed. It refers to the technical

specifications that will be applied in implementing the system.

Implementation & testing

Implementation is the acquisition and integration of the physical and conceptual resources

that produce a working system. It is concerned with those tasks leading immediately to a fully

operational system. It involves programmers, users and operational management but its plan

of timing is a prime function of system analysis.

Maintenance

Periodic maintenance of hardware & software are required to keep in tune with design

specifications. If the new information is inconsistent with the design specification, then

change have to be made.

Review & evaluation

A review is conducted whether system objectives are being met with the user requirements

and what are the problems in smooth running. Steps are taken to resolve them.
