The main aim of the project is to provide service smart security to the customers. This system provides good and efficient information and thus making the service smarter. It is an interface for customers to browse the catalogue and order the food online. Using the power of Internet multiple interest parties can order with complete security and control.

ESC system maintains and processes all sort of information pertaining to the order type options control the life cycle of an order. It provides an end to end solution to sell and manage.

By following this new approach the information can be accessed from anywhere just with a mouse click. This helps the users by saving lot of time and providing the user with up to date information.

Goals For The System: By following the new approach the information can be accessed from any where

just with a mouse click. This helps the user by saving lot of time.

The developed package should be able to create a good interface between user

and database.

It should guide the user if it all any invalid entries are made and provide feedback

to the users.

It should sustain reasonable amount of network traffic and provide the user with

the required information with out any delay.

The Goals Achieved By This Project: This project provides a very good user interface for the user to access information

with least effort.

The system provides various functionalities to the user for any type of details

about the store.

Since the information is available on the server at any point of time from the store

updated information is provided.

1.1 Existing System:

In this very busy world and when the technology is being used efficiently to conserve the time we cannot afford to spend so much of time. To overcome the disadvantage of the existing system that will provide the automate information on a system which people can access from this system, which obviously provides proper information with minimum time consumption. Thus this new system provides the user an easier and a better way of accessing the information.

1.2 Proposed System:

With the proposed E-commerce Shopping Cart (ESC) system Maintaining and Processing all sort of information pertaining to Order Type options controls the lifecycle of an order. The Order Type design tool allows you to define an unlimited number of order types, each with unique sequence.

1.3System Overview:

E-Commerce Shopping Cart (ESC) software designed for the customer to order

the food through online. Using the power of the Internet to open your order management application to multiple interest parties, with complete security and control.

1. The Browse Phase: This module will allow the customer to browse through the store before login. The main page will show the name and other contextual information regarding the online store and when the customers selects the ordering option in the front page of the ordering system it shows the criteria of displaying the products.

2. Registration Phase:

In the register phase of the application, customer will be allowed to input their postcode to validate weather the store delivers the order to the postcode. If the validation returns true and the order can be delivered to the customer address. The customer is required to fill a registration from including all the necessary details that are required to fulfill the order dispatch.

3. Login:

The customer will be allowed to login at the beginning of the shopping or at of the shopping providing their email address as username and password. If the customer logins in the beginning, the customer is given the choice of ordering the same as the last time with complete view of the shopping and also to edit if required by the customer to create new order. Adding additional items to take the union of the customers previous order products and show after the login.

4. View Items:

The customer can at any point of time be able to view his/her shopped products that are added to the basket and at the same time also able to update and delete and individual and group products from the shopping list. There will be an option for the customer to increase (+) and decrease (-) the quantity of an individual product in the shopping basket.

5. Add_To_Cart: The application will allow the customer to add individual products or group of products from the shopping cart, and will automatically update the totals and others.6. Remove_ From _Cart:

REQUIREMENT ANALYSIS

Software Requirements Specification 3.1 Introduction3.1.1 PurposeThis SRS describes the software functional requirements for E-COMMERCE SHOPPING CART (ESC). This software is intended to be used by the storeowner that will implement and verify the correct functioning of the system. By adopting this process the customers can order food online and also allow them to pay for the order with their credit/debit card.3.1.2 Project Scope and Product Features The ESC will provide an interface for customers to browse the catalogue before or after login. Here the customer is allowed to view his/her shopped products that are added to the basket .The customer can also update and delete and individual and group products from the shopping list. Here the customer is given an option to increase and decrease the quantity of individual products in the shopping basket. The application even allows the customer to remove selected items from the shopping cart, and will automatically update the totals and others. The application will allow the customer to carry on shopping with the click button. In the register phase of the application, customer will be allowed to input their post code to validate whether the shop/store delivers the order to that post code. If the validation returns true and the order can be delivered to the customer address. The customer is required to fill a registration form including all the necessary details that are required to fulfill the order dispatch. The customers can order food from the on-line store to be delivered to specified area through which the time of the customer is been saved. The main idea behind this software is that the customer can get his food faster.

3.1.3 References1. Cafeteria Ordering System Vision and Scope Document.3.2 Overall Description3.2.1 Product PerspectiveThe ESC is a new system that replaces the age old manual and telephone ordering process and picking up food.

SYSTEM DESIGN]SCOPE OF THE DOCUMENT

The Software Design Document (SDD) is a comprehensive software design model consisting of four distinct but interrelated activities: data design, architectural design, interface design, and procedural design.

The Data design describes structures that reside within the software. Attributes and relationships between data objects dictate the choice of data structures.

The Architecture Design uses information flow characteristics, and maps them into the program structure. Transformation mapping method is applied to exhibit distinct boundaries between incoming and outgoing data. The Data Flow diagrams allocate control input, processing, and output along three separate modules.

The Interface Design describes internal and external program interfaces as well as the design of human interface. Internal and external interface designs are based on the information obtained from the analysis model.

The Procedural Design describes structured programming concepts using graphical, tabular, and textual notations. These design mediums enable the designer to represent procedural detail that facilitates translation to code. This blueprint for implementation forms the basis for all subsequent software engineering work.

The SDD contains the following documents:

Architecture Design Data Design

Interface Design

Procedural Design

4.1 Architecture Design:

The architectural design of a software project is simply the design of the entire software system. This includes the hierarchy of the modules and also which modules are present in the systemData-flow Diagram (DFD)

Data flow diagrams are directed graphs in which the nodes specify processing activities and the arcs specify data items transmitted between processing nodes. A data flow diagram might represent data flow between sequential routines, data flow concurrent process, or data flow in a distributed computing system, where each node represents a geographically remote processing unit.

Unlike flow charts, data flow diagrams do not indicate decision logic or condition under which various nodes in the diagram might be activated. Data flow diagrams can be expressed using special symbols. These symbols can be used to denote processing nodes, data nodes, data sources and data stores.

Data Store: Holds data

Process: Transforms or moves

Source /sink: original or final destination of data

Data Flow: Indicates the direction of movement of Data

SHAPE \* MERGEFORMAT

4.2 Data Design:The data design specifies how the data of the program is going to be stored. This includes all major data structures and methods. For each data structure, the actions that can be performed on it are specified.

5.2 SYSTEM TESTING The philosophy behind testing is to find errors. Test cases are devised with us in mind .A strategy employed for system testing is code testing.5.2.1 Code Testing:

This strategy examines the logic of program. To follow this method our project supervisor developed some test data that resulted in executing every instruction in the program and module i.e. every path is tested. Systems are not designed as entire nor are they tested as single systems. To ensure that the coding is perfect two types of testing is performed.5.2.2 TYPES OF TESTING:

Unit Testing.

Link Testing.

Integration testing

Unit Testing:

In this application developer tests the programs up as system. Software units in a system are the modules and routines that are assembled and integrated to form a specific function. Unit testing first done on modules, independent of one another to locate errors. This enables to detect errors. Through this error resulting from interaction between modules initially avoided.

Link Testing:

Link testing does not test software but rather the integration of each module. The programmer tests where modules are designed with different parameters, length, type etc.

Integration testing:

All the tested modules are combined into sub system, which are then tested. The goal is to see if the modules are properly integrated, and emphasis being on the testing interfaces between the modules.5.2.3 TESTING METHODS: Testing is a process of executing a program to find out errors. If testing is conducted successfully, it will uncover all the errors in the software. Any testing can be done in two ways:

BLACK BOX TESTING:

It is a test case method used on functional requirements of the software .it will help a software engineer to derive sets of input conditions that will exercise all the functional requirements of the program .Black Box testing attempts to find errors in the following categories: Incorrect or missing functions.

Interface errors.

Errors in data structures.

Performance errors.

Initialization and termination errors.

WHITE BOX TESTING: It is a test case design method that uses the control structures of the procedural design to derive test cases. Using test cases this testing software Engineer can derive the following test cases:

Exercise all the logical decision on either true or false sides.

Executing all loops at their boundaries and within their operational boundaries.

Executing the internal data structures to assure their validity.

5.2.4 SYSTEM SECURITY:

Checks and controls

Physical security:

Physical security is maintained by having the back up of all the data that is needed for the project to run.

5.2.5 Os security: The platform that we are using is Win NT which is protected made kernel and this give the programming to run on its own protected made which makes project to be handled on its won resources and which also works as the client in many cases.

5.2.6 Application level security

Application maintains the security by handling clients request properly which makes it to be very efficient at critical time .The project makes to be very reliable at crash times thus not distributing the other process on the system .This makes the application to have efficient security concerns.OUTPUT SCREENS

SYSTEM TOOLS 7.1 FEATURES OF LANGUAGE USED

Java Database connectivity

What is JDBC?

JDBC is a Java API for executing SQL .it consists of a set of classes and interfaces written in the Java programming language. JDBC provides a standard API for tool/database developers and makes it possible to write database applications using a pure Java API.

USING jdbc, it is easy to send SQL statements to virtually any relational database. One can write a single program using the JDBC API, and the program will be able to send SQL statements to the appropriate data base. The combination of java and JDBC lets a programmer write it once and run it anywhere.What does JDBC do?

JDBC makes it possible to do three things:

Establish a connection with a database.

Send SQL statements.

Process the results.

JDBC verses ODBC and other APIs

At this point, Microsofts ODBC (Open Database Connectivity) API is that probably the most widely used programming interface for accessing relational databases.It offers the ability to connect to almost all databases on almost all platforms. So why not just use ODBC from Java? The answer is that you can use ODBC from Java. But this is best done with the help of JDBC in the form of JDBC-ODBC Bridge, which we will

cover shortly. The question now becomes why do you need JDBC?There are several answers to this question:

1. ODBC is not appropriate for direct for direct use from Java because it uses a C interface. Calls from Java to native C code have a number of drawbacks in the security implementation, robustness, and automatic portability of applications.

2. A literal translation ODBC C API in to java API would not be desirable for

example, java has no pointers and ODBC makes copious use of them, including

the notoriously error prone generic pointer void*. You can think of JDBC as

ODBC translated in object-oriented interface that is natural for java program.

3 DBC is hard to learn. It mixes simple and advanced features together, and it has

complex options even for simple queries. JDBC, on the other hand, was designed

to keep simple things simple while allowing more advanced capabilities where

required

4. A Java API like JDBC is needed in order to enable a pure java solution. When

ODBC is used, the ODBC driver manger and drive must be manually installed

on every client machine. When the JDBC driver is written in java, however,

JDBC code is automatically installable, portable and secure on all java

platforms from network computers to mainframes

JDBC driver types

The JDBC drivers that we are aware are of at this time fit in to one of the four

categories

JDBC-ODBC Bridge plus ODBC driver

Native-Api partly-java driver

JDBC Net pure java drive

Native-protocol pure java driver

JDBC-ODBC Bridge

If possible, use a pure Java JDBC driver instead of the Bridge and an ODBC driver. This completely eliminates the client configuration required by ODBC. It also eliminates the potential that the java VM could be corrupted by an error in the native code brought in by the Bridge (that is, the Bridge native library, the ODBC driver manager library, the ODBC driver library, and the data base client library

What is the JDBC-ODBC Bridge?

The JDBC ODBC Bridge is a Jdbc driver, which implements JDBC operations by translating them in to ODBC operations. To ODBC it appears as a normal application program, the Bridge implements JDBC for any data base for which an ODBC driver is available the bridge is implemented as the Sun.jdbc.odbc java package and contains a native library used to access ODBC. The Bridge is a joint development of intervolve and java soft.

JAVA SERVER PAGES (JSP)

Java server pages are a simple, yet powerful technology for creating and maintaining dynamic-content web pages. Based on the Java programming language, Java server pages offers proven portability, open standards, and a mature re-usable component model. The Java server pages architecture enables the separation of content generation from content presentation. This separation not ease maintenance headaches, it also allows web team members to focus on their areas of expertise .Now, web page designer can concentrate on layout, and web application designers on programming, with minimal concern about impacting each others work.

Features of JSP:

Portability:

Java server pages files can be run on any web server or web-enabled application server that provides support for them. Dubbed the JSP engine, this support involves recognition, translation, and management of the Java Server Pages life cycle and its components.Components:

It was mentioned earlier that the Java Server Pages architecture can include reusable Java components. The components currently supported include Servlets.

Processing:

A Java Server Pages file is essentially an HTML document with JSP scripting or tags. The Java Server Pages file has a JSP extension to the Server as a Java Server Pages file.

Before the page is served, the Java Server Pages syntax is parsed and processed into a Servlet on the server side .The Servlet that is generated outputs real content in straight HTML for responding to the client.

Steps in the execution of a JSP Application:

1. The client sends a request to the web server for a JSP file by giving the name of the JSP file within the form tag of a HTML page.

2. This request is transferred to the JavaWebServer .At the server side JavaWebServer receives the request to the JSP engine.

3. JSPengine is program, which can understand the tags of the JSP, and then it converts those tags into a Servlet program and it is stored at the server side. This Servlet is loaded in the memory and the result is given back to the JavaWebServer and then it is transferred back to the result is given back to the JavaWebserver and then it is transferred back to the client.

JDBC connectivity

The JDBC provides data base- independent connectivity between the J2EE platform and wide range of wide range of tabular data source. JDBC technology allows an application component provider to:

Perform connection and authentication to database server Manager transactions. Move SQL statements to data base engine for preprocessing and execution

Execute stored procedures.

Inspect and modify the results from the select statements.FEATURES OF ORACLE

Some of the features of oracle supported for the project are as follows:

Large Database Managements System

Oracle supports large databases potentially tear bites in size

Many Concurrent data base users Oracle supports large numbers of concurrent users executing a variety of database applications operating on same data .It minimizes data contention and guarantees data concurrency.

High transaction processing performance

Oracle maintains the preceding features with a high degree of overall system performance. Database users do not suffer from slow processing performance.,Security

By providing proper authentication oracle provides security to the database users.

ROLE OF ORACLE IN DATABASE:

ORACLE9i is one of the many database services that plug into a client/server model. It works efficiently to manage resources, a database information, among the multiple clients requesting & sending.

STRUCTURED QUERY LANGUAGE (SQL):

SQL is an inter-active language used to query the database and access data in databases has the following features:

1. It is a unified language.

2. It is a common language for relational database.

3. It is a non-procedural language.

CONCLUSION

Conclusion The theme of the project is to provide service smart, security to the customer. This site provides a good and efficient way of ordering food through online which saves the time of the customer.

This system provides good and efficient information and thus making the service smarter. It is an interface for customers to browse the catalogue and order the food online. ESC makes customer service easier as required by the customer. ESC system maintains and processes all sort of information pertaining to the order type options control the life cycle of an order. By following this new approach the information can be accessed from anywhere just with a mouse click. This helps the users by saving lot of time and providing the user with up to date information. The Internet also provides an inexpensive and secured method for capturing orders electronically and easily integrated with the customers.

This site also provides a feedback form such that any customer can give comments to the storeowner.Scope for Future Work:

Powerful search capabilities enable user to instantly pinpoint any product, using the hierarchy or product description.

To produce printed catalogue

Any other feature that client needs. BIBILIOGRAPHY BIBILIOGRAPHY Software Engineering by Roger s. pressman, 4th Edition
