1.1. Project Description - ONLINE SHOPPING WEBSITE PROJECT
E-commerce is fast gaining ground as an accepted and used business paradigm. More and more business houses are implementing web sites providing functionality for performing commercial transactions over the web. It is reasonable to say that online shopping system project report the process of shopping on the web is becoming commonplace.The objective of this online shopping system project project is to develop a general purpose e-commerce store where any product (such as books, CDs, computers, mobile phones, electronic items, and home appliances) can be bought from the comfort of home through the Internet.
However, for implementation purposes, this online shopping system project paper will deal with an online book store.
An online store is a virtual store on the Internet where customers can browse the catalog and select products of interest. The selected items may be collected in a shopping cart. At checkout time, the items in the shopping cart will be presented as an order. At that online shopping system project report time, more information will be needed to complete the transaction. Usually, the customer will be asked to fill or select a billing address, a shipping address, a shipping option, and payment information such as credit card number. An e- mail notification is sent to the customer as soon as the order is placed.
1.2. Technologies Used - ONLINE SHOPPING WEBSITE PROJECT IN JAVA
1.2.1. Java Server Pages (JSP)
With the advent of Internet, the monolithic application architecture changed to the multi-tiered client/server architecture. The need for server-side scripting gradually began to dominate aspects of Web Programming. Microsoft introduced Active Server Pages (ASP) to capture the market demand for server-side scripting. Working on similar lines, Sun Microsystems released Java Server Pages (JSP) to add server side programming functionalities to Java.
A typical web application consists of the presentation logic representing the static content used to design the structure of a web page in terms of the page layout, color, and text. The business logic or the dynamic content involves application of business intelligence and diagnostics in terms of financial and business calculations. When developing web applications, time is often lost in situations where the developer is required to code for the static content.
JSP Technology has facilitated the segregation of work profiles of a web designer and a web developer. A Web Designer can design and formulate the layout for the web page by using HTML. On the other hand, a Web Developer working independently can use Java code and other JSP specific tags to code for the business logic. The simultaneous construction of static and dynamic content facilitates development of quality applications with increased productivity.
The JSP Request-Response Cycle:
JSP files are stored on the web server with an extension of .jsp. When the client/browser requests for a particular JSP page, the server in turn sends a request to the JSP Engine.
The following figure represents the process of the flow of events that online shopping system project report occur after a client requests for a JSP page.
The request-response cycle essentially comprises of two phases, namely the translation phase and request-processing phase. The translation phase is implemented by the JSP engine and involves generation of a servlet. Internally, these results in the creation of a class file for the JSP page that online shopping system project report implements the servlet interface. During the request-processing phase, the response is generated according to the request specification. The servlet then sends back a response corresponding to the request received. After the servlet is loaded for the first time, it remains active and possesses all the subsequent requests with responses, saving time that online shopping system project report would otherwise be lost in reloading a servlet at each request.
1.2.2 JDBC
JDBC (Java Database Connectivity) is an application program interface (API) specification for connecting programs written in Java to the data in popular database. It is provided by Sun Microsystems, the application program interface lets you encode access request statements in structured query language (SQL) that online shopping system project report are then passed to the program that online shopping system project report manages the database. It returns the results through a similar interface. From the user’s point of view, Java application looks something like this online shopping system project:
Features of JDBC API:
Java Database Connectivity (JDBC) provides a database programming API for Java programs. Some of the features of JDBC API are as follows:
Contains a set of classes and interfaces that online shopping system project report are used to connect to a database built using any DBMS/RDBMS, submit SQL queries to a database, and retrieve and process the results of SQL queries.
Is a low-level interface in which SQL select and update statements are called directly from within Java programs.
Can be used with both two-tier and three-tier database architectures. In two-tier architecture, a Java program invokes the methods of JDBC API, which in turn communicates with the database server. In three-tier architecture, a Java applet or an HTML form submits SQL queries to a middle-tier server. Middle-tier server in turn uses JDBC API to communicate with the database server.
JDBC Architecture:
The JDBC architecture is based on a collection of Java interfaces and classes that online shopping system project report together enables you to connect to data sourced, to create and execute SQL statements, and to retrieve and modify sata in a database. These operations are illustrated in the figure below:

JDBC Architecture:
The JDBC architecture is based on a collection of Java interfaces and classes that online shopping system project report together enables you to connect to data sourced, to create and execute SQL statements, and to retrieve and modify sata in a database. These operations are illustrated in the figure below:
š JDBC-ODBC Bridge Driver: The first category of JDBC drivers provides a bridge between the JDBC API and the ODBC API. There are several DBMS/RDBMS, such as MS Access and SQL Server that online shopping system project report contain the ODBC Driver embedded into them. Since the ODBC API is written in the C language and makes use of pointers and other constructs that online shopping system project report Java does not support, a Java program cannot directly communicate with an ODBC Driver. The bridge translates the standard JDBC calls to corresponding ODBC calls, and sends them to ODBC data source via ODBC libraries.
š Native API Partly Java Driver: These drivers use a mixture of Java implementation and vendor specific native APIs to provide data access. JDBC database calls are translated into vendor specific API calls. The database will process the request and sends the result back through the API, which will in turn forward them back to the JDBC driver. The JDBC driver will translate the result to the JDBC standard and return them to the Java application. There is one layer fewer to go through than for a type 1 driver and so in general a type 2 driver will be faster than a type 1 driver.
Some DBMS/RDBMS such as DB2 and Informix contain a JDBC driver supplied by the database vendor.
š Intermediate Database Access Server: Type 3 drivers use an intermediate database server that online shopping system project report has the ability to connect multiple Java clients to multiple database servers. Clients connect to database server via an intermediate server component that online shopping system project report acts as a gateway for multiple database servers. The java client application sends a JDBC call through a JDBC driver to the intermediate data access server, which completes the request to the data sourcing using another driver ( for example, a type 2 driver).
BEA WebLogic includes a type 3 driver. One of the benefit of using a type 3 driver is that online shopping system project report it allows flexibility on the architecture of the application, as the intermediate server can can abstract details of connection to database servers.
š Native Protocol Pure Java Driver/JDBC-Net Pure Java Driver: These drivers convert the JDBC API calls to direct network calls using vendor specific networking protocol. They do this online shopping system project by making direct socket connections with the database. Type 4 drivers offer better performance than others.
1.2.3. Hyper Text Markup Language (HTML)
Hypertext Markup Language (HTML) is a language for describing how pages of text, graphics, and other Information are organized, formatted, and linked together. It is not really a programming language in the sense of COBOL or Visual Basic, but it does provide powerful capabilities for text formatting and output display. The original purpose of HTML was primarily as a tool for making text documents readily available on the Internet. Basic graphic support was added, and the things started to take off. Now we have sound, live video, retail catalogs, and much, much more available to us.
HTML pages are the standard interface to the Internet. This online shopping system project basic language provides the necessary nuts and bolts for building Web pages.
HTML stands for Hyper Text Markup Language and was developed specifically for use on the system of links, which can be non sequential in order. HTML is not a programming language. It is a marking up language used for linking one piece of information to another.
Using a markup language means that online shopping system project report tags can be added to the words in the document and web enable them. A tag is a set of descriptive formatting codes used in HTML document that online shopping system project report instructs a web browser how to display text and graphics on a web page.
HTML 2.0 is the first standard of HTML specification, released in 1996. HTML 3.6 was the next specification to be developed. It was a joint effort of many software companies like Microsoft, IBM, Sun Microsystems, Novell and others.
HTML 4.0 is the latest version of HTML, which includes CSS and dynamic HTML features.
1.2.4. JavaScript
The project uses JavaScript as the client side scripting language for JSP/HTML pages in the project.
JavaScript is an easy to use object-scripting language designed for creating live online applications that online shopping system project report link together resources on both clients and servers. JavaScript is designed for use by HTML page authors and enterprise application developers to dynamically script the behavior of objects running on either the client or the servers. JavaScript ‘s design and concept represent the next generation of software for the Internet and is:
š Designed for creating network centric applications
š Complementary to and integrated with Java
š Complementary to and integrated with HTML
š Open and cross platform
JavaScript is a platform-independent, event driven, interpreted programming language developed by Netscape Communications Corp. and Sun Microsystems. Originally called Livescript, JavaScript is a programming language that online shopping system project report can be included on web pages to make them more interactive.
JavaScript is easier to understand, less complex version of its distant cousin, Java. It is a text-based language that online shopping system project report must be placed within HTML that online shopping system project report must be placed within, HTML, to be read by the browser and interpreted so the instructions can be performed.
JavaScript is a preferred language for client side scripting. This online shopping system project is mainly because when client side scripting is done browser compatibility is an issue of concern and both major browsers support JavaScript.

SQL PLUS: ONLINE SHOPPING WEBSITE PROJECT
SQLPLUS is usually thought of as a kind of interactive report writer. It uses SQL to get information from the Oracle database, and lets you create reports by giving you easy control over titles, column headings, subtotals and totals, reformatting of numbers and text, and much more. It also can be used to change the database by using insert, update, and delete commands in SQL. SQLPLUS can even be used as a code generator, where a series of commands in SQLPLUS can dynamically build a program and then execute it.
In most production applications, more advanced report writers are used—such as Web-based parameter-driven reports. SQLPLUS is most commonly used for simple queries and printed reports. Getting SQLPLUS to format information in reports according to your taste and needs requires only a handful of commands, or keywords that online shopping system project report instruct SQLPLUS how to behave.
You can write SQLPLUS reports while working interactively with SQLPLUS—that online shopping system project report is, you can type commands about page headings, column titles, formatting, breaks, totals, and so on, and then execute a SQL query, and SQLPLUS will immediately produce the report formatted to your specifications. For quick answers to simple questions that online shopping system project report aren’t likely to recur, this online shopping system project is a fine approach. More common, however, are complex reports that online shopping system project report need to be produced periodically, and that online shopping system project report you’ll want to print rather than just view on the screen. Unfortunately, when you quit SQLPLUS, it promptly forgets every instruction you’ve given it. If you were restricted to using
SQLPLUS only in this online shopping system project interactive way, then running the same report at a later time would require typing everything all over again.
The alternative is very straightforward. You simply type the commands, line by line, into a file. SQLPLUS can then read this online shopping system project file as if it were a script, and execute your commands just as if you were typing them. In effect, you create a report program, but you do it without a programmer or a compiler. You create this online shopping system project file using any of the popular editor programs available or even (given certain restrictions) a word processor.
The editor is not a part of Oracle. Editors come in hundreds of varieties, and every company or person seems to have a favorite. Oracle realized this online shopping system project, and decided to let you choose which editor program to use, rather than packaging a program with Oracle and forcing you to use it. When you’re ready to use your editor program, you suspend SQLPLUS, jump over to the editor program, create or change your SQLPLUS report program (also called a start file), and then jump back to SQLPLUS right at the spot you left and run that online shopping system project report report (see Figure 6-1).
SQLPLUS also has a built-in editor of its own, sometimes called the command line editor, which allows you to quickly modify a SQL query without leaving SQLPLUS.
Difference between SQL and SQL Plus:

SQL *PLUS does not require termination character; executes commands immediately.
SQL uses functions to perform some formatting.
SQL *PLUS uses commands to format data.
2.1 Software Development Life Cycle:
Software development organization follows some process when developing a software product. A key component of any software development process is the life cycle model on which the process is based. The particular life cycle model can significantly affect overall life cycle costs associated with a software product. Life cycle of the software starts from concept exploration and at the retirement of the software.
The system development life cycle is classically thought of as the set of activities that online shopping system project report analysts, designers and users carry out to develop and implement an information system. The system development life cycle consists of the following activities:
š Preliminary investigation.
š Requirement Analysis.
š System Designing.
š Coding.
š System Testing.
š Implementation and Maintenance.
Preliminary Investigation: - ONLINE SHOPPING WEBSITE PROJECT
An important outcome of the preliminary investigation is the determination that online shopping system project report system is feasible or not. In the conduct of feasibility study, there are three major distinct and interrelated areas were taken into consideration. They are as follows:
1. Technical Feasibility :
The System of operation which was functioning earlier was totally manual, with no kind of automation or computerization. All the departments were maintaining separate registers for keeping various records. Due to expansion of schools more workspace and it appears a tedious task to maintain with specifying equipment and software that online shopping system project report will successfully support the tasks required. As a result the computerized system is technically feasible as it is efficient, less time consuming, can produce outputs faster, can input large amount of data in limited time scale and easier to use in operation
2. Operational Feasibility : -
The ultimate users i.e. the people who are supposed to use the system are trained for a period of one month so as to get familiar with the new system and its operation. They are taught about the new skills and the new technology and how the technology will be useful to them in their functioning. Operational feasibility is concerned with human, organizational and political aspects. General impression of these factors is gained from the corporate appraisal.
3. Economical Feasibility :
The computerized system is economically feasible in the sense the cost of the hardware and software and the cost to training of personnel of the company to operate the system and the installation cost is less than the cost of maintaining the registers. This online shopping system project may not be a big sum in the long run of the school business. Also the time taken for the entire process of formulation, checking, studying and installation of the project has been equal to one working month of the school. As a result, there has been no hesitation on pert of the management in adopting the new system.
š Requirements analysis:-
Analysis of requirements includes studying the existing system and collecting data. During analysis, data are collected on the available files, decision points and transaction handled by the present system. Once the structured analysis is completed, the analyst has affirmed understanding of what is to be done.
š System Designing:
The design of an information system produces the details that online shopping system project report clearly describe how a system will meet the requirements identified during system analysis. System analysts begin the design process by identifying reports and other outputs system will produce. The system design also describes the data to be input, calculated or stored.
š Coding: -
This online shopping system project is the phase in which computer based system is constructed from the specifications prepared in the design phase. Equipment is acquired and installed during the development phase. All necessary procedure, manuals software specifications, and other documentation are completed. The staff is trained.
š System Testing:-
During system testing, the system is used experimentally to ensure that online shopping system project report the software does not fail. In other words we can say that online shopping system project report it will run according to its specifications and in the way users expect. Special test data are input for processing, and the result examined.
š Implementation, Evaluation and Maintenance:-
Implementation is the process of having systems personnel check out and put new equipments into use, train users, install the new application and construct any files of data needed to use it.
Evaluation of the system is performed to identify its strength and weaknesses. Maintenance is necessary to eliminate errors in the working system during its working life and to tune the system to any variations in its working environment. The importance of maintenance is to continue to bring the new system to standards.
3.1 Overview:
This online shopping system project is the most important step in a software project where we get a general idea about the needs of the customers or end users by having man to man conversation with them and about the various conditions and restrictions that online shopping system project report have to be taken care of while developing the software application.
Analysis is a Fact Finding Technique where studies like User’s need, System Requirement Specifications, Feasibility Analysis and Cost-Benefit Analysis are carried out.
The purpose of this online shopping system project phase is to identify, analyze and document the exact requirements for the system. The developer, customer, a marketing organization, or any combination of the three may perform such study. It is extremely important that online shopping system project report the developers of the system study the existing system thoroughly otherwise it is impossible to satisfy the needs of the user. The requirements at this online shopping system project stage are in end-user terms.
During the Requirement Analysis Phase, the development team analyzes the requirements to be fulfilled by the Online Shoping Cart website and identifies the probable approach for meeting these requirements. To identify the requirements needed by the website, we decided to study the existing Shopping Cart process like Searching Book, Adding to Cart, money transfer. In this online shopping system project phase we have also collect necessary information regarding the details to be stored Registered customer.
3.2 Objective of Requirement Analysis:
Requirement analysis was conducted with the following objectives in mind:
Identification of need
Information Gathering
Evaluate the system concept of feasibility
1. Identification of Need:
The success of the system depends largely on how accurately a problem is defined, thoroughly investigated, and properly carried out through the choice of solution. Users need identification and analysis is concerned with what the user needs rather then what he/she wants. Until the problem has been identified, defined, and evaluated the analyst shouldn't think about solutions and whether the problem is worth solving or not.
2. Information Gathering:
A key part of system development is gathering information. The analyst must know what information to get, where to find it, how to collect it, and how to make use of it. The proper use of tools for gathering information is the key to successful analysis.
3. Feasibility Study:
Feasibility study is carried out to test if the proposed system is feasible in terms of economy, technology, resource availability etc. As such, given unlimited resources and infinite time, all projects are feasible. Unfortunately, such results and time are not possible in real life situations. Hence it is both necessary and prudent to evaluate the feasibility of the project at the earliest possible time in order to avoid unnecessary wastage of time, effort and professional embarrassment over an ill conceived system.

4.1 OVERVIEW: ONLINE SHOPPING WEBSITE PROJECT
System design is a solution, a “HOW TO APPROACH” to the creation of a new system. This online shopping system project important phase is composed of several steps. It provides the understanding and procedural details to implement the system. Design goes through a logical and physical stage of the progress. Logical design reviews the present physical system, prepares input/output specifications, makes audit security and control specifications, detailed implementation plans, and prepares the logical design walkthrough. The physical design makes out the details of the physical system, plans the system implementation and specifies any new hardware and software products.
4.1.1 DATABASE DESIGN:
The collection of data is usually referred to as the database. The database contains the information about one particular enterprise. Database system of data involves both the definitions of structures for the storage of information, processing and mechanism for the manipulation of information. In addition, the database system provides for the safety of information stored in the database despite system crashes or attempts of unauthorized access.
4.1.2 HUMAN-MACHINE INTERFACE DESIGN:
The design of the human machine interface in one of the most important aspects of system design. A good interface design should take into account the following factors: -
User characteristics:
It includes consideration of the kinds of the users who will use the equipment, their diverse backgrounds and skills, the user expectations as well as their physical characteristics. The users who posses high degree of skill often prefer more powerful functions which usually means greater complexity, unskilled operations, on the other hand, would simple functions which are easier to learn and use.
š Task Characteristics:
The nature of the users tasks differ and therefore the needs for specific-kinds of service from the system. For example unstructured tasks usually requires a more flexible mode of interaction to meet the varying needs of users as opposed to structured tasks, which are more predictable and repetitive. The sequence and frequency with which certain tasks are performed will also affect the optimal design of the user interface.
š Functional Characteristics:
It refers to the various functions required to perform the tasks and the ease with which these functions can be learnt made use of by the users while ascertaining the functional characteristics, the support facilities required to perform the functions, also need to be taken into account. These include facilities like training, on line help, documentation, expert system etc. the other aspect of functional characteristics of a system its performance criteria like response time, fault tolerance etc.
š INPUT DESIGN:
The most common cause of errors in data processing is inaccurate input data. Errors entered by data entry operators can be controlled by the input design. Input design is the process of converting user-oriented inputs to computer based formats. The goal of input design to make data entry easy logical and free from errors.
š OUTPUT DESIGN:
Computers are the most important source of information to the user. Inputs are fed into computers to acquire the required outputs. The computers can provide valuable information’s in the form of well-documented outputs for various values. The major form of output is a hardcopy (reports) from the printer. Reports are around the output requirements of the user.
4.2 Software Design Specification:
This online shopping system project section provides an overview of the entire design document. This online shopping system project document describes all data, architectural, interface and component-level design for the software.

7.1.5 System Testing -ONLINE SHOPPING WEBSITE PROJECT
System testing is actually a series of different tests whose primary purpose is to fully exercise the computer-based system. Although each test has a different purpose, all work to verify that online shopping system project report system elements have been properly integrated and perform allocated functions.
7.1.6 OPTIMIZATION POINTS
The software will work efficiently and speedily when the following conditions will be satisfied:
· The server should be of high configuration.
· The client machine has larger RAM.
· Adequate free space on the client’s hard disk.
· The user waits until he gets the home page properly.
· No access to the database for writing, deleting or updating by any other except the authority.
Salient Features of the System
· The software is completely menu driven.
· The data entry screens are completely user friendly.
· All editing features and navigation from one field to another, one web page to another, etc is possible.
· Exit from any web page is possible.
· Validation checks have been incorporated in each web page at the appropriate fields.
· Database has been secured by means of password protection.
· Authorization is necessary for all the internal users of the site.
8. Limitations and Future Development
There are some limitations for the current system to which solutions can be provided as a future development:
The system is not configured for multi- users at this online shopping system project time. The concept of transaction can be used to achieve this online shopping system project.
The Website is not accessible to everyone. It can be deployed on a web server so that online shopping system project report everybody who is connected to the Internet can use it.
Credit Card validation is not done. Third party proprietary software can be used for validation check.
As for other future developments, the following can be done:
1. The Administrator of the web site can be given more functionalities, like looking at a specific customer’s profile, the books that online shopping system project report have to be reordered, etc.
2. Multiple Shopping carts can be allowed.
8.1. Conclusion - ONLINE SHOPPING WEBSITE PROJECT
The Internet has become a major resource in modern business, thus electronic shopping has gained significance not only from the entrepreneur’s but also from the customer’s point of view. For the entrepreneur, electronic shopping generates new business opportunities and for the customer, it makes comparative shopping possible. As per a survey, most consumers of online stores are impulsive and usually make a decision to stay on a site within the first few seconds. “Website design is like a shop interior. If the
shop looks poor or like hundreds of other shops the customer is most likely to skip to the
other site. Hence we have designed the project to provide the user with easy navigation, retrieval of data and necessary feedback as much as possible.
In this online shopping system project project, the user is provided with an e-commerce web site that online shopping system project report can be used
to buy books online. To implement this online shopping system project as a web application we used JSP as the
Technology. JSP has several advantages such as enhanced performance, scalability, built- in security and simplicity. To build any web application using JSP we need a Programming language such as Java and JSP so on. was the language used to build this online shopping system project application. For the client browser to connect to the JSP engine we used Tomcat web server.
JSP uses JDBC to interact with the database as it provides in-memory caching that online shopping system project report eliminates the need to contact the database server frequently and it can easily deploy
and maintain an JSP application. Oracle was used as back-end database since it is one of the most popular commercial databases, and it provides fast data access, easy installation and simplicity.
A good shopping cart design must be accompanied with user-friendly shopping cart application logic. It should be convenient for the customer to view the contents of their cart and to be able to remove or add items to their cart. The shopping cart application described in this online shopping system project project provides a number of features that online shopping system project report are designed to make the customer more comfortable.
This online shopping system project project helps in understanding the creation of an interactive web page and
the technologies used to implement it. The design of the project which includes Data
Model and Process Model illustrates how the database is built with different tables, how
the data is accessed and processed from the tables. The building of the project has given
me a precise knowledge about how JSP is used to develop a website, how it connects to the database to access the data and how the data and web pages are modified to provide the user with a shopping cart application.
