Synopsis

This is a small scale project for Online shopping system.The basic
idea is that customer’s can buy products using online. It consists of
product details, security system, status and exits. The administrator can
enter the name and password and generate the report and can perform
operations like add , search, delete the products in the database.

The Online Shopping system enables vendors to set up online
shops, customers to browse through the shops, and a system administrator
to approve and reject requests for new shops and maintain lists of shop
categories.Also on the agenda is designing an online shopping site to
manage the items in the shop and also help customers purchase them
online without having to visit the shop physically.Our online shopping
mall will use the internet as the sole method for selling goods to its
consumers. Shopping will be highly personalized and the mall will
provide lower prices than most competitors.

Phase 1 Project Analysis and Planning
1.1. Study of the Problem
The Current shopping System is critical to set up online shops, customers to
browse through the shops, and a system administrator to approve and reject requests
for new shops and maintain lists of shop categories. This is a small scale project for
Online shopping System. The basic idea is that the candidates can buy product from
anywhere during any time by using their card number and password provided to them.
The database will maintain the product details information. Customer can view their
product details using the card details. This Online shopping system involves with two
types of users.
• CUSTOMER
• ADMINISTRATOR

CUSTOMER ROLE:
The customer’s can login/logout the System. He/She can view his/her product
details and buy their product. The customer can just view the information whereas
he/she could not make changes in the database.

ADMINISTRATOR ROLE:
The administrator plays a vital role in the Online shopping system. The
administrator controls the entire database. The report of the product is generated by
the administrator itself. The main role of the administrator is to safeguard the database
and can add/delete the products from the database.

1.2. Project Scope
The supplementary specification applies to online shopping system.
This specification defines the non-functional requirement of the system such as:
Functionality:
Since it stand alone application, one or more user may use it at a time.
Usability:
Desktop interface
Windows 98/2000/XP/7

09CSA10

Reliability:
The system is available during online time only .
Performance:
The performance depends on hardware specification

1.3. Objectives
The purpose of this document is to define the requirements of Online
shopping system. This supplementary specification lists the requirements that are not
readily captured in the use case model. Supplementary specification and the use case
model capture a complete set of requirement of the system.

Phase 2 Cost Estimation
An estimate is a prediction based upon probabilistic assessment. It is the
responsibility of the project manager to make accurate estimations of effort and cost.
This is particularly true for projects subject to competitive bidding where a bid too
high compared with competitors would result in loosing the contract or a bid too low
could result in a loss to the organization. This does not mean that internal projects are
unimportant. From a project leaders estimate the management often decide whether to
proceed with the project. Industry has a need for accurate estimates of effort and size
at a very early stage in a project. However, when software cost estimates are done
early in the software development process the estimate can be based on wrong or
incomplete requirements. A software cost estimate process is the set of techniques and
procedures that organizations use to arrive at an estimate. An important aspect of
software projects is to know the cost. The major contributing factor is effort.

Why SCE is difficult and error prone ?
• Software cost estimation requires a significant amount of effort to perform it
correctly.
• SCE is often done hurriedly, without an appreciation for the effort required.
• You need experience at developing estimates, especially for large projects.
• Human bias i.e. An Estimator is likely to consider how long a certain portion
of the system would take, and then to merely extrapolate this estimate to the rest of
the system, ignoring the non-linear aspects of software development.

09CSA10

The causes of poor and inaccurate estimation
• New software projects are nearly always different form the last.
• Software practitioners don't collect enough information about past
projects.
• Estimates are forced to match the resources available.

2.1. Cost and Pricing
Our project is of high range and is highly efficient which can satisfy the shopping
calculation for almost all software companies. The chances of error occurrence is very
limited and so our costs around Rs 10, 00,000(app).
• A team of 11 members is required for completing the task.
• It takes a time span of 3 weeks to shape the project.
• There are no specific environmental constraints.

Phase 3 Modeling the Requirements
3.1. Module Description
3.1.1. Login
It is the login session for the Administrator, customer and Exit.
3.1.2. Product Details
It is used to view the product details from the database.
3.1.3. Add New Products
It is used to add a product into the database and it includes searching a product
details and removing a product from database.
3.1.4. Updating The Quantity
It is used to update the product details from the database.

3.2. UML Diagram
3.2.1. Use case Diagram
Use Case diagrams show the various activities the users can perform on the
system. The System is something that performs a function. They model the dynamic
aspects of the system. It provides a user’s perspective of the system.
Actor:
An actor is a user of the system playing a particular role.
Use case:
Use case is a particular activity a user can do on the system.
Relationship:
Relationships are simply illustrated with a line connecting actors to use cases.

3.2.2. Class Diagram
A class diagram describes the types of objects in the system and the various
kinds of static relationships that exist among them.i.e.,A graphical representation of a
static view on declarative static elements. A class is the description of a set of objects
having similar attributes, operations, relationships and behavior.

3.2.3. Sequence Diagram
A sequence diagram in Unified Modeling Language (UML) is a kind of
interaction diagram that shows how processes operate with one another and in what
order. It is a construct of a Message Sequence Chart. Sequence diagrams are
sometimes called event diagrams, event scenarios, and timing diagrams.

3.2.4. Collaboration Diagram
A Collaboration diagram is very similar to a Sequence diagram in the purpose
it achieves; in other words, it shows the dynamic interaction of the objects in a
system. A distinguishing feature of a Collaboration diagram is that it shows the
objects and their association with other objects in the system apart from how they
interact with each other. The association between objects is not represented in a

09CSA10

Sequence diagram. A Collaboration diagram is easily represented by modeling objects
in a system and representing the associations between the objects as links. The
interaction between the objects is denoted by arrows. To identify the sequence of
invocation of these objects, a number is placed next to each of these arrows.

Phase 4 Configuration Management
Configuration management is also used in software development, where it is
called Unified Configuration Management (UCM). Using UCM, developers can keep
track of the source code, documentation, problems, changes requested, and changes
made. An advantage of a configuration management application is that the entire
collection of systems can be reviewed to make sure any changes made to one system
do not adversely affect any of the other systems

Phase 5 Software Testing
5.1. Preparing Test Plan
Preparing test plan is the first step in the last phase of software development
cycle .The test plan consists of all the activities that had to be done in the software
testing phase. This test plan has been documented using the rational test manager
software.
5.2. Perform Validation Testing
Software is completely assembled as a package interfacing errors have been
uncovered and a final series of software test validation testing may begin. Validation
successive when the customer is satisfied.

09CSA10

5.3. Validation Test Criteria
Software validation is achieved through a series of black box test that
demonstrates conformity with requirements.
5.4. Coverage Analysis
Coverage analysis is used to identify untested code. Using rational pure
coverage, untested code can easily be identified.
5.5. Memory Leaks
Memory leak testing has been done using rational purity software.
