CHAPTER II – Project Plan
2 Introduction
This document specific the overall approach applied to the planning phase of the
development cycle. These normally include the team members and the different task
allocated to the team members with response to the time frame provided by the project
manager.
2.1 Scope
The major scope of this system in to develop a web based point of sale software program for
a department store. This POS also include a separate MIS system in order to facilitate the
management part of the store.
2.2 Constraints
Normally constraints are the other important factors for the development cycle. The
following are the considerable constraints for the development of the Sasto Mart POS system.
2.2.1 COST
Cost reflects the competitive advantage of product and marginal utility & value to the clients.
In other word, it’s a pre estimation of the sum of the money required for the software
development. During the development of the POS all the direct as well as indirect cost should
be mentioned.

11
2.2.2 TIME
Time/Resource describes the structure of our group and its ability to fulfil commitments or
the ability to handle changes. For this POS system the project deadline is before 14th
January
2014. Likewise, the maximum human resource allocated was 5.
2.2.3 QUALITY
High quality for the system is maintained so to make the system more reliable and more
efficient. This constraint also can be affected by the total cost and time that is invested for the
completion of the project. So the constraint quality is proportional to the other two constraints
of the system i.e. Cost and the time.

Chapter III Methodology
Available Methodology
There are various types of software development methodologies.
Waterfall model
The waterfall model is a sequential software development model. In other word it is
defined as a process for the creation of software in which development is seen as flowing
steadily downwards like a waterfall in the nature. The origin of the term “waterfall” is
cited to be an article by Winston W. Royce. (Rouse, 2007). The unmodified waterfall
model progress flows from top to the bottom just like a normal waterfall.
The model starts with requirements specification, when the requirement are fully
complete then proceeds to design. This section of design must be the plan for the
implementation of that design by the programmers. Likewise after the implementation
and integration the testing phase is carried out. The error introducted in the earlier pahse
are carried out in the testing phase. Finally the software system is installed and later
maintained to introduce the modification (Sky, 2007).
Figure 2: Figure showing Waterfall model
Advantage Disadvantage
Very easy to implement (Linear) Only able to use when requirement are fixed
Required minimum resource Unable to move back to the previous stage
Documentation is produced at every stages If mistake happen on middle, should start
from the scratch
Testing is done to check code is running
correct or not
Tester role only happen in the test phase
Table 1 Advantages & Disadvantages of Waterfall Model

20
Spiral methodology
The spiral model, also known as the spiral lifecycle model, is a systems development
lifecycle (SDLC) model used in information technology. This model of development
combines the features of the prototyping model and the waterfall model. The spiral model is
favoured for large, expensive, and complicated projects. The Spiral Model is an evolutionary
software process model that couples the iterative nature of prototyping with the controlled
and systematic aspects of the Linear Sequential Model.
In response to the weakness and failure of the waterfall model many new models were
developed that add some form of iteration to the software development process. In spiral
model, the development team starts with a tiny set of requirements and goes through each
development phase (excluding the installation and maintenance phase) for those set of
requirements. Based on the lesson learned through risk analysis process, the development
team adds functionality for additional requirements in every increasing spiral until system
gets ready for installation (Purcell, 2008). Each iteration is prior to the production of version
is a prototype of the application. Hence, it is more recommended to use spiral model when
the cost and risk evaluation is important and the project is complex (better for high risk
project).
Figure 3 Figure showing Spiral Model (Purcell, 2008)

21
Avoidance of risk is enhanced Can be a costly model to use
Good for large and critical projects Risk analysis require highly expertise
personal
Strong approval & document control Project success is dependent on the risk
analysis phase
Additional function can be added at the end Not feasible for small projects
Table 2 Advantages & Disadvantage of Spiral Model
Prototyping
Prototyping is the rapid development of a system. Prototyping can be considered as a risk
reduction activity which reduces requirements risks to help the costumer and the developer
understand the requirement for the system. Prototyping can be part of requirement analysis or
part of the design as well. Prototyping is essential for parts of the system such as the user
interface which cannot be effectively pre-specified. Users must be involved in prototype
evaluation.
By using prototyping model the customer can get an actual view of the system that the
developers are developing. Using the develop prototype can enable a client/customer to get
better understanding of the system. Prototyping model is an effective idea for the
development of the complicated and large systems for which there is no predefined process or
the existing system to help determining the requirements.

Users are involved in the development Leads to implementing and then repairing

22
process way of development
Errors can be detected initially Incomplete application may cause application
not to be used as the full system
Missing functionalities can be identified
easily
Lack adequate problems analysis
Table 3 Advantages & Disadvantage of Prototyping Model
Incremental Model
The incremental model the complete requirement into the different builds, multiple
development cycles take place. A project using incremental model may start with the simple
objectives. Then some portion of these objectives is defined as requirement and implemented.
Meanwhile, using the objectives rather than the requirement can be uncomfortable for
management. A working version of the software is produce during the initial modules which
have to pass through the requirement, design, implementation & testing phase. Each
subsequent release of the module adds function to the initial release. The process continues
till the complete system is formed.
Figure 5 Incremental Model (istqbexamcertification)
More Flexible –less costly to change the
requirement
Needs good planning and design
Generate software quickly Total cost is higher than waterfall

23
Easy to test and debug Needs a clear definition of the system
Easy to manage risk Requirement must be clear and well defined
Table 4 Advantages & Disadvantage of Incremental Model
Rapid Application Development (RAD) Model
Rapid model is rapid application development. It is also called as a type of the incremental
model. In RAD, functions are developed in parallel. The development processes are bound
with the time boxed, delivered and then assembled into a running prototype. This can be very
useful to deliver the project progress to the customer for feedback regarding their
requirements.
Figure 6 RAD Figure (24point0)

24
Reduce development time Needs highly skilled manpower
Increase reusability of components Modularized system can only be built using
RAD
Increase client feedback High dependency on modelling skills
Table 5 Advantages & Disadvantage of RAD Model
Chosen Methodology for Development
As we know that waterfall model is the simple, precise and older established model
till now. This model is used as a immense type’s software and rest of the model is also based
on this model respectively. For the software development process, iterative waterfall model is
preferred which uses the basic concepts starting from analysis i.e. the basic part of the
development and the rest of the required process is also involved here.
The benefits made by this methodology are discussed below:
Figure 7 Iterative Waterfall Diagram

25
1. Analysis: Sufficient problem understanding to write a requirements specification
document.
2. Specification: The required specification that unequivocally communicates the required
quality of the system to the designer.
3. Design: A design document that decidedly communicates the design to the implementers.
4. Implementation: The script code and documentation, prepared to be tested.
5. Testing and Integration: The tested code in operational state.
6. Maintenance: Changes in requirements may require additional performance and testing
or additional design work, or even a new analysis.

26
CHAPTER IV Design Specification
4.1 Introduction:
The objectives of this section of the system specification are to model the proposed system.
The lists of requirements that are gathered in previous chapter are to be design in this chapter.
This section contains different UML diagrams to design the requirements UML stands for
Unified modelling language that is used in OOAD approaches in Software Company. UML is
treated as a rich language that is used to model any business functions, structures.
4.2 Purposes
The main purpose of design specification document is as follows:
i) Design specification document is used for various functions from laying out plans for
a new space ship to addressing the design concerns of the system.
ii) Provide the hawk eye structure of the project through different pictorial
representation.
iii) The expectations of user are documented, and are agreed by the users and developer
team.
iv) It involves the thorough data, functional requirements and behavioral requirements.
v) It clears the way to the programmers giving the plan and guidelines on how the
software necessity ought to be actualized.
vi) The design document additionally ensures that the present design sums up all the
explicit necessities of the arrangement ideal and additionally the inherent necessities
anticipated by the customer.
4.3 Intended Audience and Reading Suggestion:
The intended audience for this document is most likely the project owner and somehow we
can integrate users of the system also.
4.3.1 Project Owner: For any academic project the project owner simply justly the
involvement of the academic institutions that’s why Islington College virtually stay as the
project owner of this project
4.3.2 Programmer: Programmer refers the students who is undertaking the project and
responsible for all the sort s of development process in software engineering.
4.3.3 User: The user will be implementing and bringing the system in use. The User Interface
(UI) will be shared among the different users.

27
4.4 System Architectural Design
A presently instituted Sasto Mart is the accepted departmental store placed at New
Road, needs a POS arrangement for the sales of items and commodities. The POS
Arrangement to be installed in at least 4 counters alongside the maximum catering capacity of
3 clients at one every single counter possessing a computing mechanism, bar program
scanner, a dot matrix bill printer and a POS application.
During every single shopping, the client comes to the counter alongside the items
bought and the staffs at the counter scans the items via Barcode scanner next the scanned
items data is dispatch to the computer whereas the POS request is installed and the
arrangement performs the more calculations. In case of failure, the staffs need to ender the
details manually. The discount details are also automatically deducted as offered by the
department store. On payment conformation, the POS should generate the receipt for the
required transactions. All the operation handled by the POS is connected to the server
database through LAN.
4.4.1 MVC (Model View Controller)
Figure 8: MVC Architecture

28
Model–view–controller (MVC) is a software outline for implementing the user
interfaces. It divides the software into three interconnected portions to distinct inner
representations of data from the methods that data gave to or consented from the user
4.4.1.1 A model notifies its associated sights and controllers after there has been a change in
its state. This notification permits the sights to produce notified output, and the controllers
to change the obtainable set of commands. A passive implementation of MVC omits these
notifications, because the request does not need them or the software period does not
support them.
4.4.1.2 A view requests information from the model that it needs for obtaining an output
representation to the user.
4.4.1.3 A controller can launch commands to the model to update the model's state. It can
also send commands to its associated view to change the view's presentation of the model.

Client server architecture partially divides the complete system into three different aspects
which include the database server, a main server as well as a client system. In this Sasto mart
system the four different POS terminal would react as the client system, a database server
system will be available for the storage during the business procedure. Likewise a main
server will be available for interpreting the database into the client terminal.
