1. INTRODUCTION & OBJECTIVES OF THE PROJECT

1.1 INTRODUCTION

This is a Project work is undertaken in context of partial fulfillment of the MCA.

At Samsung Mobile Repairing Center, experienced mobile engineers can perform

prompt service on all makes and models of the Samsung Mobiles. The qualified
technical staff diagnoses challenging problems for all models. Online users and
customers can send their Samsung mobiles Repair Request , to get free Mobile
Repair Estimate.

Simply after filling the Mobile repair estimate form service center will send the
customers estimate. If the customer accepts the estimate service center will start
repairing the Mobile. Samsung mobile repairing engineers are experienced in
troubleshooting and fixing the most challenging problems. Moreover, if a
customer has faulty or broken mobile sitting around not being used, Samsung
Service center will buy it from the customer at a fair price. Users have to click
Sell your Mobile and provide service center with some information about the
mobile. Samsung Mobile Service Center will respond shortly with an offer. I am
confident that this software package can be readily used by non-programming
personal avoiding human handled chance of error. This project is used by two
types of users

i. Online Users.
ii. Administrator (management of the company).

Online users can check their service details, service center details, repair estimate
etc. Administrator can maintain daily updates in the records. Administrator is
must be an authorized user. He can further change the password. There is the
facility for password recovery, logout etc.

1.2 OBJECTIVES OF THE PROJECT

The objectives of the project are to:

i. Develop a functional & usable Samsung Mobile Service Center

Management System.

ii. This Website is useful for the users who are interested in Mobile

repairing from authorized service centers.

iii. This Website is useful for users as follows:

• To get servicing tips to save money on repairing by repairing your Mobile

yourself.

• Users can further get the information of the Showrooms and Service

centers.

• To get upgrade and repair manuals.

• To get collection of free take apart instructions, guides, disassembly

pictures.

• To get do-it-yourself (DIY) tips and tricks to fix mobile (portable)

phones made by Samsung.

iv. This Website is useful for Administers as follows:

• To add Mobile details sold from a particular showroom.

• Add servicing details of the Mobile.

• Add service centers details.

• To store details of the stock available.

• Collecting Feedbacks from the customers or users.

-8- Baluja Labs

 Baluja Labs

• Report Generation

• Add information about the accessories and spare parts available in

the company.

• To get rates of new Mobiles.

• To sale you old Mobiles.

Proposed System

1. The web-site is to be accessed from any where anytime.

2. As the project is web-based so the software should be platform independent.

3. The data is very important asset for corporation so strong authentication

method is to be used to ensure security of information from malicious user.

4. As the valuable data is being transferred through internet so the security of

data is to be maintained at any cost.

5. Easy to be customized in future. As the client demand some other additional

features. The complexity of customer’s company may be different or if mode of
business changes then the system has capability to make appropriate
modification to suite that change. Customization is key factor of designing this
software.

6. The web-site manipulates data in an accurate way.

7. Accuracy of all type of calculations are important and to be achieved at any
cost.
8. This should always be observed during the development of the software that
the user is not from technical background, so the software should be user friendly
and can be handled easily.

-9- Baluja Labs

 Baluja Labs

9. Storage of data should be easily accessible.

10. The data retrieval and other manipulation related task which is done at the
database level should be fast enough. The database should support multiple
users at a time.
11. The product should fulfill user’s requirement.

1.3 ADVANTAGE

I have designed the given proposed system in the ASP and SQL SERVER to

automate the process of Sumsung Mobile Service Centre Management System.

Performance: During past several decades, the records are supposed to be

manually handled for all activities. The manual handling of the record is time
consuming and highly prone to error. To improve the performance of the
Company system, the computerized system is to be undertaken. The
computerized project is fully computerized and user friendly even that any of the
members can see the report and status of the company.

Efficiency: The basic need of this website is efficiency. The website should be
efficient so that whenever a new user submits his/her details the website is
updated automatically. This record will be useful for other users instantly.

Control: The complete control of the project is under the hands of authorized
person who has the password to access this project and illegal access is not
supposed to deal with. All the control is under the administrator and the other
members have the rights to just see the records not to change any transaction or
entry.

Security: Security is the main criteria for the proposed system. Since illegal access
may corrupt the database. So security has to be given in this project.

1.4 DRAWBACKS OF CURRENT MANUAL- SYSTEM

• The current manual system has a lot of paper work and it does not deal

with exact record details.

• To maintain the records of sale and service manually, is a Time-consuming

job.

• With the increase in database, it will become a massive job to maintain the

database.

• Requires large quantities of file cabinets, which are huge and require quite

a bit of space in the office, which can be used for storing records of

previous records.

• The retrieval of records of employees, customers, trouble tickets will be a

tedious job.

• Lack of security for the records, anyone disarrange the records of your

system.

ESTABLISH THE NEED OF NEW SYSTEM

1. Problem of Reliability: Current system is not reliable. It seems to vary in

quality from one month to the next. Some times it gives good output, but
some times the output is worst.

2. Problem of Accuracy: There are too many mistakes in reports.

- 11 Baluja Labs
-
 Baluja Labs

3. Problem of timeliness: In the current system the reports and output

produced is mostly late and in most of the cases it is useless because it is not
on time.

4. Problem of Validity: The output and reports mostly contains misleading

information. The customer's information is sometimes not valid.

5. Problem of Economy: The current system is very costly. We have to spend

lots of money to keep the system up and going, but still not get the desired
results.

6. Problem of Capacity: The current system is suffering from problem of

capacity also. The staff for organization is very less and the workload is too
much. Few peoples cannot handle all the work.

1.6 NEED

I have designed the given proposed system in the ASP.NET to automate the
process of Sumsung Mobile Service Centre Management System. This project is
useful for the authorities who keep track of all the Sumsung Mobile Service
Centre Management System.
The following steps that give the detailed information of the need of proposed
system are:
• Performance: During past several decades, the records are supposed to be
manually handled for all activities. The manual handling of the record is time
consuming and highly prone to error. To improve the performance of the
system, the computerized system is to be undertaken. The computerized
project is fully computerized and user friendly even that any of the members
can see the report and status of their enquiries.

• Efficiency: The basic need of this website is efficiency. The website should be
efficient so that whenever a new user submits his/her details the website is
updated automatically. This record will be useful for other users instantly.

• Control: The complete control of the project is under the hands of authorized
person who has the password to access this project and illegal access is not
supposed to deal with. All the control is under the administrator and the
other members have the rights to just see the records not to change any
transaction or entry.

• Security: Security is the main criteria for the proposed system. Since illegal
access may corrupt the database. So security has to be given in this project.

SOFTWARE & HARDWARE REQUIREMENTS

The need of today’s software development is competence in a GUI based front-

end tool, which can connect to Relational Database engines. This gives the
programmer the opportunity to develop client server based commercial
applications.

FRONT END

.NET programming tools are complete programming environments. It allows

programmers to build a GUI program using the various on-screen controls such
as buttons, text, menus, boxes etc. These controls are placed on a form and then
the processing details related with each control are filled in.

In the business world, competitive strategies have become the order of the day to
improve quality, cut costs and provide a high response customer service base.
Most organizations today need to be market driven and do a lot of value addition
to their products and services. This naturally calls for rational decision making,
which requires information. Information Technology or IT provides that effective
channel to support and implement this strategy. Client/Server is the technology
that empowers the desktop, thus setting a trend for the way successful
organizations will use technology in the next decade.

 Baluja Labs

• Supports the software lifecycle

o Development
o Debugging
o Deployment
o Maintenance
Application Architectures
• The Different types of Applications may vary from single-tier desktop
applications (applications that follow the single-tier architecture) to multi-
tier applications (applications that follow the two-, three, or n-tier
architecture)
• Single-tier architecture
o A single executable file handles all functions relating to the user,
business, and data service layers.
• Two-tier architecture
o Divides an application into the following two components:

Client

Server
• Three-tier architecture
o All the three service layers reside separately, either on the same
machine or on different machines.
• n-tier architecture
o Uses business objects for handling business rules and data access.
o Has multiple servers handling business services.

The .NET Initiative

• The introduction of the Internet and its rapid growth in the recent past has
led to the development of a number of new Technologies.
• One of the most important requirements of such applications is the ability
to interchange information across platforms and to benefit from the
functionality provided by other applications.

- 18 Baluja Labs

 Baluja Labs

• In the current scenario, although applications serve organization-

specific requirements, they are not interoperable. Microsoft has introduced
the .NET initiative with the intention of bridging the gap in
interoperability between applications.
• The .NET initiative offers a complete suite for developing and deploying
applications, which consists of the following:
o NET products: Microsoft has already introduced Visual Studio
.NET, which is a tool for developing NET applications by using
programming languages such as Visual Basic, C#, and Visual C++.
o NET services: Microsoft is coming up with its own set of Web
services, known as My Services. These services are based on the
Microsoft Passport Authentication service, the same service that is
used in Hotmail.

Explanation of the .NET Framework

• Is a collection of services and classes?
• Exists as a layer between .NET applications and the underlying operating
system.
• Encapsulates much of the functionality, such as debugging and security
services.
• The following figure depicts the components of the .NET Framework:

The .NET Framework Base Classes or the .NET Class Framework

• Consists of a class library that works with any .NET language, such as
Visual Basic .NET and C#.
• Provides classes that can be used in the code to accomplish a range of
common programming tasks.
• Comprises
o Namespaces: Namespaces help you to create logical groups of
related classes and interfaces that can be used by any language
targeting the .NET Framework.

ADO.NET
• Is a model used by Visual Basic .NET applications to communicate with a
database for retrieving, accessing, and updating data?
• Uses a structured process flow to interact with a database.

ADO .NET Data Access

Most applications need data access at one point of time making it a crucial
component when working with applications. Data access is making the
application interact with a database, where all the data is stored. Different
applications have different requirements for database access. ASP.NET uses
ADO.NET (Active X Data Object) as it's data access and manipulation protocol,
which also enables us to work with data on the Internet. Let's take a look why
ADO.NET came into picture replacing ADO.

Evolution of ADO.NET

The first data access model, DAO (data access model) was created for local
databases with the built-in Jet engine which had performance and functionality
issues. Next came RDO (Remote Data Object) and ADO (Active Data Object)
which were designed for Client Server architectures but soon ADO took over
RDO. ADO was a good architecture but as the language changes so is the
technology within it. With ADO, all the data is contained in a record set object
which had problems when implemented on the network (Internet) and
penetrating firewalls. ADO was a connected data access which means that when
a connection to the database is established the connection remains open until the
application is closed, which raises concerns about database security and network
traffic. And also as databases are becoming increasingly important and as they
are serving more people a connected data access model makes us think about its
use. For example, an application with connected data access may do well when
connected to two clients, the same may do poorly when connected to 10 and
might be unusable when connected to 100 or more. Also, open database

- 21 Baluja Labs
-
 Baluja Labs

connections use system resources to a maximum extent making the system

performance less effective.

Why ADO.NET?
To cope up with some of the problems mentioned above, ADO.NET came into
existence. ADO.NET addresses the above mentioned problems by maintaining a
disconnected database access model which means that when an application
interacts with the database the connection is opened to serve the request of the
application and is closed as soon as the request is completed. Likewise if a
database is updated, the connection is opened long enough to complete the
Update operation and is closed. By keeping connections open for only a
minimum period of time ADO.NET conserves system resources and provides
maximum security for databases and also has less impact on system
performance. Also, ADO.NET when interacting with database uses XML by
converting all the data into XML and using it for database related operations
making them more efficient.

Features of ADO.NET

• Disconnected data architecture — Applications connect to the database

only while retrieving and updating data.
• Data cached in datasets — ADO.NET is based on a disconnected data
structure. Therefore, the data is retrieved and stored in datasets.
• Data transfer in XML format — ADO.NET uses XML for transferring
information from a database into a dataset and from the dataset to another
component.
• Interaction with the database is done through data commands.

4.1 SYSTEM DESIGN

The design document that we will develop during this phase is the blueprint of
the software. It describes how the solution to the customer problem is to be built.
Since solution to complex problems isn’t usually found in the first try, iterations
are most likely required. This is true for software design as well. For this reason,
any

in the real world. That is, the structure of the software design should (whenever
possible) mimic the structure of the problem domain.

The design should exhibit uniformity and integration. A design is uniform if it

appears that one person developed the entire thing. Rules of style and format
should be defined for a design team before design work begins. A design is
integrated if care is taken in defining interfaces between design components.

The design activity begins when the requirements document for the software to
be developed is available. This may be the SRS for the complete system, as is the
case if the waterfall model is being followed or the requirements for the next
"iteration" if the iterative enhancement is being followed or the requirements for
the prototype if the prototyping is being followed. While the requirements
specification activity is entirely in the problem domain, design is the first step in
moving from the problem domain toward the solution domain. Design is
essentially the bridge between requirements specification and the final solution
for satisfying the requirements.

The design of a system is essentially a blueprint or a plan for a solution for the
system. We consider a system to be a set of components with clearly defined
behavior that interacts with each other in a fixed defined manner to produce
some behavior or services for its environment. A component of a system can be
considered a system, with its own components. In a software system, a

Relationships: Data objects are connected to one another in a variety of different

ways. We can define a set of object relationship pairs that define the relevant
relationships.

 CARDINALITY AND MODALITY:

Cardinality:
The data model must be capable of representing the number of occurrences of
objects in a given relationship. The cardinality of an object relationship pair is

♦ One-T0-One (1:1): An occurrence of object ‘A’ can relate to one

and only one occurrence of object ‘B’ and vice versa.
♦ One-To-Many (1:N): One occurrence of object ‘A’ can relate to
one or may occurrences of object ‘B’ but an occurrence of object
‘B’ can relate to only one occurrence of object ‘A’.
♦ Many-To-Many (M: N): An occurrences of ‘B’ and an
occurrence of ‘B’ can relate to one or many occurrence of ‘A’.

Modality:

- 33 Baluja Labs
-
 Baluja Labs

The modality of a relationship is zero if there is no explicit need for the

relationship to occur or the relationship is optional. The Modality is one if the
occurrence of the relationship is mandatory.

The object relationship pair can be represented graphically using the Entity
Relationship Diagrams. A set of primary components are identified for the Entity
Relationship Diagram,

1. Attributes,
2. Relationships and
3. Various Type Indicators.
The primary purpose of the Entity Relationship Diagram is to represent data
objects and their relationships.

ed to be added the corresponding forms are opened and the database is

manipulated to check whether the data is already existing or not. If it already
exists, then it prompts that “Entry already existing” and if not than the data is
entered with the various validation checks.

Modifying / Updating Existing Entities

In this module, whenever an existing entity is required to be modified the
corresponding forms are opened and the database is manipulated and the data is
fetched. Now the administrator can made the required changes and then
accordingly, he updates the data. Again, the checks are followed in case there is
any invalid entry.

Searching
In this module, whenever an existing entity is required to be searched the
corresponding forms are opened and the database is manipulated and the data is
fetched. Again, the checks are followed in case there is any invalid entry.

Servicing

 Baluja Labs

In this module, servicing details of all the Mobiles is stored in the database. This
database will be uploaded so that, if a user or customer who wants to service a
Mobile can check his/her servicing details. There are some conditions and
durations for servicing. Suppose a customer has purchased a Mobile from any
showroom of SAMSUNG then he can get services from any authorized service
center of the SAMSUNG.

Showroom_details
In this module, detail of all the showrooms is stored in the database. This
database will be uploaded so that, if a user or a customer who wants to purchase
a Mobile can check about the Samsung Mobile showrooms.

Owners
In this module, detail of the owners of the Mobile is stored in the database. This
database will be uploaded so that, if a user or a customer who wants the services
from any authorized service centers can be tracked.

Repair Estimates
If a customer is interested in repair of their Mobile, he can fill a form and can get
the repair estimate from the service center.

Service Tips
In this module, service tips are provided to the customers so that they can save
their money.

Emails
In this module, Administrator can inform or remind all the customers whose
service is due; this will be checked automatically from the database.

Admin Panel
This module is useful for the administers as follows:

5.2 CODE EFFICIENCY

Reviewing of Code efficiency for a module is carried out after the module is
successfully compiled and all the syntax errors eliminated. Code efficiency
review is extremely cost-effective strategies for reduction in coding errors in
order to produce high quality code. Normally, two types of efficiency are carried
out on the code of a module - code optimization and code inspection. The
procedure and final objective of these two efficiency techniques are very different
as discussed below.

5.3 OPTIMIZATION OF CODE

Code optimization is an informal code analysis technique. In this technique, after

a module has been coded, it is successfully compiled and all syntax errors are
eliminated. Some members of the development team are given the code a few
days before the

One of the purposes of the testing is to validate and verify the system.
Verification means checking the system to ensure that it is doing what the
function is supposed to do and Validation means checking to ensure that system
is doing what the user wants it to do.

No program or system design is perfect; communication between the user and

the designer is not always complete or clear, and time is usually short. The result
is errors and more errors. Theoretically, a newly designed system should have all
the pieces in working order, but in reality, each piece works independently. Now
is the time to put all the pieces into one system and test it to determine whether it
meets the user's requirements. This is the best chance to detect and correct errors
before the system is implemented. The purpose of system testing is to consider all
the likely variations to which it will be subjected and then push the system to its

limits. If we implement the system without proper testing then it might cause the
problems.
iques. This type of testing plays very important role in increasing the systems
productivity. We have checked our system by using the integration testing
techniques.

3. SYSTEM TESTING:
A part from testing the system to validate the functionality of
software against the requirements, it is also necessary to test the non-functional
aspect of the system. Some examples of non-functional tools include tests to
check performance, data security, usability/user friendliness, volume,
load/stress that we have used in our project to test the various modules.

System testing consists of the following steps:

1. Program(s) testing.
2. String testing.
3. System testing.
4. System documentation.
5. User acceptance testing.

both activities. Together, they are often called V&V activities.

The major V&V activities for software development are inspection, reviews, and
testing (both static and dynamic). The V&V plan identifies the different V&V
tasks for the different phases and specifies how these tasks contribute to the
project V&V goals. The methods to be used for performing these V&V activities,

the responsibilities and milestones for each of these activities, inputs and outputs
for each V&V task, and criteria for evaluating the outputs are also specified.

The two major V&V approaches are testing and inspections. Testing is an activity
that can be generally performed only on code. It is an important activity and is
discussed in detail in a later chapter. Inspection is a more general activity that can
be applied to any work product, including code. Many of the V&V tasks are such
that for them, an inspection type of activity is
