5. Description of System
In Nokia Mobile Store Management System use to maintain their sales
detail in files and folders. They use to keep the record of product sold,
Customers, Suppliers, etc in a register. A daily register is maintained to keep
track of complaints.
Preparing report is very time consuming and tedious task. For searching
of single record, whole register is to be searched which is very time consuming
task.
5
6. Limitations Of Present System
As mentioned above most of details are maintained
manually. Due to this the data retrieved is time
consuming. Due to human calculation errors occur.
Even when the data is maintained on spreadsheet
inconsistency occurs as an order might be missed or
wrongly entered or twice.
Data are stride an excel sheet which takes lot of time and
data may be corrupted.
As storage and exchange of data is achieved only by use
of excel sheets which lack validation capabilities, there is
always risk of invalid, inaccurate or incomplete data
being fed in computer.
Difficulty in managing multiple forms.
Lack of security.
6
7. Proposed System
The proposed system is computerized and has been
developed using advance language therefore it gives more facilities
than present system. It provides quick access to any data. In this system
user have to enter the data only once and then it get linked with all files.
This reduces the workload of user and it is also a time saving process.
The information about any Subscriber can be easily
retrieved. The system maintains all records easy.
7
8. Advantages of Proposed System:
All the information about sale, purchase will be maintain properly in
this system.
All manual calculation of sale or all the money management will be
performed by the computer automatically.
This system will provide timely report information.
It will produce report for sale, bill information.
The computer can hold amount of data in its storage device.
The operation and speed of the computer is very high.
We can calculate result and print any report within seconds.
Any difficulties we can solve easily.
A database application can be stored in computer effectively.
It is very user friendly and easy to handle.
So the computerized system is more suitable than the manual system.

9. Feasibility Of Study
1. Software Specification:-
Software requirements for this system are as listed follows:
FRONTEND : Microsoft Visual Basic 8.0
BACKEND : MS Access-2007
OPERATING SYSTEM : Windows XP
FOR DOCUMENTATION : Microsoft Office
2. Hardware Specifications
Minimum hardware requirements for this System are listed below:
Processor : Pentium-4
RAM : 256MB.
HARD DISK : 80GB.
CD-Rom Driver : Any.

10. FRONTEND: - MICROSOFT VISUAL STUDIO
2008
1. First of all, VB.NET provides managed code execution that runs under
the Common Language Runtime (CLR), resulting in robust, stable and
secure applications. All features of the .NET framework are readily
available in VB.NET.
2. VB.NET is totally object oriented. This is a major addition that VB6 and
other earlier releases didn't have.
3. The .NET framework comes with ADO.NET, which follows the
disconnected paradigm, i.e. once the required records are fetched the
connection no longer exists. It also retrieves the records that are expected
to be accessed in the immediate future. This enhances Scalability of the
application to a great extent.
4. VB.NET uses XML to transfer data between the various layers in the
DNA Architecture i.e. data are passed as simple text strings.
5. Error handling has changed in VB.NET. A new Try-Catch-Finally block
has been introduced to handle errors and exceptions as a unit, allowing
appropriate action to be taken at the place the error occurred thus
discouraging the use of ON ERROR GOTO statement. This again credits
to the maintainability of the code.
6. Another great feature added to VB.NET is free threading against the VB
single-threaded apartment feature. In many situations developers need
spawning of a new thread to run as a background process and increase
the usability of the application. VB.NET allows developers to spawn
threads wherever they feel like, hence giving freedom and better control
on the application.
7. Security has become more robust in VB.NET. In addition to the role-
based security in VB6, VB.NET comes with a new security model, Code
Access security. This security controls on what the code can access. For
example you can set the security to a component such that the
component cannot access the database. This type of security is important
because it allows building components that can be trusted to various
degrees.
8. The CLR takes care of garbage collection i.e. the CLR releases resources
as soon as an object is no more in use. This relieves the developer from
thinking of ways to manage memory. CLR does this for them.
10
11. BACKEND: MS-ACCESS 2007
Microsoft Office Access, previously known as Microsoft Access, is a
database management system from Microsoft that combines the relational
Microsoft Jet Database Engine with a graphical user interface and software-
development tools.
MS Access stores data in its own format based on the Access Jet
Database Engine. It can also import or link directly to data stored in other
applications and databases
Microsoft Access applications can adopt split-database architecture. The
database can be divided into a front-end database that contains the application
objects (queries, forms, reports, macros, and modules), and is linked to tables
stored in a back-end shared database containing the data. The "back-end"
database can be stored in a location shared by many users, such as a file server.
The "front-end" database is distributed to each user's desktop and linked to the
shared database.
Access includes an Upsizing Wizard that allows users to upsize their
databases to Microsoft SQL Server, an ODBC client–server database. An
additional solution, the SQL Server Migration Assistant for Access (SSMA), is
also available for download from
11
12. Stakeholders
Stakeholders are anyone who has an interest in the project. Project
stakeholders are individuals and organizations that are actively involved in the
project, or whose interests may be affected as a result of project execution or
project completion. They may also exert influence over the project’s objectives
and outcomes. The project management team must identify the stakeholders,
determine their requirements and expectations, and, to the extent possible,
manage their influence in relation to the requirements to ensure a successful
project.
The following are examples of project stakeholders:
1. Project Developers :-
Project Developers is one who develops software for customer. In
my project I am the first stakeholder i.e. Project Developer.
2. Project customer :-
Project Customer is one who pays for the developed software.
3. Project user Group :-
Project User group are those people who use the software on
daily basis for the Project Customer.

17. Fact Findings
Introduction
The Current System is the manual one, hence is not speedy, accurate,
efficient as well as time consuming. An essential part of the system analysis,
which enables the developer to understand & the system correctly. It is
undertaken to obtain details of the system. To understand the physical flow of
the information through the current system. Collect various information
through various fact finding techniques. Identify the procedural difficulties
experienced by the user. Study the bottlenecks find out the redundant work
being performed in the system.
Fact Finding Techniques Employed
1. Interviews
Information was obtained from the employees at the organization by
interviewing them at the location and time convention both.
2. Document Searching
An extensive study of existing document an official correspondence
was done to understand the present working status of organization.

SYSTEM CONTROLS AND STANDARDS
1. Access control:-
System gives access by valid password.
2. Input control:-
System validates every textbox. It allows textual values for fields like customer
name. It also validates some numeric data only for fields like phone no.
3. System Generated control:-
In Order details it automatically calculates total price of the product. Similarly in
Receipt details it automatically deducts the amount from the actual amount.
4. Range control:-
In Order Transaction the system checks whether quantity given by the user is not
more than the available product.
96
98. Future Enhancement
Being a computer system, the system has good scope to be
improved further.
Future Enhancements are as listed below
Maintain daily employee attendance.
Administrator can be given more rights so that he will be able
to change order details.
Conclusion
• System helps to store all the data about the customer order in computer
and there is no need to do paper work.
• Data is going to be preserved carefully for longer period hence proper
backup is required otherwise there is chance of losing entries or data.
