PROJECT DESCRIPTION

NAME OF THE PROJECT: MOBILE STORE MANAGMENT

Following are few characteristics of the Mobile Management System

Referential Integrity of relational Database is followed

Use of shortcuts t access different processes is provided for the user having

computer knowledge

User-Friendly prompts are provided for user.

Attractive and catch Graphical & Photographic Interfaces are used for user

interaction

Data reports allow generation of reports dynamically with desired query.

Strong management system controls are used easy Navigation is provided for

maintaining proper flow of system.



LIMITATIONS OF THE PRESENT SYSTEM

The current system has several shortcomings that are as follows:-

The existing system was not very effective & was highly time consuming.

The current system works manually.

The existing system was somewhat paper-based (paper-work).

Which takes time?

The rate at which the work done is very slow due to non-utilization of

computerized system.

It does not provide better data facilities as well as data availability on

fingertip.

Inconsistency was the major problem in the existing system as there is no

proper facility was provided to update the data.

In case user wants to find out details of particular Mobiles whole database

records are displayed.

It is difficult to remember all data

Consumes large volume of paper work

Large storage space is required to keep to the files and register in proper

coordination’s

In the present system the report generation becomes very difficult.



PROPOSED SYSTEM

This system computerizes all data is storing all data of the Mobiles Sales, Customer Details, Employee Details along with Salary.

Validation at the time of entering data, so no chance of duplication of data.

Extensive Validation on input record so that no changeable record are Prone to error.

Response time for the query should be minimized.

To keep data base up to date by regular updating.

Reduce the cost of maintaining system.

To provide various report facility.

Cost effective and less manpower required.

ADVANTAGES OF PROPOSED SYSTEM

The new system would easily overcome most of the short coming of the

current system.

Owner can see the fine report.

Not much manual work is involved.

Ensure data accuracy

Security of data is done

Save a lot of time and effort

Optimize processing time.

User friendly system.



LIMITATION OF PROPOSED SYSTEM

Only one person can use the system.

The system prepared is competent but we cannot say that it is a perfect system.

This system like any other system has some flaws & shortcomings in it. They

are as follows:

o This system is semi-functional. This means that the system covers the

manipulation related to the record only.

o There would be high rate & better quality of performance.



PROCESSING ENVIRONMENT

Processing environment includes hardware and software requirements.

Software Requirement

Operating system: - Windows XP, Windows7Front-end Tool: - Visual studio 2008Back-end Tool: - MS SQL2005

Hardware Requirement

Operating system: Windows XP and above.Minimum 5 GB HDD space3.00 Megahertz Intel Pentium IV Processor1 GB RAM



FEASIBILITY STUDY

The feasibility study plays a major role in the analysis of the system. The very decision of the system analysis whether he should design a particular system or not and till what extend or limits the very project should be stretched can be inferred from the system feasibility study. Hence the feasibility study forms the basis of the system. The feasibility system can be categorized into:

Technical Feasibility:-It determines the technology needed for the proposed system is available and

how this technology can be integrated into the organization. Technical evaluation must also access whether the existing system can be upgraded to use the new technology and whether the organization has the expertise to use it. Genuine Computer is equipped with the necessary hardware and software.

Software Available Microsoft Windows 98, XP. Microsoft Office.

Hardware Available Intel Pentium IV Processor. 256 MB RAM. 3.5” Floppy Disk Drive. HP Printer. DVD Rom

Organizational and Culture Feasibility:-The organizational and culture feasibility analysis is done to scrutinize whether the system sits up with the working environment and the organizational discipline and rules.Following issues are considered:

The current level of computer competency. Re-engineering the old working procedures. Substantial tech phobia. Expectation of the users.



Operational Feasibility:-The proposed system will automated the existing manual system and make it

user friendly. With the required training the users will find the system easier to operate. The systems cuts down the time delay of the existing manual system.

Economic Feasibility:-The economic feasibility of the system looks upon the financial aspects of the

system. It determines whether the project is economically feasible. In other words, It determines whether the investment that goes into the implementation of the project is recoverable. The cost benefit analysis is a commonly used method in evaluating the effectiveness of the system. As the hardware is already available and no investment is to be made in that direction, the only cost involved is that of implementing the system and software.

Resource Feasibility: -A resource feasibility test was conducted to check the following things

Availability of manpower The necessary skills and support on behalf of the staff.Availability of necessary infrastructure

This test produced the following results:-

First & foremost, each & every functions of each type of user is well defined.

System has a very user friendly environment.

Roles of each user are very well defined.

CHAPTER 2

SYSTEM ANALYSIS



STAKE HOLDERS

Stake holder is a party that can affect or be affected by the actions of the business as a whole.

TYPES OF STAKE HOLDERS:

INTERNAL STAKE HOLDER -Internal stake holders-Market (or primary)Stake holders are those that are

engaged in economic transactions with the business.

EXTERNAL STAKE HOLDERS-Non market(or secondary) stake holders are those who although they do

not engaged in direct economic exchange with the business are affected by or can affect its actions.

STAKEHOLDERS IN THIS SYSTEM ARE AS FOLLOWS:-

EMPLOYEESHe actually works 24/7 to grow business. Honest, open communication with them will Impress the rest of stake holders and

Result in sales and profit. Company will be affected if employees are not honest, loyal. Employees are affected if wrong data is inserted.

CUSTOMERCustomer will be affected if he does not get delivery of Mobiles on time. He

may cancel next order or do not give order at all. This will adversely affect the company. Company should satisfy clients demand on time.

ADMINISTRATORThe owner of the admission system needs to keep a check on everything which is visiting admission system about each and every registration and viewing and making changes i.e. update, delete etc. this is one of the important issue to be handled . Industry should be kept on changing according to the staffs and liking of the Customer/Owner

FACT FINDING TECHNIQUES



Informationandthorough knowledge as well as on job training plays a very important role in any organization. Acquiring valuable information is essential for developing a new system in an organization. There are many ways of gathering information. But the following things need to be kept in mind while gathering information.

No system details are left out. Problems are correctly identified. Repetitive work is avoided. Following are the fact finding techniques:-

o Structured interview

o Mechanical knowledge skills

o Questionnaires

o Record inspection

o Observation

Structured Interview This method is used to collect the information from groups or individuals. Analyst selects the people who are responsible and related with the system for the interviewer. In this method the analyst had dialog and discussion in person or telephonic conversation.

Record InspectionThe information related to the system is published in the sources like newspapers, magazines, journals, documents etc. This record review helps the analyst to get valuable information about the system and the organization.

Observation Unlike the other fact finding techniques, in this method the analyst himself visits the organization and observes and understand the flow of documents, working of the existing system, the users of the system etc. For this method to be adopted it takes an analyst to perform this job as he knows which points should be noticed and highlighted. In analyst may observe the unwanted things as well and simply cause delay in the development of the new system

EVENT TABLE

USE CASE



A use case diagram in the Unified Modeling Language (UML) is a type of

behavioral diagram defined by and created from a Use-case analysis. Its purpose is

to present a graphical overview of the functionality provided by a system in terms

of actors, their goals (represented as use cases), and any dependencies between

those use cases.

Product Detail



Customer Detail

Employee Detail


Represent Data Entity.

Represent connection Administrator

Represent the relationship.

Symbols used in Entity-Relationship Diagram are as follows:

Connect two Entities or One to One relation.


Invoice Detail Subsystem

ER-DIAGRAM



An entity-relationship (ER) diagram is a specialized graphic that illustrates the interrelationships between entities in a database. ER diagrams often use symbols to represent three different types of information. Boxes are commonly used to represent entities. Diamonds are normally used to represent relationships and ovals are used to represent attributes.

ACTIVITY DIAGRAM



Activity diagrams are graphical representations of workflows of stepwise activities and actions with support for choice, iteration and concurrency. In the Unified Modeling Language, activity diagrams can be used to describe the business and operational step-by-step workflows of components in a system. An activity diagram shows the overall flow of control.

Employee



Customer

CLASS DIAGRAM

In software engineering, a class diagram in the Unified Modeling Language (UML) is a type of static structure diagram that describes the structure of a system by showing



the system's classes, their attributes, operations (or methods), and the relationships among the classes.

SEQUENCE DIAGRAM

Sequence diagrams are used to show how objects interact in a given situation. An

important characteristic of a sequence diagram is that time passes from top to bottom:



the interaction starts near the top of the diagram and ends at the bottom (i.e. Lower

equals later).A popular use for them is to document the dynamics in an object-

oriented system.

COMPONENT DIAGRAM

In the Unified Modeling Language, a component diagram depicts how components are wired together to form larger components and or software systems. They are used to illustrate the structure of arbitrarily complex systems



PACKAGE DIAGRAM

A package diagram in the Unified Modeling Language depicts the dependencies between the packagesthat make up a model. Package diagrams can use packages containing use cases to illustrate the functionality of a software system



DEPLOYMENT DIAGRAM

A deployment diagram in the Unified Modeling Language models the physical deployment of artifacts on nodes. To describe a web site, for example, a deployment diagram would show what hardware components ("nodes") exist (e.g., a web server, an application server, and a database server), what software components ("artifacts") run on each node (e.g., web application, database), and how the different pieces are connected.



STRUCTURE CHART

A Structure Chart (SC) in software engineering and organizational theory is a chart which shows the breakdown of a system to its lowest manageable levels. They are used in structured programming to arrange program modules into a tree.

CHAPTER 5

SYSTEM IMPLEMENTATION



SYSTEM IMPLEMENTATION

Computer will be used to maintain the records of the Mobile, Customer, sales

and purchase, in the computer database.

A Computerized report in a particular format can be generated.

Availability of Mobile can be checked.

Finding employee,customer,Mobile details is easier.

The details of the sales and purchasing of Mobiles will be recorded in the

system.



CHAPTER 6

FUTURE ENHANCEMENTS



FUTURE ENHANCEMENTS

The system could be modified suitably to work on a network. This involves, among other, resolving used conflicts, protecting database integrity and ensuring consistency of data if it is distributed across multiple locations.

Maintain attendance details of employee.

Maintain Mobile details.

Other possibilities



CHAPTER 7

CONCLUSION



CONCLUSION

An attempt is made in all its earnest towards the successful completion of the project. This system was verified with valid as well as with invalid data.

This system is user friendly since it has been developed in visual studio 8 a successful GUI environment. Since the connection can be extended to any database. The control will be more powerful.

Connecting it to any type of database extends the development control. Any suggestions for future development of the system are welcome

Upgrading the system if may can be done without affecting the proper functioning of system.
