Acknowledgement

We would like to thank our lecturer Ms. Nadeera Ahangama, without her continuous

guidance and assistance we wouldn’t have been able to get anywhere close to what we

have done in this project. She also made it through her very busy schedule just to help us

with our problems that we faced while developing this program and for that we are very

thankful to her.

Also, our gratitude goes to APIIT Lanka (PVT) Ltd for providing the necessary library

facilities which we used a lot to complete this project and also the computer laboratories.

Finally we would extend our thankfulness to our batch mates of DF0931ICT for their

help with even the smallest problems that we encountered while working on this project.

Last but not least we are indeed grateful to all our friends stood by us helping in various

ways.

Introduction

Our assignment topic was to develop software for a VCD rental shop, where the entire

system is computerized to allow burrowing, returning modifying, updating and many

other new features which accommodate with regard to this kind of system.

We developed this project by using the software Visual Basic. NET for the coding and

also the designing of the interface, this was aided with the software Microsoft SQL

Server where we used this as our database to store and retrieve the data from.

The system is designed so that it will appear first with a splash screen, also known as a

welcome screen, which then moves on to a login screen where the username and the

password has to be entered in order to differentiate between the operator, administrator

and the customer. This is done so that these different users have restricted access to the

system.

A customer has the privileges only to view:

To view his or her details and the VCDs that are available at the rental store

The operator has the access to the following items:

The customer details and also the VCD details in order to operate the

transactions taking place in the rental store.

In addition to the above items, of both the customer and the operator, the administrator

has the privileges to the following:

The administrator has all the writes, when we take a look at all the other two

groups. The administrator has the privileges to add, delete and modify

customer’s details and the VCD details.

Project Description

1.1 Functionality of the project

This is a system that is developed for a VCD rental shop that keeps track of the VCDs

that are being rented, the customers that borrow the VCDs and the transactions that take

place. This system is handled by the shop keeper, who is the operator in our case. The

administrator is the head of this business and has all the privileges that are provided with

the software. Like the deletion of customer details, modifications and also addition of

new customers, these can only be done by the administrator. The operator has access to

all the details of the customers and also the VCD details but doesn’t have the privilege to

change any of the information. The customer also has been given an interface to deal

with, where the customer has only the privilege of viewing details such as his or her

account details or search for the available VCDs available at the store.

These three categories are being differentiated when it comes to the login screen where

the administrator has to enter their unique username and password and they will be taken

to the administrator form. If the username and password matches that of the operator

then the operator form will be displayed, and if the customer enters his or her username

and password the customer form will be displayed.

The fine and all the dates of when the customer joined and when a VCD was borrowed

has been programmed to be auto generated so that the user wouldn’t make any mistakes

and the chance of errors will also reduce, which means that the program will be having a

good error handling system. The fine will be added if the user has rented the VCD for

more than three days.

6.0 Limitation

When compiled to an “.exe” format the program would not run on Mac machines

since they use a different operating system when compared to the normal

windows operating system.

The password that is given when the person registers to the system has to be used

and cannot be changed.

24 | P a g e

7.0 Further Development

The further developments that we would like to have added were mainly the new

features, which are like:

Uploading of images and trailers of a particular movie that has been recently

added.

The system should have the option of generating reports as graphs so that it

would be easier to understand and also more user friendly rather than having

only to look at lists of data.

Allow the user, operator or the administrator to change their password since they

are given one and they have to keep on using that.

Provide a help function so that it would be easier to get help at that moment

instead of asking the operator help.

Conclusion

Visual Basic.NET is user friendly software whose abilities were clearly seen in our

project. It gave us a hand on experience about the software, what it is used for and how

it can be applied to a day to day situation.

The project which was carried out with the purpose of designing a computerized system

for a VCD rental shop, developing it and implementing it successfully was the main

objective of this whole process. This documentation was a guide to all the readers, the

viewers who are interested in using the system for evaluating the project or trying to get

an idea how to carry out the similar projects in the future.

This documentation is carried out according to the requirements highlighted and

discussed in the meetings. The system is successful in terms of interface design and the

functionalities.

The Learning that was Gain carrying out this project was achieved while developing and

coding, implementing. Each member gained the experience about visual basic.net as

they are coding, according to the project requirements given in the description.

Critically evaluating the system it is user friendly and with providing the basic aspects

highlighted in the project description.
