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.
