Executive Overview
The Hotspot Enta (HES) system will be a global Web-based marketplace bringing together private
individuals and small companies to buy and rent movies and video games. It will take advantage of the
Internet and World Wide Web to radically improve the way they buy and rent items.

The customer objectives for the HES are to:

 Provide them with a huge selection of items (and sellers).
 Enable them to easily search for, find, and buy the items they want.
 Enable them to buy items that they could not ordinarily find or afford.
 Enable them to help set (and thereby minimize) the price of the items they wish to buy (e.g., via
promotions).
 Make buying more convenient by allowing them to buy items:
 Anytime (i.e., 24 hours a day and 7 days a week).
 Anywhere that the buyers have access to the Internet (e.g., at home, at work, and while
traveling).
 Minimize risks associated with buying over the Internet.

The seller objectives for the HES are to:

 Provide them with a huge customer base of potential buyers.
 Enable them to easily target and personalize their marketing to appropriate potential buyers.
 Enable them to sell items that they could not otherwise afford to sell (e.g., by minimizing their
overhead and transaction costs).
 Enable them to determine the market price of their items and set their prices accordingly (e.g., via
auctions or direct sales).
 Make selling more convenient by allowing them to sell items:
 Anytime (i.e., 24 hours a day and 7 days a week).
 Anywhere the sellers have access to the Internet (e.g., at home, at work, while traveling).
 Minimize risks associated with selling over the Internet.

The HESC objectives for the HES are to:

 Minimize the costs of providing a marketplace (e.g., capital costs, labor costs) compared to a
physical marketplace (e.g., a shopping mall) by maximizing automation and thus minimizing
labor and facilities costs.
 Maximize income by maximizing the number of sellers (i.e., movie production houses) paying
marketplace fees.

INTRODUCTION

The video rental industry is an ever evolving industry that changes with the economy, evolution of culture
and technology ant to remain viable in the business, the clients must be willing to evolve. The aid of the
computer and a system that is fully computerized, user- friendly, time efficient and well organized, is
indeed very useful in realizing this quest.

BACKGROUND AND OVERVIEW

A growing video store business called “Hotspot Enta” is looking to expand its chain of stores and when
the business was started the client did not account for such rapid growth in the market place. As a result
the existing software will not scale of perform to the expectations of its business needs.

“Hotspot Enta” requires an online software system that will manage all aspects of rental, sales, customers
and inventory. They require that this information be stored in a central repository and can be updated, and
accessed from any of its stores.

When a new customer visits the system he should be able to watch movie trailers and their reviews and
ratings, search movies and browse through some categories. However, in order to rent a movie he has to
subscribe for a membership. The customer should be able to receive the movie by post. In addition, the
customer should be able to see his rental history and also receive an email newsletter from the system,
containing news about movies and new DVD releases.

STEPS

The above scenario is briefly shown in the following steps:

1. Customer subscribes for membership by providing personal information and credit/debit card
information.
2. Customer browses the product and can add a movie to be rented into a wish list.
3. The movie will receive the movie by post.
4. After watching, the customer can send it back.
5. After receiving it the system will send another movie from the wish list.

The following stakeholders are identified in our online rental system:

1. Customer-A person who subscribes for a membership in order to rent DVD.
2. Employee-Who here is Hotspot Enta, who offers the rental services.
3. DVD Store-Where the DVD is housed to be sold or rented.
4. Post Office-A post office that provides delivery services.
5. Financial Institutional-Bank or Credit card companies that provide financial services to customer
or DVD store.
6. Supplier-A wholesaler that supplies DVDs/cassettes to the DVD store.

Some of the problems that this customer currently has as a result of its existing software solution, apart
from the obvious that it hinders their plant to expand are;

1. No central repository where information can be accessed easily and quickly
2. Manually updating a central database on a weekly basis will tie up a resource for hours per
week at least.
3. The response times of the current software solution is at a critical poor level. Often customers
are left standing at the counter with a clerk while the clerk waits for the customer information
to appear on the screen.

Some of the tasks we will engage in during this project are as follows;

 Become familiar with the current system.
 Develop supplementary specifications.
 Examine all function requirements.
 Develop vision.
 Bring forth stake-holder requests.
 Structure.
 Come up with new system.

AIMS AND OBJECTIVES

By implementing our system, the owner will have a competitive advantage over other video stores and a
greater overall productivity in terms of sale. Our proposed video rental system aims at achieving the
following:

1. Developing a new system better than the current system.

2. Manage to build-up a friendly environment to customers.

3. Enlarge the marketing of video rental to near-by towns.

4. To create a movie rental store whose goal is to exceed customer expectations.

The primary objective of this project is to address the common problems which a video rental system
experiences. The objectives include:

- Ensuring that the rental system is in the real time performance

- Increase the number of customer by 5% by the end of the year

RESOURCES

In order to achieve coming up with a new system we’ll need the following resources;

1) A Computer.
2) SQL Server for data storage.
3) Programming language like Visual Studio 2010 for developing the software.

CONSTRAINTS

The constraints define the boundaries of the work, which may include resources, budget and any
standards to be adhered to. The main challenges that would/might be experienced may include:

1. If the central repository crashes all data and information will be lost.
2. Access right is limited only to a few.
3. The storage memory for the database is limited.

FEATURES

There are various advantageous features of the online video rental system and some of them are given
below:

1. Account and invoicing management.
2. Inventory management.
3. Track transaction history and user profiles.
4. Facility to import old data.
5. Customize reports generation and printing facility.
6. Easily customizable system.

All these features will make it very simple to run the video store. The effective proceeding will increase
the chances of getting new business. The online rental system will provide the users a very unique
browsing experience. In just a single click the user can discover the recommended movies and the
reviews about the particular movie in seconds. The user is given various admin rights where he/she can
change the priority the movies to be delivered to him. Another advantageous feature is that the user can
make payment through their credit cards as well.

Functional specification

proposed system. In addition this document further explain the sub functions of the system such
as customer registration, purchase movie, Sell a movie, Rent a movie, Return. Etc.

REFERENCES

Systems similar to DRSMS are being used by most establishments in the DVD rental/sales
industry. One of our team members has had experience with Inventory Management, and all of
our team members have experience with software development for work and school. We will
draw on this experience to produce a system that is more user-friendly and intuitive than the
average software available to DVD rental stores.

REQUIREMENTS ANALYSIS

Introduction:

When we consider about software development projects, requirement analysis is a most
important part. In this part, one is able to collect information's together about current situations in
order to identify the drawbacks about the system. This requirement analysis should be correct,
testable and relevant to the company requirements. Moreover, it must be significant to system
designing part.

Requirements Gathering

In this part requirements can be collected in to the system boundary by contacting the users to
find out their requirements. In this part we’ve used different types of techniques such as
interviews, questionnaires, observation, etc... to gather information.

A. Questionnaires

Questionnaires are quick gather information from large amount of people in a certain period. It is
possible to do paper based document either electronic copy. In addition, it is very cost effective
method when compared with interviewing. Major advantages are most of the people are familiar
to questionnaires and they are very easy to analyze.

This questionnaire has been used to gather information.
