The Entertainment Zone video rental service. Illustrate your essay with specific examples.
This report is going to involve the study of a video rental
service and the name of the shop is The Entertainment Zone. Every
entertainment zone shop has one database assigned to it that cannot
be accessed from outside the store. The database contains
information on the customer's details and the stock levels. The
customer details include the following entities: Name, Address,
Telephone number, Membership number, and Credit Card detail. The
stock details include the following entities: Title, ex/rental, and
status, number of copies in stock, number of copies on loan, price,
and genre and age certification.
The system allows searches for customers on name or membership
number, and stock on part number and title. The system is used to
check out titles on customer accounts as well as checking them back
into the entertainment zone. If a customer requests, a title that
is not currently available, the store assistant can call another
store on the customer's behalf and check to see if that shop has
the request. This is very time consuming and a waste of resources.
The customer must also hold another account with the particular
store in order to rent a video from there.
SSADM would be the better method out of SSADM and Prototyping
for creating a new system for the entertainment zone. The reason
for this is that SSADM provides a structured analysis and design in
order to overcome the identified constraints. Then once the
analysis and design stages are complete, the implementation of the
system will occur in the video stores. Another reason that SSADM
would be a good choice is that SSADM is suited to large systems
where a database is primarily used.
A different methodology can be used to overcome the problem of
design and implementation because SSADM does not include ways in
which to implement a system. Prototyping can be used throughout the
implementation. Each individual area can be prototyped first before
full implementation of the system to the UK. This would be
beneficial as bugs will be present in the system and will need to
be fixed as they are spotted from prototyping, also operational
problems may occur after implementation and these will need to be
fixed before full integration to the UK.
