Case Study: Victorian Wine Growers Association.

The Victorian Wine Growers Association (VWGA) has many
shareholders. There are several kinds of shareholders within the association: Grower,
Employee and Private.Every shareholder
is registered and a record is created on the information system for them when
they first acquire shares.Registration
can be done in a number of ways: the shareholder goes into the head office or
completes a form and mails it to the head office. These details are then entered
by the office clerk; the shareholder phones or emails head office and their
details are entered by the office clerk, or; the shareholder enters their
details themselves via the company website.

The following details are entered for all shareholders,
regardless of how they register: name, postal address, contact telephone
numbers, email address, shareholder category, date joined and a unique
shareholder number. Grower shareholders require the following details: the name
of their property, the size of the property and a list of the wine varieties
that they produce. Employee shareholders have their job title recorded as well
as their office number and work telephone number.

All shareholders must agree to purchase shares through a
stock broker. Employee shareholders must use a particular stock broker company
as nominated for all employees by VWGA. Other shareholders may nominate a
specific stock broker company to purchase shares for them and details of this
company must then be recorded at the time of registration. Grower and private
shareholders may purchase from any broker and each broker may sell to any
shareholder. Employee shareholders must use a broker from the nominated company
only.

Each purchase of a parcel of shares occurs between a broker
and a shareholder and has the purchase date, the number of shares, the purchase
price per share, commission amount and the total amount recorded.Individual brokers are identified by their
broker registration code and have name and contact details stored along with
the details of their brokerage company name and postal address.

Information regarding all sales of shares and broker details
are recorded by an office clerk at VWGA.
Each shareholder is issued with a certificate of purchase each time they
purchase shares by an office clerk at VWGA.
Each certificate records a unique certificate number, the certificate
issue date, number of shares, purchaser’s name and broker’s name.

Given the current economic climate, shareholders may be
interested in monitoring the value of their current shares. Shareholders may
choose to receive regular email reports to keep track of current trade prices. Details
of these report requirements can be adjusted by the shareholder through the
company website. Shareholders select the frequency of these daily reports: 6am,
10am, 2pm, 6pm and 10pm or any combination of those times. Appropriate
reporting processes must be provided to manage the appropriate distribution of these
email reports to shareholders.

Dividend payments are automatically calculated by the system
for each shareholder on the anniversary of the purchase date of that particular
lot of shares.For each dividend, a
unique dividend sequence payment number is recorded as well as the dividend
date.The dividend amount to be paid is
set by a member of the board and updated to the system at the start of each
month.

Functionality to allow changes to any recorded information
must also be provided.

Modelling and Diagramming (100 marks in total)

Review the Victorian Wine Growers Association case study and
answer the following questions with reference to the information in the case
study.Do NOT extend the scope for any
of the following solutions beyond that specifically described in the case study
above.You are permitted to make
reasonable assumptions where necessary but these should be noted.

It is recommended that you review all documentation for this
case study before finalising any single solution. Ensure that the required
consistency has been included within and between each question solution.

Question 1:Event Table(30
marks)

Prepare an event table for the ‘Victorian Wine Growers
Association’ information system as described in the case study above.

Your event table solution should show at least the following
columns headings: Event, Event Type, Trigger, Source, Use Case, Response and
Destination.

Question 2:Domain Model Class Diagram(30
marks)

Prepare a Domain Model Class Diagram for the ‘Victorian Wine
Growers Association’ information system. This solution should show all classes needed
to support this information system as described in the case study above.All appropriate associations and multiplicity
should be included. Where appropriate generalisation/specialisation hierarchy
should be shown.

Solutions must follow the methodology as outlined within the
Satzinger et al textbook. Solutions are expected to show:

·
The class name and attributes list for each
class and sub class as required

·
All required associations

·
All attributes as specifically mentioned in the
case study must be reflected

·
Other attributes as needed to support the
described functionality.

It is not necessary to show methods, however you may include
them if you wish. Solutions are expected to align with the components as shown
in figure 5-38.

Question 3:Design Class Diagram(10
marks)

Prepare a Design class diagram for the Shareholder
and Shares classes ONLY. These two classes should be part of the Domain
model class diagram solution for the previous question.

Each of these design class diagrams are expected to have a
complete attributes list and a comprehensive methods list which supports the
specified functionality as described in the case study.

Solutions must follow the methodology as outlined within the
Satzinger et al textbook. Solutions are expected to align with the components
for the ‘Design class diagram for Student’ as shown on the right hand side of
figure 11-13.

Question 4:Use Case Diagram(20 marks)

Review your event table solution from question 1 to prepare
a Use Case diagram for the supporting information system.

Solutions must follow the methodology as outlined within the
Satzinger et al textbook. Solutions are expected to align with the components
as shown in figures 7-3 and 7-6.

Students may prefer to organise their solution by subsystems
if you feel that this is more suitable, similar to figure 7-5. The ACME use
case diagram solution provided as a resource on the course study desk outlines
an alternative but acceptable technique for ‘packaging’ use case diagrams.

Question 5:Use Case Description
(intermediate)(10
marks)

Prepare a Use Case intermediate description for the office
clerk ‘Creates Shareholder’ use case, as documented in the event table solution
and the use case diagram solution.

Solutions must follow the methodology as outlined within the
Satzinger et al textbook. Solutions are expected to align with the form as
shown in figure 5-14.
