Part B
Compare and contrast the structured analysis and design approach with other modelling techniques (e.g., the object-oriented approach), and clearly identify the strengths and weaknesses of each approach. Your justification should be supported by appropriate references.
VCI has outsourced a Credit Agency to perform credit checks on prospective guardians. Obviously, VCI will not perform credit checks on VCI employees that are also signing up as guardians. VCI will contact this credit agency once they have collected the Guardian’s general information and payment information and the member’s information. Upon receiving the credit report from the agency, the Park Ranger will update the guardian and member’s VCI Park status from pending to active.
A child whose guardian enrols them in VCI is called a member and receives an entrance pass (user id and password) upon credit approval of the guardian. The entrance pass is validated every time the member enters the VCI premises through VCI’s web page. Once inside the premises, the member can visit any or all park services for which their guardian has signed them up.
University function provides the member with a distance learning classes and receive certificates or credits.
Guardian Services
Enter new or change existing criteria for member admittance to VCI Park or individual park services.
Since VCI is a new company, we are planning to expand their park services within one to two years depending upon guardian membership. The VCI Marketing staff is also planning to have special park deals throughout the year. These special deals include special park service pricing for a specific period of time.
Did you do your chores for today? (yes/no)
What grade did you receive on your science test? (the guardian may customize this question by entering any subject for the test).
The number of minutes the guardian will allocate as bonus time (if good response received) or deduct from a park service (if a poor response received).
The park in which bonus time is allocated or from which time is deducted.
Membership Terms and Conditions
Guardians can only sign up children as members between the ages of 10 and 15 years old. There is a monthly fee for the VCI service per child/member. In addition, there is an hourly fee for each park service. The park fee is charged in minimum blocks of 15 minutes. There is a 15% discount for each additional member a guardian signs up for membership. This discount is given on the charges for each member other than the one with the highest charge for the month.
There are several payment methods the guardian can choose to pay their account. They can provide VCI with credit card information or checking account information in order for VCI to charge their desired account for the invoice amount automatically each month. Another payment option is for the guardian to pre-pay, which means that the guardian sends in funds which are depleted as the members use the park services, and if it becomes completely depleted, the members are not allowed to continue using the park system. The guardian may set a threshold at which he/she would like to be notified so that he/she can replenish the account. If the pre-payment option was chosen, VCI will notify the member via an online message when they near the depletion of the account (15 minutes left??). Another payment option is to send in a check, money order, or individual credit card authorization each month upon receipt of the VCI invoice.
Guardians with poor credit ratings and guardians whose accounts have an open balance for three months will be required by VCI to pre-pay.

Also when an Invoice Item row is created, the TotalFee on that row is added to the TotalFee on the matching Member Summary row.
When a Member Summary row is created, if there is not yet a matching Invoice row (for that month for that guardian) one is created and the first two attributes shown are copied to the new Invoice row.
