Tipping Outdoor Getaway Adventures (TOGA) runs holiday travel
adventures throughout South America.
The adventures originate in Melbourne and go to places such as
Peru, Brazil and Argentina. Each adventure is offered on a number
of separate occasions. Each adventure has an adventure code, a
description and a duration (number of days).
Each time an adventure is scheduled to run, TOGA record the tour
date, and the tour price. No two tours for the same adventure code
commence on the same date.
People interested in participating in an adventure usually ring
or email TOGA
For each customer who books a tour, TOGA assigns the person a
customer identification code and records the person's name, address
and phone number. TOGA also records the total payment(s) that have
been made by the customer for the tour. (A customer may make a
number of partial payments). For each payment, the amount and the
payment date is recorded. Customers cannot make bookings or
payments on behalf of other people on the tour. (For this
assignment, consider a family of four people as 4 individual
customers.
For each tour TOGA offers a number of Activities to prepare for
the adventure. Activities may include fishing, swimming, kayaking,
Rock Climbing, Toga Party, etc. Each activity has an activity code
and an activity description. TOGA administrators specify which
activities are available for each tour (e.g. this will change from
tour to tour depending upon weather conditions, access to
resources, time of year etc
TOGA records which tour activities each booked customer has a
preference for (customers are encouraged to nominate for more than
one activity in case one or more activities are cancelled due to
unforeseen circumstances). Obviously customers can only choose
activities that are available for the tour that they have
selected.
