1) Define entity type (the COLLECTION, universal object, not a single individual member) from the following:

- The entity concerned holiday trips (any one-time events, but NOT a specific one)

Follow the format of the entity type definitions on P.59 of the text, define the entity type [define ENTITY! Not define attributes]

2) Business rules, and attributes. From the following scenario:

TU.TOR has APPOINTMENT, STUDENT comes to APPOINTMENT

(All entities are in CAPS; 2) No attribute except keys (PK, FK); 3) All relationships are already given; please do NOT introduce your own relationship; in other words, ONLY depict what is explicitly given.)

For this scenario

1. Take the first entity type (1st entity only; not all three!!), identify all its relevant and practical attributes;
2. For the scenario, state ALL business rules.
