Question

2. The following is the relation notation of a table for a veterinary office. [70 pts. total] VETERINARY_OFFICE (PetID, PetName, PetType, PetBreed, OwnerID, OwnerLastName, OwnerFirstName, ServiceDescription, ServiceDate, ServiceCharge) The functional dependencies are given below: PetID -> PetName, PetType, PetBreed, OwnerID, OwnerLastName, OwnerFirstName OwnerID -> OwnerLastName, OwnerFirstName ServiceDescription -> ServiceCharge PetID, ServiceDate > ServiceDescription, ServiceCharge

Assumptions: 1)A pet belongs to only one owner,

2) an owner may have more than one pet,

3A pet receives at most one treatment on any given date. Use the functional dependencies above to answer the following three questions.

Use relational notation for all relations in your answers.

(Note: do not make additional assumptions and functional dependencies)

Note: Not following relational notation is subject to 10 points off. Not including dependencies and references are subject to 10 and 5 points off, respectively. Solutions without detail steps or intermediate steps may be subject to penalties up to 50% off.

2.1. Show the 1NF in relational notation (indicate the primary key).

2.2. Identify and list all partial dependency in the relation only (if any) and identify and show the 2NF. Use relational notation and show the partial dependencies, all relations and their references.

2.3. Identify and show all transitive dependencies (if any) in your answer to question 2.2. Identify and show 3NF (show all relations). Use relational notation. You need to show the transitive dependencies and all relations and their references.
