1 CSC503 Exam 2 Name: Question 1 Assume that you have the following table: (AnimalID, VisitDate, OwnerID, AnimalName, OwnerName, AnimalDOB, OwnerPhone, Diagnosis, Cost, VetID, VetName) Assume that the following functional dependencies beyond that of the primary key are valid: AnimalID OwnerID, AnimalName, OwnerName, AnimalDOB, OwnerPhone OwnerID OwnerName, OwnerPhone VetID VetName Convert the table into 3NF. Put your answer on the test paper. It s already 1NF To 2NF (AnimalID, OwnerID, AnimalName,OwnerName, AnimalDOB, OwnerPhone) (AnimalID, VisitDate, VetID, VetName, Diagnosis, Cost) To 3NF (AnimalID, OwnerID, AnimalName, AnimalDOB) (OwnerID, OwnerName, OwnerPhone) (VetID, VetName) (AnimalID, VisitDate, VetID, Diagnosis, Cost)

2 Question 2 Use the file q2.sql for this question. me this file in a zip when you turn in your test. Modify the file q2.sql in the following ways: Change the Create Table commands so that primary keys are added to all tables. The primary key for Doctors is DoctorID, the primary key for Patients is PatientID, the primary key for Rooms is RoomID, the primary key for Wards is WardID, and the primary key for Assignments is RoomID and PatientID. Change the Create Table commands so that foreign key constraints are added to the tables. Note that DoctorMentorID must match another DoctorID in the Doctors table (though it could be NULL). Change the Create Table command for Rooms so that all Beds must be either 1 or 2. Change the Create Table command for Wards so that AvailableBeds must be less than or equal to TotalBeds. Change the Create Table command so that deleting a Rooms record will automatically delete all Assignments records with the same RoomID. Add a trigger so that whenever you add a new Rooms record, the value of TotalBeds in the Wards record with the same WardD will be increased by the number of Beds in the new record. Drop Table Assignments; Drop Table Wards; Drop Table Rooms; Drop Table Patients; Drop Table Doctors; Create Table Doctors( DoctorID Integer, DoctorName VARCHAR(20), DoctorPhone CHAR(12), DoctorSpecialty VARCHAR(20), DoctorMentorID Integer, PRIMARY KEY (DoctorID), FOREIGN KEY (DoctorMentorID) REFERENCES Doctors(DoctorID)); Create Table Patients( PatientID Integer, PatientName VARCHAR(20), PatientPhone CHAR(12), DoctorID Integer, PRIMARY KEY (PatientID), FOREIGN KEY (DoctorID) REFERENCES Doctors(DoctorID)); Create Table Rooms( RoomID Integer, WardID Integer, 2

3 RoomType VARCHAR(20), Beds Integer, PRIMARY KEY (RoomID), FOREIGN KEY (WardID) REFERENCES Wards(WardID), CHECK (Beds >= 1 AND Beds <= 2); Create Table Wards( WardID Integer, WardType VARCHAR(20), TotalBeds Integer, AvailableBeds Integer, PRIMARY KEY (WardID), CHECK (AvailableBeds <= TotalBeds)); Create Table Assignments( PatientID Integer, RoomID Integer, AssignDate Date, LeaveDate Date, PRIMARY KEY (RoomID, PatientID), FOREIGN KEY (RoomID) REFERENCES Rooms(RoomID) ON DELETE CASCADE, FOREIGN KEY (PatientID) REFERENCES Patients(PatientID)); create trigger addrooms after insert on Rooms for each row begin update Wards set TotalBeds = TotalBeds + :new.beds where RoomID = :new.roomid; end addrooms; 3

4 Question 3 Use the file q2.sql for this question. Write queries for each part. Put your answers on the test paper. A. Output the name and phone for all doctors with a specialty of either Surgery or Pathology. SELECT DoctorName, DoctorPhone FROM Doctors WHERE DoctorSpecialty = Surgery OR DoctorSpecialty = Pathology ; B. Output the number of doctors with the specialty of Surgeon. SELECT COUNT(*) FROM Doctors WHERE DoctorSpecialty = Surgery ; C. Output the number of rooms in each ward. SELECT WardID, COUNT(*) FROM Rooms GROUP BY WardID; D. Output the number of doctors in each specialty, but only include specialties with more than five doctors. SELECT COUNT(*), DoctorSpecialty FROM Doctors GROUP BY DoctorSpecialty HAVING COUNT(DoctorSpecialty) > 5; E. Output the name and phone numbers for all doctors and patients. SELECT DoctorName, DoctorPhone FROM Doctors UNION SELECT PatientName, PatientPhone FROM Patients; 4

5 F. Output the RoomID, WardID, and RoomType for all Rooms that do not have an Assignment. SELECT RoomID, WardID, RoomType FROM Rooms WHERE RoomID NOT IN (SELECT RoomID FROM Assignments); G. Output the names of all doctors and the name of their mentor. SELECT D1.DoctorName, D2.DoctorName FROM Doctors AS D1, Doctors AS D2 Where D1.MentorID = D2.DoctorID; H. Output the names of all patients and the name of their doctor. SELECT Patients.PatientName, Doctors.DoctorName FROM Patients INNER JOIN Doctors ON Doctors.DoctorID = Patients.DoctorID; I. Output the RoomID, WardID, RoomType, and the PatientID assigned to that that room. Output the room information even if no patient is assigned to that room. SELECT Rooms.RoomID, WardID, RoomType, PatientID FROM Rooms LEFT JOIN Assignments ON Assignments.RoomID = Rooms.RoomID; 5

6 Question 4 Use the file q4.xml for this question. Create a dtd file named q4.dtd that can be used to validate it. Make sure that you enforce primary and foreign key constraints defined in the attributes of the nodes. Include these files in your zip when you turn in this test. <!ELEMENT Data (Wards, Patients, Assignments)> <!ELEMENT Wards (Ward+)> <!ELEMENT Ward (WardID, WardType, TotalBeds, AvailableBeds, Room*)> <!ATTLIST Ward wardid ID #REQUIRED> <!ELEMENT Room (RoomID, Beds)> <!ATTLIST Room roomid ID #REQUIRED> <!ELEMENT Patients (Patient+)> <!ELEMENT Patient (PatientID, PatientName, PatientPhone)> <!ATTLIST Patient patid ID #REQUIRED> <!ELEMENT Assignments (Assignment+)> <!ELEMENT Assignment (PatientID, RoomID, AssignDate, LeaveDate)> <!ATTLIST Assignment patid IDREF #REQUIRED roomid IDREF #REQUIRED> <!ELEMENT WardID (#PCDATA)> <!ELEMENT WardType (#PCDATA)> <!ELEMENT TotalBeds (#PCDATA)> <!ELEMENT AvailableBeds (#PCDATA)> <!ELEMENT RoomID (#PCDATA)> <!ELEMENT Beds (#PCDATA)> <!ELEMENT PatientID (#PCDATA)> <!ELEMENT PatientName (#PCDATA)> <!ELEMENT PatientPhone (#PCDATA)> <!ELEMENT AssignDate (#PCDATA)> <!ELEMENT LeaveDate (#PCDATA)> 6

7 Question 5 Use the files q5.xml and q5.xsd for this question. Include these files in your zip when you turn in this test. Modify the file q5.xsd in the following ways: All patient phones should either be three digits, a dash, three digits, a dash and four digits; or three digits, a dash and four digits. All assign dates and leave dates are in The value of Beds should be either 1 or 2. WardType is Surgery, Medicine, Obstetrics, Pediatrics, or Psychiatry. Patient phones are optional. The WardID of Ward within Wards within Data is a key. The RoomID of Room within Ward within Wards within Data is a key. The PatientID of an Patient within Patients within Data is a key. The PatientID of an Assignment within Assignments within Data is a keyref that matches the relevant key. The RoomID of an Assignment within Assignments within Data is a keyref that matches the relevant key. <?xml version="1.0" encoding="utf-8"?> <xs:schema xmlns:xs=" <xs:element name="data"> <xs:element ref="wards"/> <xs:element ref="patients"/> <xs:element ref="assignments"/> <xs:key name="wardkey"> <xs:selector xpath="wards/ward"/> <xs:field xpath="wardid"/> </xs:key> <xs:key name="patientkey"> <xs:selector xpath="patients/patient"/> <xs:field xpath="patientid"/> </xs:key> <xs:keyref name="patfk" refer="patientkey"> <xs:selector xpath="assignments/assignment"/> <xs:field xpath="patientid"/> </xs:keyref> <xs:key name="roomkey"> <xs:selector xpath="wards/ward/room"/> <xs:field xpath="roomid"/> </xs:key> <xs:keyref name="roomfk" refer="roomkey"> <xs:selector xpath="assignments/assignment"/> 7
