In this assignment, you are required to design and implement a database system for a given scenario,
applying the methodologies and technologies that you learn from the unit.
Scenario
Suppose that the director of the University Accommodation Office want to have a database designed
and developed to assist with the administration of the office. The requirements collection and analysis
phase of the database design process has provided the following data requirements specification for the
University Accommodation Office database followed by examples of query transactions that should be
supported by the database.
Data Requirements
Students
The data stored for each full-time student includes: the banner number, name (first and last name),
home address (street, city, postcode), mobile phone number, email, date of birth, gender, category of
student (for example, first-year undergraduate, postgraduate), nationality, special needs, any additional
comments, current status (placed/waiting), major, and minor.
The student information stored relates to those currently renting a room and those on the waiting list.
Students may rent a room in a hall of residence or student apartment.
When a student joins the university, he or she is assigned to a member of staff who acts as his or her
Adviser. The Adviser is responsible for monitoring the student’s welfare and academic progression
throughout his or her time at the university. The data held on a student’s Adviser includes full name,
position, name of department, internal telephone number, email, and room number.
Halls of residence
Each hall of residence has a name, address, telephone number, and a hall manager, who supervises the
operation of the hall. The halls provide only single rooms, which have a room number, place number,
and monthly rent rate. The place number uniquely identifies each room in all halls controlled by the
Residence Office and is used when renting a room to a student.
Student flats
The Residence Office also offers student apartments. These are fully furnished and provide single-room
accommodation for groups of three, four, or five students. The information held on student apartments
includes an apartment number, address, and the number of single bedrooms available in each
apartment. The flat number uniquely identifies each apartment.
Each bedroom in an apartment has a monthly rent rate, room number, and a place number. The place
number uniquely identifies each room available in all student apartments and is used when renting a
room to a student.
Leases
A student may rent a room in a hall or student apartment for various periods of time. New lease
agreements are negotiated at the start of each academic year, with a minimum rental period of one
semester and a maximum rental period of one year, which includes semesters 1 and 2 and the summer
semester. Each individual lease agreement between a student and the Residence Office is uniquely
identified using a lease number.
The data stored on each lease includes the lease number, duration of the lease (given as semesters),
student’s name and banner number, place number, room number, address details of the hall or student
apartment, and the date the student wishes to enter the room, and the date the student wishes to leave
the room (if known).
Invoices
At the start of each semester, each student is sent an invoice for the following rental period. Each
invoice has a unique invoice number. The data stored on each invoice includes the invoice number, lease
number, semester, payment due, student’s full name and banner number, place number, room number,
and the address of the hall or apartment. Additional data is also held regarding the payment of the
invoice and includes the date the invoice was paid, the method of payment (check, cash, Visa, and so
on), the date the first and second reminder was sent (if necessary).
Student apartment inspections
Student apartments are inspected by staff on a regular basis to ensure that the accommodation is well
maintained. The information recorded for each inspection is the name of the member of staff who
carried out the inspection, the date of inspection, an indication of whether the property was found to be
in a satisfactory condition (yes or no), and any additional comments.
Residence staff
Some information is also held on members of staff of the Residence Office and includes the staff
number, name (first and last name), email, home address (street, city, postcode), date of birth, gender,
position (for example, Hall Manager, Administrative Assistant, Cleaner) and location (for example,
Residence Office or Hall).
Courses
The Residence Office also stores a limited amount of information on the courses offered by the
university, including the course number, course title (including year), course instructor, instructor’s oncampus
telephone number, email, room number, and department name. Each student is also associated
with a single programme of studies.
Next-of-kin
Whenever possible, information on a student’s next-of-kin is stored, which includes the name,
relationship, address (street, city, postcode), and contact telephone number.
Query Transactions
Listed here are some examples of query transactions that should be supported by the University
Accommodation Office database system:
(a) Present a report listing the Manager’s name and telephone number for each hall of residence.
(b) Present a report listing the names and banner numbers of students with the details of their
lease agreements.
(c) Display the details of lease agreements that include the summer semester.
(d) Display the details of the total rent paid by a given student.
(e) Present a report on students who have not paid their invoices by a given date.
(f) Display the details of apartment inspections where the property was found to be in an
unsatisfactory condition.
(g) Present a report of the names and banner numbers of students with their room number and
place number in a particular hall of residence.
(h) Present a report listing the details of all students currently on the waiting list for
accommodation; that is; who were not placed.
(i) Display the total number of students in each student category.
(j) Present a report of the names and banner numbers for all students who have not supplied
details of their next-of-kin.
(k) Display the name and internal telephone number of the Adviser for a particular student.
(l) Display the minimum, maximum, and average monthly rent for rooms in residence halls.
(m) Display the total number of places in each residence hall.
(n) Display the staff number, name, age, and current location of all members of the residence staff
who are over 60 years old today.
Your tasks
In the assignment, you are required to accomplish the following tasks:
Task 1: Conceptual data model (5 marks)
Create a conceptual data model for the University Accommodation Office scenario. State any
assumptions necessary to support your design. Check that the conceptual data model supports the
required transactions.
Task 2: Logical data model (5 marks)
Create and validate a logical data model from the conceptual data model for the University
Accommodation Office scenario created in Task 1.
Task 3: Physical database design (5 marks)
Based on the logical data model developed in Task 2, create a physical database design for the University
Accommodation Office scenario based on the DBMS that you have access to.
Note: You can choose whatever DBMS (e.g., Microsoft SQL Server and MySQL) you feel comfortable and
confident to use, as long as you are able to implement the University Accommodation Office database
with the DBMS.
Task 4: Implementation (5 marks)
Implement the University Accommodation Office database using the physical design created in Task 3.
Task 5: Query transactions (5 marks)
Create the SQL statements to implement the query transactions (a) to (n) listed in the University
Accommodation Office scenario. Apply these transactions into the University Accommodation Office
database created in Task 4.
Submission requirements
