EXAMPLE CASE STUDY
LSBU Outward Bound
LSBU runs an Outward Bound Centre based in the Lake District wishes to build a
database to store and manage information about its business. The Outward Bound
Centre takes bookings from clients for adventure holidays and team building events.
Clients are organisations such as schools, youth groups and businesses. Information
stored about clients includes their unique client number, the client’s name (School
name, business name, etc.), and the name and contact details of the person
representing the client organisation.
The centre has a number of accommodation options: a four star hotel; a hostel with
large dormitories for children and smaller shared rooms for supervising adults; and a
small camping ground. The name and type of these options is stored, along with the
total number of people they can accommodate.
Each booking has a unique booking number, the date that booking was made, and
the dates of the stay. When making a booking, clients state how many people will
be staying, and what type of accommodation is required. They also say whether
they will use the restaurant or self-catering facilities. The booking will also include
any additional facilities required by the client.
The centre contains a number of additional facilities for hire. These include lecture
theatres, teaching rooms and computing labs with Internet access. Portable multimedia projection and presentation equipment are also available for hire.
There are various outdoor pursuits facilities including: obstacle course, climbing-wall
with safety equipment, paintball-wargames, canoes, hill walking... etc. Details of
these various facilities, including any hire charges, need to be stored on the
database. During any booking, the client may use these facilities. The date when a
facility is booked for use must be recorded.
Use of outdoor pursuit facilities is supervised by one or more trained members of
staff. Staff may be trained to supervise more than one outdoor pursuit facility. Each
member of staff has a unique staff number, and their name and contract details (full
or part time) are also recorded

MARKING SCHEME AND TASKS
Complete ALL tasks listed below.
Every task requires a supporting narrative (max: half a side A4 per task)

4
TASK
Using UML notation draw a complete Entity Relationship
Diagram for the case study. Include a complete list of all
entities and their attributes including all primary/foreign
keys as part of your answer. (Consider carefully the
attributes required to complete task 4 when you are
choosing appropriate attributes).
Draw a complete set of functional Dependency Diagrams
for the case study to prove that all of the attributes within
your entities are in BCNF
Using suitable relational database software (either: Oracle
10g / 11g), Write SQL & PL/SQL scripts to set-up all tables
including your own, well-designed test data (minimum 5
records per table), to implement your entity model as a
database. Provide printouts of all SQL creation
statements, also the sample tables & data.
Set-up and test all of the following tasks using Structured
Query Language (SQL) or Procedural Langauge SQL
(PL/SQL). You must provide printouts of all SQL and
PL/SQL for each task AND the task output:
a) Write a query to find which Customer has made
the most bookings in the last 6 last months
b) Write a query to find what is the average age of
staff who are assigned to work on the outdoor
pursuits
c) Write a query to produce a list of all customers
who have rented self-catering accommodation in
the past year.
d) Write a stored procedure to calculate a final bill
for a given customer who has used various
facilities during their stay
e) Write a stored procedure to provide a monthly
report showing the total revenue raised by each
outdoor pursuit
