Plagiarism and Cheating
(Refer to section 8.7, page 6 of Seneca’s Academic Policy)
(or visit: http://cs.senecac.on.ca/bullets/cheating.html)
Your task is to create a database for Seneca’s Shear Salon. The narrative below explains the manner in
which this business is conducted:
Seneca's Shear Salon sells beauty products and provides hairdressing and other services
on a drop-in basis to customers who may be students, faculty, staff or the public.
Seneca’s Esthetics students provide the services and are supervised by faculty members.
A schedule is prepared each month identifying the faculty members and students
scheduled to work each day. Each day one faculty member is normally scheduled to
supervise students in the morning session and a different faculty member is scheduled to
supervise the afternoon session. Each day 5 students are scheduled to work in the salon.
Each student is assigned to a station: either the cash register, hair treatments, shampoo,
massage or esthetics. Students are assigned to work at different stations during the
schedule.
The services provided include: hair cuts, perms, highlights, manicures, pedicures and
massage. A list of services offered and charges is posted by the cash register.
A customer may have one or more services performed during their visit. A customer
may also purchase products sold at the salon. Information about products sold is posted
by the cash register.
After a customer is finished the student assigned to the cash register prepares an invoice
listing all services performed and the student who performed them as well as any
products purchased. Payment is accepted only in cash.
Requirements:
1. Prepare the physical database design (aka: data dictionary) that will guide you in the implementation
of your database. The eight (8) tables required for this task are given below
Table Name
Attributes

[ServiceCode, ServiceDesc, StationCode, Charge, Duration]
INVOICE
[Invoice#, ClientName, InvDate, HairEmpNo, MassEmpNo, EsthEmpNo,

[ProgYr, PayRate]
STATION
[StationCode, StationDesc.]
You will need one form for each table. (see below) -(i.e., 8 forms in all) You may copy the form below to
complete your data dictionary.
TABLE NAME: ______________________________

2a. Create the tables in the DB2 environment. Choose the account of one member of your group in
which the work will be done. Create a collection called Shearxxx (xxx stands for the account number; i.e.,
(B33) Create the tables including keys and constraints. The column names that you use in the creation of
this database should correspond to the names listed in the data dictionary. Note, at this point, you should
be working in the SQL environment and not in the *SYS environment. If you have not already done so,
use <Shift F1> to change session attributes. Coding will read as Shear.xxx
2b. Insert data into your created tables. The data that you will use comes from the userviews that
form the Appendix of this assignment.
Default
.
3. Data Manipulation.
With respect to the data stored in your tables, create 2 views.
a) The first view is called UnderanHour and should show the service description, charge and time
estimate for services that take less than 60 minutes.
b) The second view is called INV1423 and should allow the client to view the details of his November 1,
2001 visit.
c) Update the product table. Due to a company merger, the supplier Salon Products Ltd.has undergone a
name change and will now be known as Beauty Salon Products.
