Brief
Arthur Pendragon is President of the Camelot Chivalry Club. Most of the Club members
live in Camelot.
Arthur would like the records of the chivalry club computerised into a database
displaying the information in an appropriate format that is legible and easy to read. A
handwritten copy containing the membership data has been supplied.
You are to plan, create and evaluate a database using appropriate field sizes, types and
formats to display the club members’ information. Because Arthur may want to create
envelopes from the database in the future, please format the Town/City field to capital
letters.
Arthur wants to be able to view a complete list of members’ details and other selected
data from the database as required. He will want to print out the database viewed in
different ways (eg arranged by Number or Last Name).
Arthur will also want you to use the database to:
a. edit records in the table (add, update, and delete) and reprint the table
b. query (filter) the database to produce only specified information
i.
members’ data only (no scores)
ii. only male members’ names and addresses
iii. members names and scores only
iv. details of members with certain surnames only eg Tuck or Hood
c. sort the table/query on a specified field
d. print the table/query.
e. report on the tournament results
Part A:
Plan your database. (PC 1.1, 1.2, 1.3)
Instructions:
Using the planning template on the back of the assignment cover sheet, create a plan for
making the database to meet Arthur’s requirements. It should include:
a statement of the purpose of the database;
a list of the steps you are going to take in order to complete the project;
a reason for the model of database you have selected to use;
the design of the features required in order to provide solutions to the requirements listed in the
brief:
the table or tables required;
the properties of the data fields;
queries that you will need to create; and any
printed reports required.
Ongoing planning should be recorded as annotations to your draft printouts. You should
include explanations for any changes made in your resource allocations (including time)
or any design alterations or refinements.
