Chapter 4: Organisations and information needs
Charlotte Town has two small recreation centres. One of the centres has a
swimming pool, which the two centres share. The two centres are considering
sharing some of their other facilities, such as the aerobics area and the tennis
courts. Some recreation personnel work at both centres and some members
attend both. A communications link has been planned to connect the two
information systems together.
a What would be one of the organisational goals of the recreational centres in
To ensure that both recreational centres share information on memberships.
To ensure a high utilisation rate of shared areas such as aerobics and tennis courts.
b Both recreation centres have decided to establish a common customer
information system. State what data items would allow the recreation centres to
uniquely identify each member.
The information system should allow for a unique ‘Member ID’ across both
recreation centres. (Revision of database unit.)
Provide two examples of data, other than personal details, that the two
recreation centres may wish to share.
How often a member visits.
What facilities they routinely use.
A school has been allowing unlimited access to the Internet for students. Their
Internet service provider has recently sent a $35 000 bill for the past six months.
The school had budgeted for only $1000 per month and instituted a policy that
students should pay for their use of the Internet. When trying to implement the
policy, the school discovered that there were no records of who had accessed
which sites and how much material had been downloaded.
What is the problem? What category of problem does this fit into?
The problem is that the school has kept incomplete records of how much data
students have downloaded on their school intranet account.
b The school has now decided to introduce login names for Internet access and to
maintain log files of who visits which sites and how much each person
downloads each day. Are these log files data or information? Why?
The log files are data, what the school does with the data to create meaning or
make decisions is information.
