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.
