Information Systems

 

Definition of an Information System:

 “Information systems are computer systems that support end users, giving them access to the information. For a large number of systems the information is held in databases and access is via database management systems. Information systems perform a variety of tasks. While all of the information processes are represented in information systems, the emphasis in this topic is on the processes or organising, storing and retrieving with database systems and hypermedia.” Page 35 of IPT HSC Syllabus, 1999.
