We are living in an information era (i.e. information economy). Information systems are changing the way in which
companies conduct their activities.
Business involves the processing and exchange of information. Therefore, data/ information can be considered as a
valuable asset.
The aim behind knowledge is essentially to create competitive companies, manage global markets, add business value,
and provide useful products and services to customers.
Acknowledging the potential of information systems and having the ability to put this knowledge to work can not only
result in a successful personal career, but can also contribute to companies reaching their goals and for people to maintain
a high quality of life.
You must examine :
● different forms of information,
● the way information is produced through different systems
● and the reason why businesses needs information.
Inputs relate to information being supplied into the system
Output relates in information supplied out of the system.
