Large retail organisations employ a wide variety of computer-based information systems in order to support their activities. Considering a large supermarket chain, such as Sainsbury’s, you are required to:

(a) define the term ‘computer-based information system’;

(b) identify the types of computer-based information systems that are likely to be found within a typical branch. Your response should describe the function of each system identified and the category to which it belongs.

(c) selecting one of the systems identified in (a), describe the system in more detail, identifying the hardware, software, data and people resources it employs.
