INTRODUCTION
To those of you, who wish to enrich your minds, welcome to the AIN1501 module! As
Ford said, "Anyone who stops learning is old, whether twenty or eighty. Anyone who
keeps learning today is young. The greatest thing in life is to keep your mind young."
Please note that the successful completion of this module will not make you a
computer specialist; rather, it will ensure that you have a good background knowledge
of accounting systems in a computer environment. You will be able to use this
background knowledge in your studies, whether you wish to become an accountant,
an auditor, or a business specialist. This module is therefore a basic but important
