In addition to these you should also consider learning how to work within a database program. Microsoft Office Professional Suite is the most commonly used because it comes packaged with most business systems, and also because of the great amount of documentation that is available about how to use it. I use the Office 2000 Professional Suite because it has all of the buttons and whistles that I like in one integrated package, but I have also seen the Corel WordPerfect Suite 8 used in some smaller businesses.
