software use

I currently work at Publix and have been there the last 4 1/2 years. It was my first job and probably my last, I plan on making a career out it. I work at the customer service counter and really the only thing I have to use a computer for is e-mail use. However, we do have a software that stores all of the information that we do in one day on an ISP tape. The stock clerks also use handle helds to scan invetory and do counts. I really do not have to use any software for the job I do. All I really deal with is money.
