E-Business Walmart Help

I’m having trouble with the following part of an assignment.

“Explain how e-business has affected Walmart’s business processes. Analyze the advantages, limitations, and risks of using or not using the Internet for business activities. Cite at least two sources.”

Your help is very much appreciated.

Thank you.
