In 500 words or more, explain PCI compliance to the database administrator at a large retailer. Consider the consequences for non-compliance. 

Cite your sources. Do not copy. Write in essay format not in bulleted, numbered or other list format. 

It is important that you use your own words, that you cite your sources, that you comply with the instructions regarding length of your post and that you reply to two classmates in a substantive way (not ‘nice post’ or the like).  Your goal is to help your colleagues write better. Do not use spinbot or other word replacement software. It usually results in nonsense and is not a good way to learn anything. Please do not use attachments unless requested.
