research work paper

An complete research work paper written at professional level.

The research should be based on pros and cons of system architecture for company that has customer credit card information for both USA and Canada.

The topic should cover what are the legal government requirement for both USA and Canada, can USA and Canada customer credit card information be stored in same database or should it be different?

how should the architecture for this system be? what are the other companies doing to meet legal requirements.

It is safe to assume this will be a cloud based application. I need not more than 4 pages max but well researched with links to substantiate the research work.
