Know-How Exchange : Student Questions

This sounds like a homework assignment, so I am moving it to the Student category.

Have you visited the Important Guidelines page? Please go there and read everything, especially ITEM FIVE. It might help you understand how to reframe your question, which you can do by adding your own comments to this thread.

Sorry if this sounds rude, but we don't appreciate it when students dump their assignments here. Your professors aren't too thrilled about it, either.

"i am a student and i have to hand in a essay for information management in e-commerce"

Well, then, you really should start writing! That's a lot of work!
