Using a UML application like Visio (or a free version) create a data flow diagram of what happens when a customer buys an item in an e-commerce system. Make sure you think through all of the potential data elements involved. Try to make the most detailed and realistic DFD that you can. Paste an image of the DFD into a word document and submit.
*******Note, there is no turnitin or plagiarism check for this as you are creating a DFD. Do not copy one that you find online, make sure you are building your own diagram from scratch.
