How are these data flows and the accompanying processing logic used in the system design phase of the life cycle? What happens when the data and data flows are modeled incorrectly? Be specific.
II. Imagine that you have just been hired by an organization and you have been tasked with purchasing 10 tablet computers. Compile a list of at least three criteria you will use to evaluate at least three alternatives using weighted multicriteria analysis. Make a purchase recommendation based on your analysis.
