Consider top-down-iterative refinement and dynamic dataflow analysis in detail as design techniques. state the most significant aspect or aspects of both design techniques which make them different. what characteristics would you expect the designs produced by these techniques to have in common for the same problem and why? is top-down-iterative refinement or dynamic data flow analysis a more effective tool to elicit specifications and the user explain the current process in an existing system utilized by the customer to complete their work? explain why your choice is true. you must convenience me you have mastered the design concepts.
