Final answer:
An analyst can create clear and uncluttered data flow diagrams by representing processes as black boxes, which show inputs, outputs, and functions while omitting internal details.
Step-by-step explanation:
By showing processes as black boxes, an analyst can create data flow diagrams (DFDs) that show how the system functions but avoid unnecessary detail and clutter.
In DFDs,a black box represents a process or function, where the input, output, and general function are known, but the internal workings are not shown.
This simplification helps analysts to focus on the flow of data rather than the intricacies of how each process is implemented, promoting clarity in the understanding of the overall system's data processing.
