Final answer:
The correct term for the process where detailed layers of data flow diagrams are created by expanding less detailed elements is called Data Decomposition. It is a process in which successive layers of data flow diagrams (DFDs) are constructed by 'exploding' the bubbles on a less detailed DFD to show more detailed data flows.
Step-by-step explanation:
The process in which successive layers of data flow diagrams (DFDs) are constructed by "exploding" the bubbles on a less detailed DFD to show more detailed data flows is called Data Decomposition. This technique allows for the breaking down of complex systems into smaller, more manageable components, making it easier to understand the system at various levels of detail.
By examining each component or "bubble" at a more granular level, one can better comprehend the interactions and data flows within the entire system.
