To avoid unnecessary detail in a DFD, processes are represented as what type of entity?

In the context of Data Flow Diagrams (DFDs), processes are represented as black boxes to emphasize the functional aspects of those processes without delving into the specific details of their internal workings. By treating processes as black boxes, analysts can focus on the inputs (data flows) that enter the process and the outputs that are produced, while not getting bogged down by how the internal operations are performed. This approach helps in maintaining a higher-level view of the system, which is essential during the initial phases of analysis.

In contrast, representing processes as white boxes would imply an examination of the internal workings, which can lead to excessive detail at a stage where a broad overview is preferable. Data stores and external entities have distinct roles in a DFD and do not pertain to the representation of processes in terms of detail management. Therefore, black box representation is the most appropriate choice as it aligns with the objective of keeping the DFD streamlined and focused on data flow rather than intricate process details.
