Which type of Data Flow Diagram (DFD) focuses on the business and business activities?

The correct choice is Logical DFD because it emphasizes the flow of data through a system and the processes that transform that data, reflecting the business activities and functions rather than the technical implementation.

In a Logical DFD, the focus is on what the system does, illustrating the processes involved, the data inputs and outputs, and how these elements interact with each other in the context of business functions. This type of diagram is essential for analyzing the processes within a business and understanding the overall flow of information without considering the physical details of how those processes are implemented.

Physical DFDs, on the other hand, depict the actual implementation of the processes, including how data is stored and the specific hardware or software being used. They are more concerned with the technical aspects and less with the high-level business functions.

Context DFDs provide a broad overview of the system, showing the system as a whole in relation to external entities but do not delve into the specifics of the business activities as extensively as a Logical DFD does.

Primitive DFDs represent the lowest level of detail in a DFD, focusing on the most basic operations but lack the broader context that the Logical DFD provides regarding business activities.

Therefore, the Logical DFD is the appropriate
