If a high level design is decomposed into Sub-subfunction then level of DFD will be___?*Level 0Level 1Level 2Level 3

The level of a Data Flow Diagram (DFD) after a high-level design is decomposed into sub-subfunctions would be Level 2.

Here's why:

• Level 0: This is the highest level of a DFD. It provides a broad overview of the entire system.

• Level 1: This level provides a more detailed breakdown of the system. The main functions are identified and represented as processes.

• Level 2: This level provides an even more detailed breakdown of the system. The main functions identified in Level 1 are decomposed further into subfunctions or sub-subfunctions.

• Level 3: This is the most detailed level of a DFD. It provides a detailed description of the operations within each process identified in Level 2.

So, if a high-level design is decomposed into sub-subfunctions, it would be at Level 2 of a DFD.
