I heard that the context analysis diagram has different levels. I couldn't find this in .Net, but I have seen that a DFD has different levels.
Do context diagrams have any levels (
level2)? If yes, please suggest some examples.
The answer depends upon what type of Context Diagram you are referring to.
This diagram is the highest level view of a system.
The IDEF0 process starts with the identification of the prime function to be decomposed. This function is identified on a “Top Level Context Diagram,” that defines the scope of the particular IDEF0 analysis. ... From this diagram lower-level diagrams are generated.
