ReplyDeleteDear Suresh Khanal,
ReplyDeleteIf you go through a Kendall and Kendall's Book it shows Context Level and Zero "0" Level as a different level DFD. According to Book by James A. Senn Both are same.
So, Whatever method you follow just mention the reference you have taken from that book.
From my point of view James A. Senn's book have clear and Correct approach toward DFD.
