Hi, I am currently thinking of whats better to learn UML or data flow diagram (DFD) for systems analysis and design? I am currently reading a book about UML and planning on learning it. I have learned DFD back in college but forgot most of the basics of it. I am not sure if UML and DFD should both be learned if you want to just familiarize yourself again on some stuff about systems analysis and design? and is UML part of systems analysis and design or just a prerequisite for object oriented programming? Thanks in advance for any replies!
