In general, this book uses the DFD symbol developed by Gane and Sarson to illustrate how DFD is produced. The creation of DFD is broken down into steps and covered in detail to make it easier for the reader to grasp and subsequently be able to construct an understandable DFD. This eBook is intended for lecturers and students as a teaching and learning material for the Logical Designs topic in System Analysis and Design.  \nAbout the author  \n Aminah Bibi bintiBawamohiddin   \nA lecturer in the Information Communication and Technology Department, Ungku Omar Polytechnic.
