This week, I made Flowcharts and Data Flow Diagrams for the website. A data flow diagram (DFD) is a graphical representation of the “flow” of data through an information system, modelling its process aspects. A DFD is often used as a preliminary step to create an overview of the system, which can later be elaborated.
For making DFDs I installed Dia Software. Dia is free(open source) drawing software.
