In addition to DFD notations, DFD Level 0-N also has rules to govern the diagram. Any data flow as output from one process becomes input to another process. Data flows must begin and end with processes Data flows cannot be split and data loops are not allowed A process can modify the data or change status or content The data flow naming convention should reflect the data flowing between process and data stores A process must be dependent of its data inputs and outputs A process is always ready to perform a function or a task A data store must have at least one data flow going into it and one data flow going out it The following sites and PPT demonstrate the DFD Rules. 4.) Santati, M. (n.d.). Data Flow Diagram: Part 2. [PPT slides]. After getting familiar with DFD rules, please build the following diagrams. Review the Data Flow Diagram PPT for guidance. Using a modeling tool, build a Context Diagram and a Level 0 DFD for an imaginary car rental system. There are several examples of Context Diagrams and DFDs on the Internet that you can used to be creative on your assignment above. You will be particularly assessed on: Your ability to see what the module is all about and to structure your diagram accordingly. Your ability to use modeling software and apply diagramming techniques and terminology of systems analysis and design correctly and in context. Your paper submission must be in MS Word format.
