Although customer is the real person who buy souvenir, it is the CS Assistant who accesses the system for storing the order details. About us page... Advanced Projects, Arduino Projects, IOT Projects on. Why are you drawing a DFD? The way how order details are stored physically is to be decided later on when implementing the system. Therefore, we make the data flow from CS Assistant to the Buy Souvenir process. It also shows the participants who will interact with the system, called the external entities. A callout shape is used to list out the kind of details that can be inquired by passenger. Level – 0 Data Flow Diagrams – These diagrams describe general high-level processes (the first level of numbering is used), external entities, data flows, and data stores. First Level Data flow Diagram(1st Level DFD) of Hotel Room Booking System : First Level DFD (1st Level) of Hotel Room Booking System shows how the system is divided into sub-systems (processes), each of which deals with one or more of the data flows to or from an external agent, and which together provide all of the functionality of the Hotel Room Booking System system as a whole.

Higher-level DFDs are partitioned into low levels-hacking more information and functional elements. In Yourdon & De Marco system processes are represented by circles, while in Gane & Sarson processes are represented by squares with rounded corners.
