Higher-level DFDs are partitioned into low levels-hacking more information and functional elements. The sources and data flow diagrams express flows of data indicated with an arrow between processes and/or data stores and/or external entities.

The garment management receives the order and distributes the work to its employees. Every process has a name that identifies the function it performs. A level 0 data flow diagram (DFD), also known as a context diagram, shows a data system as a whole and emphasizes the way it interacts with external entities. DFD Level 2 then goes one step deeper into parts of Level 1 of Hotel Room. As you can see This same process can be applied to each process appearing within a level 1 DFD.
