It only contains one process node Process 0 that generalizes the function of the entire system in relationship to external entities. Different templates are available depending on the type of review new or updated and sources used to identify studies. Level 1 DFDs are more of a general overview but they give more detail than a context diagram.

Also level 1 DFD contains data. This is the main difference with level 1 DFD. As you saw above context DFD contains only one process and does not illustrate any data store.

Expand the context diagram into a level 1 DFD. Level 1 data flow diagram. Draw data flow diagrams can be made in several nested layers.

Data Flow Diagram Levels. Level 1 DFD breaks down the main process into subprocesses that can then be seen on a more deep level. The standard symbols are important components of data flow diagrams.

Break the single process lump into detailed processes. Definition and example with explanation. The flow diagram depicts the flow of information through the different phases of a systematic review.
