Flow diagrams in general are usually designed using simple symbols such as a rectangle, an oval or a circle depicting a processes, data stored or an external entity, and arrows are generally used to depict the data flow from one step to another.
A data flow diagram DFD is a graphical representation of the "flow" of data through an information system. A data flow diagram can also be used for the visualization of data processing structured design.
It is common practice for a designer to draw a context-level DFD first which shows the interaction between the system and outside entities.
This context-level DFD is then "exploded" to show more detail of the system being modeled. Data flow diagrams were invented by Larry Constantine The sponsor of a project and the end users will need to be briefed and consulted throughout all stages of a system's evolution.
With a dataflow diagram, users are able to visualize how the system will operate, what the system will accomplish, and how the system will be implemented. The old system's dataflow diagrams can be drawn up and compared with the new system's dataflow diagrams to draw comparisons to implement a more efficient system.
Developing a DFD helps in identifying the transaction data in the data model.
