Data Flow Diagram at a Glance

The concept was popularized by Ed Yourdon and Larry Constantine in the late 1970s. It was known as “Data Flow Graph” at that time. The term was actually coined by David Martin and Gerald Estrin. They used the concept in software engineering, later the concept took the name Data Flow Diagram and used in various other fields including in business analysis and marketing strategy formulation.

There are some universal symbols and notations used in DFDs. You have to know the meaning and applications of these symbols and notations:

  • Yourdon and Coad
  • Yourdon and DeMarco
  • Gane and Sarson

These are the three basic systems of DFD named after the developers of the concepts. In the first two systems, mainly circles are used while the third one uses rectangles with rounded corners also known as lozenges. You need to be consistent in using the symbols, i.e., you cannot jump from one system to the other. Whatever convention you use, the symbols depict 4 basic components in DFD:

  • External Entity – They act as the sources of data which is either send to another source or received like a customer of a business, a computer system, another organization, etc. they are used mainly on the boundaries of a diagram.
  • Process – It is what changes a data. It provides an output. It may perform a calculation, sort data on the basis of logic, or direct a data to another direction. You have to use snort levels to describe the process.
  • Data Store – It is what files a data or preserves it for future use. Data store accepts unpretentious labels.
  • Data Flow – It is the route that the external entities in a diagram take. It is also used in directing the processes and data store in a diagram. It depicts the line of action between the extra components and is revealed with arrows, normally considered with short names.

Below are two popular types of DFD symbols:

So, the basic rules of using DFD are as follows:

  • You have to use any one system.
  • Each process contains at least one input and one output.
  • A data store should contain at least a data store in and data store out.
  • A process must go to another data store or another process.

As stated before, DFD can have different levels. It starts at Level 0 and can even go to Level 3,4,5 and even higher. Uses of levels depending on the industries and purposes. Some fields where Data Flow Diagram is regularly used are Software Engineering, Business Analysis, Business Technical Requirements, Business Process Re-engineering, and so on.
