It presents a brief history of DFDs and its function. It has examples using the Gane and Sarson Notation. The author even gave some advices for proper DFD construction.

Gives good definition and function of DFDs. Describes the different components and their relation to each other. it uses examples of modelling techniques.

An illustrative approach in constructing a DFD. It describes the system process in terms of output in input. Dataflow notations are also discussed.

A document on the components of a data flow diagram. It shows the different processess and the importance of each.

A more in-depth analysis of the ER diagrams. Reader must posses mathematical understanding of cardinalities to understand.

Compares the DFD with the Entity-Relationship Diagram (ERD) and how each is tied up with the other. It gives an abstract view of the process involved in data modelling and how the pioneers like Gane and Sarson DeMarco established or formalize analysts' anecdotal and idiosyncratic data safaris.

An overview of all the components of a DFD. Gives a short introduction and purpose. It includes some advance notations that will help in more complicated processess.

Describes Data Flow Diagrams in the simplest way and in basic terms.

Shows a very complicated example of a DFD. It however gives adequate explanation of the different functions and subfunctions and relates it to real-world entities such as databases and/or knowledge bases.
