Process Model by Data Flow Diagram.

Hello geniuses!

I'm afraid i'm struggling with a question relating to Data Flow Diagrams, I have been given a case study and am now being asked to create a Data Flow Diagram for this new website creation.

However, I've tried, I really have tried, to understand these Data Flow Diagrams but am struggling still, I was wondering if anyone knew anything about them?

I won't put the whole question up here but if anyone would be so kind as to contact me I would be very very thankful!

Just any help will do, even if you don't think you know that much it's probably still more than me!

Thanks everyone,

Gareth

 

If you are looking for software, Dia is a good free one.

 

Thanks for all your replies!

Basically I need to create a DFD for a simple e-commerce website, the two textbooks I have on Data Flow Diagrams are so damn complicated and i'm finding it very hard to understand.

Once I figure out how to do one I will probably use one of these softwares that you mention!

Thanks everyone,

Gareth
