I started trying to clean up the article -- I think it was a rough translation from German.

Nope, this is just me trying to convey the information that i know is correct, but am not allowed to just copy and paste... Beta_M ^talk, |^contrib (Ë-Mail)

I think it's quite good, it just needs some examples that my school might be able to provide.(Contact Rossmoyne Senior High School in Perth Australia)

[edit] Example might be needed

Maybe someone should give an example where some c code (or code in another language)can be transformed into a DFD

[edit] Removed

Removed *Chapter from a book by Edward Yourdon Because it is a broken link.

[edit] Attempt to improve the page

I've attempted to start improving this page and work towards removing the clean-up tag. Any suggestions or additions would be much appreciated. Ranglin 06:19, 4 November 2005 (UTC)

[edit] Merging

I think it is pretty obvious it should be merged with Data_Flow_Diagram. Lewispb 10:33, 4 April 2006 (UTC)

I'll tag it. Melchoir 23:29, 13 April 2006 (UTC)

Agreed. There's a lot I could write on this too... — Phil Welch (t) (c) 23:45, 1 May 2006 (UTC)

Who's going to do the merging? If I can find some free time I'll have a go. TerrorBite 04:50, 4 May 2006 (UTC)

Done. Albanaco 18:48, 9 May 2006 (UTC)

[edit] An article about a diagram without a diagram!

Can someone who knows the correct symbols etc. make a complete data flow diagram, including as many of the standard symbols as possible, and add it to the top, or near top of the article - it seems stupid to try to describe a diagram without an actual example to look at!--Wierdy1024 22:19, 4 June 2006 (UTC)

I was planning to do that, but I'm a bit swamped with life right now. If no one beats me to it, I'll write up a DFD about Wikipedia, and post it to Wikipedia. — Philwelch t 02:05, 5 June 2006 (UTC)

That would be awesome Philwelch, if you could squeeze out the time...Regards to all--The world salutes the Rising Star...Try to be One 14:01, 8 December 2006 (UTC)

A DFD of Wikipedia? Hoo-boy, "That way lies insanity!"  ;-) But as a non-expert, knowledge-seeking passerby, I too notice the irony of an article about a diagram without a diagram. Ditto for the Activity diagram stub that user 202.92.102.220 mentions below. Fortunately, the references have some diagrams.

[edit] Criticism of DFDs

Perhaps we should include a section on the problems/limitations of using DFDs for system analysis and design. A reference to use cases, activity diagrams as a better solution?

Good idea, if  it could be kept brief, encyclopedic, and NPOV. Like the pros/cons sections in the use cases article. Bad idea if it just turns such a section (and this Talk page) into a Hyde Park of rhetoric and debate. I've actually seen people get hot under the collar on subjects like DFDs.

Can you come back to write the problems/limitations section? I see from your contributions page and your Talk page that your IP Address has so many users, it's been blocked unless they each sign in as a member.

[edit] Data flow diagram

Real time examples for the data flow diagram for "Top-down approach" and "Event partitioning

approach" will leads to understand the concept well.
