[Year 12 IPM] DFDs and SDLC Question

[Roland Gesthuizen]

Here are some suggestions from the VITTA resource bank. 

(1) Slideshow that discusses how data flow diagrams (DFD) can be can be used
to model existing and proposed information systems. Some good examples and
illustrations.

(2) PP Presentation on developing data flow diagrams.

(3) DFD Activity 1 (first in a collection of 10 available)
http://www.vitta.org.au/resources/detail.php?doc_id=90 

(4) Notes on Data Flow Diagrams, draws on "Systems Analysis & Design and the
Transition to Objects" by Dewitz.
http://www.vitta.org.au/resources/detail.php?doc_id=2308 

(5) I recall that Kelly Beattie of Berwick SC gave a talk about this topic
at the 2004 VITTA conference.

The 2005 VITTA conference is only around the corner ...... 
have you registered yet ;-)

Subject: [Year 12 IPM] DFDs and SDLC Question

Hi Everyone,

As a first year teacher I find this mailing list a great resource!  So
thankyou to all of the contributors.

I was wondering if anyone has any easy to understand or useful worksheets
etc. on Data Flow Diagrams (context diagrams and the level 1 & 2 DFDs).  I
did these diagrams in my first year at uni and now, I can't seem to remember
much at all.

The other question I have is in the SDLC does testing come into the design
phase and documentation in the implementation phase?  I've read a few books,
some with testing and documenting coming into the implementation phase. 

Any advice would be great.

Thanks in advance,
