<p class=MsoNormal style='margin-bottom:12.0pt'>Hi all. I'm playing with an SRS
based on the Cantina (study design p.84).<br>
<br clear=all>
I've got to the context diagram, and I've attached a first draft. I'm not
100% of a couple of things:<br>
<br>
1. I have excluded the customers as an external entity since they don't
interact with the system: the waiter does.<br>
<br>
2. I included the transmission software as an external entity since it takes the
text file from the ordering software. But if the text file is saved
should it then be considered outside of the system rather than an active data
store within the system? In that case, the transmission software should
not be included at all.<br>
<br>
Any ideas?<br>
<br>
Cheers<br>
Mark<br>
