OK. I'm getting my head around this ERD model we've been given, but the VCAA ERD does not show cardinality.<br><br>So, from VCAA's viewpoint, what tool does show cardinality? A data structure diagram? In that case, what conventions are we to use to show cardinality?<br>
<ul><li>Chen?</li><li>Barker?<br></li><li>IDEF1X?</li><li>Cachman?</li><li>Martin / IE / Crow’s foot?</li><li>Min-Max/ISO?</li><li>UML?</li></ul>The <a href="http://www.vceit.com/postmortems/2010ita/a16.jpg">only data structure chart in last year's ITA exam</a> showed no cardinality at all.<br>
<br>So - will cardinality be represented in the ITA 2011 exam, or will students have to infer cardinality? <br><br>If cardinality <b>will</b> be represented to students, what notation will be used? <br><br>-- <br>Mark Kelly<br>
