<DIV>In the study design for 2011, a KK includes data structure diagrams and ER diagrams. Looking on the Web for some help, it appears they are similar and perform similar functions. Perhaps the ER diagram is a subset of the data structure diagram. Haven't fully grasped this yet.</DIV>
<DIV> </DIV>
<DIV>ER diagrams are found in ITA in 2011.</DIV>
<DIV> </DIV>
<DIV>So, can someone supply a way to differentiate the two? Or even websites for examples?</DIV>
