[Year 12 SofDev] ER diagrams v data structure diagrams for 2011

[Margaret Iaquinto]

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.

ER diagrams are found in ITA in 2011.

So, can someone supply a way to differentiate the two? Or even websites for examples?

thanks

Maggie
