CI for dummies

They keyword for me in understanding and working with CI/MVC is DRY (Don't repeat yourself). The minute you repeat a line of code you should think for a minute and consider if it wouldn't be better to abstract the code a little.

Since you're a beginner in CI I would suggest what minimal design says, two sets of data, use two models. However, normally I'd opt for one controller one function.
