Using: ColdFusion 10, JQuery, IIS 7.5

I'm creating a system where people can submit their text articles to me and I can apply edits/corrections and send it back to them.

However I don't want to lose their original work. I want them to see where I made edits.

StackExchange pretty much does what I want by showing when a post was edited and then you can see the history of changes.

Can anyone please suggest how to go about doing this? Everytime an edit is made, it has to be written to the database. But how do I show what was edited? It could be 1 word in a whole paragraph... how would I highlight this?

I just need some pointers if possible at what to think about and what to use if anyone has the time to help me out.
