If I have a table, lets say trip_information.
Then for each trip there is are trip "highlights".
Each "highlight" contains a title and a description.
You don't know how many highlights there will be per trip, and you don't want to create one field in the table where someone would just paste HTML.
How would one go about bulding a relational-setup where you can have such a thing? A great example is this:
You see there's 'Trip Highlights' with a few pictures, a title, and a description. Surely all of these are not just HTML pasted into a field - right? :S
