I've made a number of pizza's and coca's lately and I thought about making a focaccia... When reading about coca, focaccia was mentioned, and when reading about focaccia, pizza was mentioned.
The pizza I make has yeast and some olive oil. The coca has baking powder and lots of oil, and the focaccia also has lots of oil, but no yeast nor baking powder.
But I've seen recipes with coca's with yeast and less oil (=pizza recipe)...
So, is there a clear definition or is it just the name you care to use?
