Ionic storage package,SQLite vs FireBase


Hello everyone…
So I’ve been studying ionic and working on an Ionic project at the same and recently I got stuck on a phase that I should choose a technique for storing data! Ive been searching for it for a long time and read about ionic storage ( and its relation with SQLite) and FireBase but i couldn’t sum it up to get to a conclusion.
In fact Im using ionic-cordova camera plugin and now i want store that image but I cant choose between them as database…
can you help me know a little bit more about their concept and features?
Many thanks
