问题 I have a feeling I may have the understanding of this feature wrong coming from the SQL background. The documentation is sparse and I haven't been able to find a good example or an explanation.

问题 Firebase is known for its real-time data update, so this is a weird one for me. I am using Firebase 3 (New firebase console app. Want to add authentication later) and AngularFire 2. I started the app using Ionic's tab template so the app.js' router config should be the same.
