Room Database Demo

This is a demo app on how to implement Room persistance library, making use of LiveData in Android app

Key Points of Room Database:

• Room is a part of android architecture components.
• Room is a database layer on top of Sqlite Database
• Room Database helps us to verify the sql queries at compile time instead of run time as a results there would be no risk of runtime error that might crash the app.
• Room DB helps us to reduce the boilerplate code and improves the code readability.
• To represent Room Database we need to create abstract class which extends Room Database.
• To represent each table we should use Entity class
• To communicate with database we need to create Data Access Objects (DAOs)
