The Room persistence library it is an abstraction layer over SQLite.
The room is an ORM (object relational mapper) for SQLite database in Android. It is part of the Architecture Components released by Google.
Room is now considered as a better approach for data persistence than SQLiteDatabase. It makes it easier to work with SQLiteDatabase objects in your app, decreasing the amount of boilerplate code and verifying SQL queries at compile time.
Difference between SQLite and Room persistence library:-
In the case of SQLite, There is no compile-time verification of raw SQLite queries. But in Room, there is SQL validation at compile time.
You need to use lots of boilerplate code to convert between SQL queries and Java data objects. But, Room maps our database objects to Java Object without boilerplate code.
As your schema changes, you need to update the affected SQL queries manually. Room solves this problem.
Room is built to work with LiveData and RxJava for data observation, while SQLite does not.
