Can you name the key components of the Room library for database operations?

Key components of the Room library:

• Entity — a class that describes a table in the database. Each field corresponds to a column.
• DAO (Data Access Object) — an interface with methods for accessing data (insertion, update, deletion, queries).
• Database — an abstract class inheriting from RoomDatabase, which links Entity and DAO, and provides a database instance.

Example:

@Entity
data class User(
    @PrimaryKey val id: Int,
    val name: String
)

@Dao
interface UserDao {
    @Query("SELECT * FROM User")
    fun getAll(): List<User>

    @Insert
    fun insert(user: User)
}

@Database(entities = [User::class], version = 1)
abstract class AppDatabase : RoomDatabase() {
    abstract fun userDao(): UserDao
}
