Can you list the main parts and components of the Room library for working with databases?

Main parts of the Room library for working with databases in Android:

• Entity — classes that describe database tables. Each field of the class corresponds to a column in the table.
• DAO (Data Access Object) — interfaces with methods for data access (insertion, update, deletion, queries). Room generates the implementation of these methods.
• Database — an abstract class that inherits from RoomDatabase and combines all DAOs. It is used to create and access the database.

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
}
