When should you use Room database in Android development?

Room is an abstraction layer over SQLite that helps in handling database operations in Android applications. You should use Room when:

You need local data persistence for your application.
You want to perform complex data queries easily using SQL.
You need to manage relationships between different entities in your database.
You want compile-time checking of SQL queries to avoid runtime errors.
Your application requires scalability and the ability to handle a large amount of data efficiently.
You prefer a reactive programming model such as LiveData or RxJava for observing data changes.

Here's a simple example of using Room to create a database entity and DAO:


        @Entity(tableName = "user_table")
        public class User {
            @PrimaryKey(autoGenerate = true)
            private int id;

            private String name;

            public User(String name) {
                this.name = name;
            }

            // Getters and setters...
        }

        @Dao
        public interface UserDao {
            @Insert
            void insert(User user);

            @Query("SELECT * FROM user_table")
            List getAllUsers();
        }
