What methods exist for performance tuning?

The best way would be to perform join at the database, the classical way is when we have two tables that we can bring together by making placing a join component between them. Alternately we can write a query to make the join at the level of a database. The advantage is that only one hit is sent to the database instead of two (the classical method). This makes a real difference in improving performance.
