Which type of DML should I use?
Use the short DML statements—to get any error that occurs during bulk DML processing that immediately interrupts the control flow (by using a try...catch construction). This behavior is similar to how exceptions are handled in most database languages.
Use the Database class methods—if you want to allow partial successes of a bulk DML operation. The DML statement can inspect the rejected records. When using this flow, you can write code that never throws a DML exception error. Instead, your code can use the database results list to judge success or failure.
Database methods also support a syntax to throw exceptions, similar to DML statements.
