(i) SQL enables end user and system persons to deal with a number of database managment systems where it is available.
(ii) Applications written in SQL can be easily ported across systems. Such porting could be required when the underlying DBMS needs to upgraded because of change in transaction volumes or when a system developed in one environment is to be used on another.
(iii) SQL as a language is independent of the way it is implented internally. A query returns the same result regardless of whether optimizing has been done with indexes or not. This is because SQL specifies what is required and not how it is to be done.
