The fact that PL/SQL is portable is a good thing because:
Exceptions can be ported to different operating systems
Blocks can be sent to the operating system.
PL/SQL code can be written on one operating system and executed on a
different one.
PL/SQL code can be run on any operating system without a database.
PL/SQL is easier to learn and more efficient than C or Java
PL/SQL allows basic program logic and control flow to be combined with
SQL statements
PL/SQL extends SQL by including conditional statements , reusable
program units , constants
tools can be used to develop and test PL/SQL code
