SQL HAS BECOME THE DATABASE LANGUAGE OF CHOICE BECAUSE IT IS FLEXIBLE,POWERFUL,AND EASY TO LEARN.

SQL IS A NON-PROCEDURAL LANGUAGE.PROCESS SETS OF RECORDS RATHER THAN JUST ONE AT A TIME AND PROVIDES AUTOMATIC NAVIGATION TO THE DATA


SQL PROVIDES COMMANDS FOR A VARIETY OF TASKS INCLUDING QUERING DATA,CREATE,UPDATING AND REPLACING OBJECTS AND INSERTING,UPDATING AND DELETTING ROWS.

ALL MAJOR RELATIONAL DATABASE MANAGEMENT SYSTEM SUPPORT SQL THUS ONE CAN TRANSFER ALL THE SKILLS GAINED WITH SQL FROM RDBMS TO ANOTHER .PROGRAMS WRITTEN IN SQL ARE PORTABLE,THEY CAN OFTEN BE MOVED FROM ONE DATABASE SYSTEM TO ANOTHER WITH LITTLE MODIFICATION.
