SQL stands  for  Structured Query Language.  It was developed
as  a  standard  method  to  query  (extract  data  from)   a
relational  database  and  do  other  operations  to maintain
relational databases.  Relational databases look at files  as
if they were simply tables.  SQL was developed years ago at a
theoretical  level but because of its inherent inefficiencies
and programming complexity, it has  been  very  difficult  to
create  workable  programs.   It  provides  the most flexible
approach to extracting data from a database.  It allows us to
extract data in  seconds  that  would  take  a  knowledgeable
programmer  hours,  days  or  weeks  to  extract, even if the
programmer  had   the   most   advanced   non-SQL   languages
available.   For  a sampling of the types of queries that SQL
can handle, refer to Appendix A.

Most database management systems on PCs,  minicomputers,  and
mainframes  have  an  SQL  interface.   So  far,  there is no
"better" language waiting to replace SQL so  once  you  learn
SQL, it should serve you for many years.
