PL/SQL is Oracle�s procedural language extension to the SQL language, It has its origins in ADA, a high-level programming language developed for the US Department of Defense. ADA was named after a daughter of Lord Byron, Augusta ADA, Countess of Lovelace, a 19th century mathematician, whom many regard as the world�s first computer programmer because of her work with Charles Babbage�s Analytical Engine. PL/SQL introduces 3GL-style procedural logic into the world of declarative logic. Its first incarnation was in 1991 as the �procedural option� for Oracle RDBMS Version 6.0. At about the same time, PL/SQL debuted on the client side in SQL*Forms Version 3.
