The PL/SQL language is tightly integrated with SQL. You do not have to translate between SQL and PL/SQL datatypes: a NUMBER or VARCHAR2 column in the database is stored in a NUMBER or VARCHAR2 variable in PL/SQL.
This integration saves you both learning time and processing time. Special PL/SQL language features let you work with table columns and rows without specifying the datatypes, saving on maintenance work when the table definitions change.
