• SQL Help and Tutorial - SQL Features, This section details information about Structured Query Language (SQL).

  SQL is the language used to access the data and structures within a relational database. PL/SQL (an Oracle specific SQL extension) allows basic program logic and control flow to be implemented around SQL statements. Most RDBMS vendors have a similar set of extensions or allow SQL statements to be embedded within a normal development package such as Visual Basic or C++. PL/SQL is covered elsewhere on this site.
