Oracle Database 11g: Program with PL/SQL 1Z0-144

PL/SQL is Oracle Corporation's procedural extension for SQL and the Oracle relational database. PL/SQL is available in Oracle Database, Times Ten in-memory database, and IBM DB 2. Oracle Corporation usually extends PL/SQL functionality with each successive release of the Oracle Database.
