More than 80 percent of individuals who earned a certification in the last five years reported that it was a worthwhile endeavor, according to Global Knowledge's 2011 IT Skills and Salary Report. Oracle PL/SQL certification offers a way to expand your skill set and demonstrate your expertise in working with databases.
Oracle describes Procedural Language/Structured Query Language, or PL/SQL, as a 3rd-generation language created to process SQL commands. Its syntax was built for this purpose, and it supports the same datatypes as SQL. This language is integrated with Oracle database products, which makes it a powerful tool for administrators, computer programmers and resident IT experts in any business. Oracle Database 11g incorporates enhancements to PL/SQL designed to improve usability.
