There is high demand for professionals in the information technology (IT) industry, and Oracle
certifications are the hottest credential in the database world. You have made the right decision
to pursue your Oracle certification, because achieving your Oracle certification will give you a
distinct advantage in this highly competitive market.
Most readers should already be familiar with Oracle and do not need an introduction to the
Oracle database world. For those who aren’t familiar with the company, Oracle, founded in 1977,
sold the first commercial relational database and is now the world’s leading database company
and second-largest independent software company, with revenues of more than $10 billion, serving
more than 145 countries.
Oracle databases are the de
facto standard for large Internet sites, and Oracle advertisers are
boastful but honest when they proclaim, “The Internet Runs on Oracle.” Almost all big Internet
sites run Oracle databases. Oracle’s penetration of the database market runs deep and is not
limited to dot-com implementations. Enterprise resource planning (ERP) application suites,
data warehouses, and custom applications at many companies rely on Oracle. The demand for
DBA resources remains higher than others during weak economic times.
