Certification courses are available in MySQL database administration, Java programming, enterprise application development, Oracle database 11g, system administration, network administration, security administration and Oracle database 10g. Discount packages are also available.
Like a traditional university, Oracle offers introductory courses and more advanced courses. This is especially true of "job role" training, which aims to qualify you for specific professions.
If you already know the material, it may be unnecessary for you to take a course. Some Oracle University subjects allow you to take the exam without doing any coursework and earn your certification.
