Oracle/DB

The eligibility criteria for Oracle Database Certification is multi-layered. For every course in Oracle database certification, the instructor-led training either in-class or online is an essential requirement. The initial phase where you are required to enrol in instructor-led training (online or in-class) does not need you to have any special qualifications. Once you have completed this phase then you need to clear either one of these exams:
1Z0-047 Oracle Database SQL Expert
1Z0-051 Oracle Database 11g SQL Fundamentals I
1Z0-061 Oracle Database 12c SQL Fundamentals
Once you have cleared any one of these exams then that's the only requirement for going to tier II which is a more advanced level. At this point you will have to decide whether you want to go for Oracle Database Developer Certification or Oracle Database Administrator Certification as each of these has their own sets of individual certifications & exam-levels.
