Oracle DBA is a good choice

Limited implementation guarantee

For many years we have been one of the few seminar providers to offer a performance guarantee with guaranteed dates for all seminars. For you, this means a high degree of predictability and reliability.

Due to the current COVID19 crisis and the massive effects on the seminar business, it is currently not possible for us to guarantee all training courses. In individual cases, seminars can therefore be canceled in exceptional cases. We ask for your understanding.
