I was greatly benefitted by attending the course.Mr.Prasad knowledge on the subjects, communication, delivery of the contents,clarification of doubts, off the class support in setting up VM Box,Gust OS,CS,ASM,RAC systems , and engaging the students during the class were outstanding.

Mr.Prasad has both practical and sound theatrical knowledge and is very rare in the training industry.At the end of the course my knowledge on Oracle RAC/ASM and confidence level to support RAC/ASM databases were very high. I would recommend anybody to take the course from DBA Technologies on RAC/ASM. Regards, Narayanan, Palakode Venkataraman
AbdulMoid Mohammed - India
I was struggling to find a better institute for Oracle DBA.After a strong search I found few among which one is quit famous(intentionally dont want to reveal its name) at ameerpet.After attending a demo I come to a conclusion that to catch the points in that massive class I should be a robot .Because there I found paying attention and getting interacted with the lecturer is such a tedous job. One day,one of my friends suggested me to join a demo at "DBA TECHNOLOGIES".Mr PRASAD is such a mentor who easily make his student involve into the subject becoz his way of delivering topics are really impressing.Real time topics are covered and LAB facility is full day. I always wanted to be a part of a game not to just watch a game and I achieved same in "DBA technologies". Thanks, Mohammed

Janardhan Sunkara-USA
This is Janardhan, I took Oracle DBA and RAC online training at DBA Technologies. This training was really good. Firstly, I am thankful to Mr. Prasad Mynampati and Anurag. I am felt more comfortable with RDBMS Core,RAC concepts and practicals after interacted with Prasad and Anurag. The way he teaching DBA concepts is really amazing because he took real time scenarios and share his experience with folks so that it gives me more insight into the technology and it is easy for me to remember the concepts. DBA technologies is always ready to assist us. The instructors at DBA technologies are very polite and patience. They are always ready to clear our doubts and solve our issues with the practicals with good real time examples. Another good thing in this training is that they ever rush in order to complete course. In sessions, Mr. prasad taught slowly and he ensure that every folk in the class is understanding the concepts and It helps me a lot because that I am a average student. Moreover, Mr. Prasad is a good affectionate communicator. So that I always feel free to ask all my doubts that in my mind whether it is big or small doubt and he also always feel more happy to address all my doubts. Once again I am thankful to Mr. Prasad and Mr. Anurag. I appreciate DBA technologies for their continuous services to IT field.
Ahmed Abdulla - India
I am a student at DBA Technologies... I think there are a lot of institutes in India that are Specials for Oracle databases, but the difference comes in how to deliver the information and choose the right place to receive these concepts.. So through my studies for a period of more than three months at the Institute I would like to tell you that the Institute is the best and by the way each class was very good and there were a lot of example and scenarios to make us understand very well.. . So for those people who are interested about oracle Cora DBA, RAC and APPSDBA,I recommend to them DBA Technologies.
Vijay - Singapore
Prasad is very knowledge and during training sessions he has not only given attention to detail but also explained live scenarios. I have joined with no DBA knowledge and after 4 sessions I cleared interview as a DBA with one year of experience. Thanks Prasad.
Raza - Switzerland
If you want theory and hand on practice, then you are at the right place. Mr Prasad is an exceptional trainer by any standard.
I have got more than 10 years of IT experience in Applications Administration. When it comes to Database Administration, I would say DBA Technologies is the ULTIMATE destination with no second thought. No corporate trainings can come close to DBA Technologies with respect to the QUALITY being delivered here. The commitment and passion that is shown in building up a student is amazing and incomparable. Students walked out of DBA Technologies after successful completion of their training should be very confident to involve in any kind of technical discussions in their entire career path. It is definitely my personal feeling and I would strongly recommend that any fresh graduate as well as those who are in the industry for a while, DBA Technologies is the RIGHT destination to have a strong foundation and to make the journey of their career smooth and confident.

Gary Adams - USA
I was a student in the Oracle DBA 11g online course. Our instructor Prasad is extremely knowledgeable in all things Oracle and he explained the material clearly and concisely. He took the time to make sure each student understood the material completely and made complicated topics very easy to understand. Prasad made certain that you not only understood all the material but that you would be able to apply everything that you learned to your real work environment. I would highly recommend Prasad and DBA Technologies for anyone who wants to become an Oracle DBA professional.
