  1. I took SQL & PL/SQL developer training at DBA University. Without having any technical background & work experience I thought this course might be very difficult to pursue. But our instructor made the entire experience a cake walk. He was very patient in answering questions, clarifying doubts & let everyone take their own time to understand difficult concepts.
    The lab was available during weekdays & weekends for 10 hours a day. The course material provided is adequate & self explanatory. Apart from the exercises provided in the material, instructor provides additional material for practice.

    On the whole I would give 9/10 for this training experience.

  2. I completed short training course on Oracle PL/SQL from DBA university. I found DBA university to be very interesting. The lecture and training materials are well organized , the lab practice helped me very much. Overall It is the most effective way of learning Oracle PL/SQL.

  3. I’ve taken two classes at DBAUniversity – both with Srini. The PL/SQL class and the Oracle DBA training. DBA Training was very hard for me but Mr. Srini was extremely helpfully. Any time I had trouble with the work, he will schedule extra time outside class time to help me get it done. Not only that but he has also helped me to prepare my resume. I am planning and prepare to take Oracle certification.

    The classes are well thought-out and well documented. The training environment is fabulous. The class is online but it is alive class. This was my first time to take a class online. I will definitely do it again if it is conducted by Mr. Srini. The lab work are very helpful. They provide machines to work on remotely. Mr. Srini keep on calling each student to make sure you understand want he is talking about. He can even ask questions random on anyone in class.

  4. I took the PL/SQL Course. The lecture and training materials are well organized , the lab practice helped me very much. It is the most effective way of learning Oracle PL/SQL. The Instructor was very knowledgeable, patient and answered questions. I would recommend for anyone who is interested to learn this course.

  5. This is a perfect training for a person with some IT experience and little or no Oracle exposure. It provides very useful and informative demos of activities performed by Oracle DBA. It covers most of practical aspects for DBAs and provides recommendations for real-world situations. Students have an opportunity to spend hours doing hands-on exercises in Linux virtual environment. I would like to especially stress a unique teaching style with a lot of visual explanations and references to person’s daily life experience and to common sense. An excellent, efficient and inexpensive starter!

  6. Michelle’s Oracle 12c RAC class of DBAUniversity in Chicago was truly an awesome experience for me. I’m an Oracle OCA, and still found lots of new tools and techniques to try in this class. We were provided with a working VirtualBox VM (containing Oracle Linux) that eventually contained an entire functioning Oracle 12c RAC database. We covered many subjects including networking, containers, pluggable databases, high availability, ASM, rman, services, listeners, registries, failovers, healthcheck, EM, wallets and nodes. We went through the steps to create our own RAC and Data Guard systems.

    The class is done with Cisco’s WebEx classroom software which ran well on both my Mac and PC. WebEx is great because the teacher can work on their machine, a remote lab machine, or your machine – and the whole class can view at the same time. It has a whiteboard, chat area and live video. Michelle wrote the class ebook which is easy to follow, and has lots of great exercises. It contains probably 4000 pages worth of information condensed down into a few hundred pages.

    Michelle as a teacher is a wonderful experience. She is extremely knowledgeable and experienced in things Oracle, and manages to keep the atmosphere lighthearted and fun. The idea that you could have a group of people remotely spread around the country, all with separate networks on their machines at home – with cutting-edge RAC 12c databases running on them – and keep all of this going for a month is quite a feat. Communication-wise, Michelle spent a lot of time outside of class answering my emails and helping me with my technical issues quickly and completely.

    Each student’s machines were different, and there was an array of problems that cropped up. Each time I would think to myself – okay, this is it. Michelle is going to finally crack and have a nervous breakdown. But it never happened. She always had the next thing to try, and a graceful way around anything we threw at her.

    I haven’t quite finished the Data Guard exercises yet, but since I own the VM and it’s on my machine — I can do the exercises and practice anytime I like. This is my third class with DBA University and they’ve all been fantastic. This is especially true when you compare the cost to other schools around the US. For the price, there’s nothing comparable.

    The following is for Srini’s PL/SQL and regular Oracle DBA training:

    The classes are well thought-out and well documented. The training environment is fabulous – just like being there, but from whereever you want. (However, you really need to connect via wire – not wireless, for the sound to work well). They provide machines to work on remotely – I’m guessing they’re hosted via Amazon. The computer environment was perfectly prepared both times and I wasted no time on that.

    Srini is an excellent trainer – very patient with his students. He’s always very enthusiastic about his subjects and about getting his students to understand. It’s impossible to find Oracle classes anywhere for this price. They also let you go to the first day of class and if you really don’t like it, you can still back out. It’s a small company, so they’re very reasonable and work hard to protect their reputation.

  7. I can challenge that DBA University is the best when it comes to online DBA training. I completed my Oracle DBA 11g course last month and the experience was great. The virtual board, dedicated remote server, excellent Webex session provides a classroom like atmosphere. Two things that distinguish DBA University are its low price and excellent staff knowledge. I was astonished by the amount of patience and knowledge my trainer had and there is none in the class who was left behind. I gained good knowledge not only with the DB concepts but also had a chance to learn Linux and shell scripting. You can be Industry ready when the course is complete. Thank you DBA university for the wonderful experience and knowledge.

  8. The course was pretty hands-on and informative. Lots of lab work and real life senario’s. I will recommend it to anybody looking for a career in DBA.
