コース - PostgreSQL Essentials
It was clearly tailored to be very appropriate to our purpose which made it extra helpful. I really liked the zoom format as it helped me focus with the material right in front of you all the time and the trainer able to add illustrations and markings on to it as he explained. The trainer answered all our questions in a very satisfying way and I felt surprised at how much I was able to learn in one day. Usually i get tired of training by the afternoon but this was very engaging right through to the end. Pace was perfect and detail went into the right areas.
