I believe a training should be something that will fill in an identified gap. It should be more practical rather than theoretical or an academic exercise. It’s good if the school brings practitioners on board as consultants who will give hands on knowledge require to meet the identified gaps
My general comment is that I am really disappointed with the course itself. I was expecting to gain some knowledge about Business Intelligence systems, understand different BI techniques and BigData. The problem here is not about the consultant or the quality of the material, the problem is that I signed up for a different course to what was actually delivered.
