Course Reviews

Excellent execution of the course. Everything was clearly explained and the instructor was responsive to questions and fully able to provide answers to those questions.

Andrew - DBA - March 2021


Thought it was a really good, informative course, I had a fairly basic knowledge of databases and it filled in many gaps plus gave me a lot if information to get more comfortable working with and using the information and tips provided.

Matthew - January 2021


The trainer was a great instructor with a clear and coherent teaching style. He broke down concepts well will diagrams which was really helpful. At some points the course was a little fast paced and it would have been good to go through some more details of the practical workshops.

Peter - Support Analysis - December 2020


Really enjoyed the course and the documentation manual will be very handy for the future. The trainer explained the content very well and was in engaging in is presentation. Will definitely use StayAhead again

Stephen - Development Manager - Manufacturing - December 2020


The trainer patiently provided a good quality training even though it was 100% remote. The pace was correct and the contents adequate to the topic at hand. The training was one on one which doesn't make it easy on the instructor, but he performed really well and was able to transmit the knowledge from the course manual with ease. Thanks to the trainer and to the whole team for providing this good experience. Much appreciated, Nicolas.

Nicolas - Finance


Lots of information to go through in just the week. Overall, learned a lot and the structure and operation of the databases makes a lot more sense than it did before.

Noel - IT
