Please, please fix subtitles. Starting from about section 4 they contain weird mistakes like parameters -> barometers, SQL -> sequel, etc.
Good Coverage of important topic,explanation is precise & simple.It would be good if AWR reports explanation would be included in the course.
I am very disappointing to take this course because i'm not getting my question reply here and second thing is that some topic are missing here like partitioning, Hints and global indexing etc. which is vital as perspective of performance tuning.
Partial. O sa vad mai departe. Subtitrarea merge greu, parti intregi sunt sarite. Accentul este puternic, si faptul ca lipsesc subtitrari, fac greu de urmarit parti importante
Seria bom ter legendas em tudo. Alguns trechos nçao temos a legenda em ingles. Como não tenho ingles fluente, a legenda ajuda a entender melhor o que é falado em ingles.
Excellent course. Well paced. Dense with good information, but not overwhelming. Having gone through the course, my knowledge of optimization has been bumped up to the next level.
The Course was a good refresher of the concepts. I would recommend to add more topics on tuning such as SQL Profiles.
Detailed content and great presentation. I have learned a lot on these optimization techniques. I would recommend this course for others too ...
well structured course and the thing which I loved the most is everything is explained with easily understandable examples.
Excellent course on SQL tuning,short and to the point with ample examples to clear the concepts. Just one request to him, kindly add few lectures on "SQLT" tool as it's one of the main tuning tools for poorly performing SQL's.
English is not always super clear and easy to follow, but contents are great and the course is very well paced
O Curso aborda de forma geral os conceitos que envolvem performance Tuning. É recomendado que o aluno já saiba alguns conceitos básicos sobre o assunto.
It is a great course and instructor way of teaching is really engaging and interesting. I highly recommed it to those who want to master in SQL tuning.
Till now, the concepts are very well explained. The architecture of Oracle is very well explained. I see instructor possessing very good knowledge on the subject. Hoping to complete the full course and provide the final feedback.
