This course helped me understand how small changes can have a big impact on query performance. The coverage of SQL internals was especially enlightening.

The course content is gold for Oracle users. I’ve already applied the indexing tips to improve our legacy system's performance by a noticeable margin.

I had no idea how much improvement proper indexing could bring until I took this course. The difference in performance was immediate and significant.

I was impressed by how comprehensive yet digestible this course is. Every concept is backed by a real-world example, making it incredibly useful.

Tuning Oracle SQL always felt like a guessing game, but this course gave me a solid framework to analyze and improve performance with confidence.

I appreciated how this course didn't just explain what to do, but why each tuning step matters. That context made all the difference for me.

Excellent pacing and delivery. The module on Common Table Expressions clarified a lot for me, and now I use them much more strategically.

A solid course with deep technical insight. The focus on understanding execution flow and resource consumption added a lot of value.

Even with years of SQL experience, I learned plenty of new techniques. The course helped refine my approach to query optimization.

Very insightful and well-organized. It walked me through performance issues I face daily and showed me exactly how to fix them.

Loved the use of practical demonstrations. Seeing performance improvements side-by-side really helped solidify the concepts.

The content was comprehensive, well structured and delivered with clarity. Highly recommended!

Excellent coverage of the concepts from the basics with examples. Easy to understand.

Nice Course. Trainer is quite experienced. Good course for a beginner. Recommended.

In terms of mere content and my personal interest in the topic, five stars. One star subtraction for the sometimes clunky English at the test sections that made it a bit hard to understand what the exact question really refers to. Neither the instructor, nor me are English native speakers, so I am forgiving to some extentm but written questions in a test should be stated in proper language. On some occasions, I would have appreciated a deep dive into the technicalities a little further: more complex explain plans, specific hints etc.

Some good points in various topics. Good starting point for learners. Yet the course might improve by including more use cases and increase breadth and depth of db tuning.

i would have expected more details about use of data pools
