Very effective course. I especially liked the parts explaining how different data types impact performance. It's something often overlooked but crucial in tuning.

Very useful for application developers like me who often struggle with database performance. It gave me the tools to optimize without relying solely on the DBA.

As a data analyst, I found this course especially useful in improving report generation times. The optimization techniques are easy to follow and impactful.

The structure and flow of the content are excellent. It builds your understanding step-by-step, and by the end, you truly feel in control of your queries.

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.

Fantastic delivery with clear examples. I now know how to spot inefficiencies just by analyzing the query plan—a skill I lacked before.

This course filled a major gap in my SQL knowledge. I always knew tuning was important, but now I have a structured way to tackle it."

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.

A well-rounded course that doesn't just skim the surface. The lessons on query rewrite strategies were particularly helpful.

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

The hands-on approach is what sets this course apart. Applying what I learned to real Oracle workloads was seamless.

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.
