As a Java developer, I often find myself interacting with databases and writing SQL queries. After attending Vlad's High-Performance SQL, I found answers to many problems that I faced over the years.

Vlad has a dynamic approach to teaching that motivates and engages everybody in the room.

The presentation covered a lot of fascinating topics, and the content was well structured.

Every section had real-life code examples helping solidify the information presented.

This was a great training course that covered a lot of advanced SQL concepts.

Our company has been delivering an ERP solution for laundries for more than 25 years. Our application uses Oracle, Java, Spring, and JDBC as its backbone.

Most of the performance problems reported by our customers find their root cause in the persistence layer.

During his course, Vlad showed us how we should tackle these kinds of issues, breaking up the execution time of a statement into atomic bits and improving the performance for each of them. We found that optimizing the persistence layer is much more than just writing an SQL query as efficiently as possible.
