Get the most out of your data access layer

Want to run your data access layer at high speeds?

  • 1
    SQL is the most successful data access querying language. It's been constantly evolving over the past 40 years, and, nowadays, even NoSQL database systems have started employing SQL engines.
  • 2
    Do you know how the JDBC Driver executes statements and how you can configure it to boost application performance?
  • 3
    JPA and Hibernate
    Adding JPA and Hibernate annotations is fairly easy. But, do you know the performance implications of each JPA or Hibernate feature your application makes heavy use of?

What People Are Saying...

As Java developers, we all use JPA and inherently Hibernate at one point in time in our projects. Sometimes it happens that some of us just use and abuse this technology.

The presentation has the right topics, order and proper information to get the beginners and the “lost” intermediate user on the right track. You are a senior, and you wonder if it’s the right thing for you? Well, you can get under the hood and understand the underlying mechanisms and implementations used throughout the framework. Moreover, you will learn about advanced topics like caching, locking mechanisms and concurrency control.

I strongly believe that this is a great all-around training when it comes to ORM concepts.

Every time I had heard that some app needs to be fast, I would have run away from Hibernate. Well, not anymore! After attending Vlad's High-Performance Java Persistence course, I changed my mind.

It was well structured, focused on performance and day-to-day usage. There were lots of details and small things that can really make a huge difference.

Everything was backed up by code examples. Vlad is a smart guy with lots of patience, and he's passionate about technology.

Learn the power of Hibernate! Use it properly!

I've been using Hibernate for over 8 years in various projects, and I was thinking "what's more to learn about it?". Well, it turns out I was wrong. I've learned a lot after attending Vlad's training.

It was a very educative and enlightening course, backed up by a lot of code samples, answered questions, do's and don'ts in the Hibernate world. There's a huge difference between using Hibernate and using it right.

Fit to your needs

There is no limit of students that can enroll in this training. If you have multiple teams that need to attend it, the cheaper it gets per person.

The workshops can be adapted to your needs. We can even combine the agendas so that we cover exactly what you need.

All source code is provided to you during the training, so you can run the examples even after the training is done.
