Course Description
Have you heard an opinion that applications using Hibernate are slow? For sure you did! I have heard that as well. And it is often true.
Fortunately, that are some simple actions that you can take to speed it up. You just need to understand how a database engine works and how Hibernate uses it, then you can build efficient high performing Java applications.
In this course, I will teach you the most important aspects of database engines' performance - I will use MySQL, but these rules apply to most relational database engines: SQL Server, Oracle, and PostgreSQL. I will give you important tips and tricks on how to solve common performance problems with Hibernate.
Don't let your next Java app be slow, enroll in this course now.

Instructor Details
Arkadiusz Fronc
I am a passionate fullstack developer. I started as a database developer in 2005. In 10 years I mastered database design performance tuning and data migrations. I wanted to gain more skills and I became a web applications developer coding in Java technologies like Spring and Hibernate. I extended the field of my interests by frontend technologies like JavaScript and Angular.
I believe I have a unique combination of skills: database, backend and frontend which makes me a valuable consultant and instructor.
