The Best Way to Map Entities with Java Persistence and Hibernate

This online workshop was given on the 25th of June 2020

Hibernate is the most popular JPA provider and knowing its inner-workings can make the difference between a high-performance enterprise application and one that barely crawls.

Based on my book, High-Performance Java Persistence, this online workshop is meant to mind the gap between Java developers and database programming.

Agenda

In the next webinar, I'm going to present The Best Way to Map JPA and Hibernate Entities.

Therefore, we are going to discuss:

  • What are the basic entity types and how to choose column types for best performance
  • How to use database-specific column types like JSON, ARRAY, HStore, Inet, and more
  • What are entity identifiers and what auto-generation strategies are offered by JPA
  • What are Hibernate natural identifiers
  • How the Hibernate sequence optimizers work
  • Why you should avoid the TABLE GenerationType strategy
  • Database table relationships (e.g., one-to-many, one-to-one, many-to-many)
  • How does the JPA @ManyToOne relationship work
  • How does the JPA @OneToMany relationship work
  • Unidirectional vs. bidirectional @OneToMany collections
  • How to synchronize both sides of a bidirectional association
  • How does the JPA @ManyToMany relationship work
  • How to map additional columns for a @ManyToMany relationship

Target audience

This workshop is for any Java developer that happens to develop software that interacts with a relational database system.

After watching it, you'll know all sorts of tips that you can readily apply to your current enterprise project.
