Do you really need Hibernate? By Simon Martinelli

Projects often use Java Persistence API (JPA) by default and, thus, mostly Hibernate. But do all applications need a comprehensive object/relational mapping (ORM) with all conceivable functions? This talk examines the architecture of database-centric applications and discusses whether you always need an object graph for persistence. An example application shows how pure SQL, with the help of jOOQ and (nested) Java Records, simplifies data access and how common ORM problems, such as the n+1 select problem, can be avoided. Finally, the possibility of combining jOOQ and JPA/Hibernate and thus using the best of both worlds is discussed.
