Extend your JPA applications with Relational JSON documents

Object Relational-Mapping (ORM) frameworks like Hibernate bridge object-oriented programming and relational databases, but they come with inherent limitations: complex mappings, lazy loading headaches, and gotchas like the N+1 query problem. Relational JSON documents provide an approach that combines the strengths of relational databases with the flexibility of JSON, and avoid common limitations of ORMs.

In this session, we’ll generate relational JSON document views with existing Java Persistence API (JPA) annotations, and build a demo application that uses both relational tables and comprehensive JSON documents for read-write operations.

By the end, you’ll understand:

• Common ORM challenges and pitfalls
• How to map relational tables to JSON documents for flexible data access
• Writing practical demos that integrate this approach with Spring Boot and your database
