JPA with Spring Boot
JPA is one of Java's persistence frameworks in order to access relational data in an effective way. It offers a complete object-relational mapping solution to this end. Spring Boot will help you making it even more efficient, by adding JPA repositories, and by simplifying the configuration.
The purpose of this course is to show the participant how a Java application can be mapped to a relational database schema with the use of Spring Boot and JPA.
Schedule
Momenteel zijn er voor deze cursus geen publieke sessies gepland. Graag organiseren we een bedrijfssessie voor u of een extra publieke sessie (bij voldoende belangstelling). Geïnteresseerd? Laat het ons weten.

Reviews
trainer was well prepared. course and content was very useful. issue was with the vm being slow which slowed down the pace and killed the mojo.
