Spring Data JPA is a very popular data access technology, 
and knowing its inner workings can make the difference between 
a high-performance Spring application and one that barely crawls.  

In this training, we go through the most common performance bottleneck issues 
while providing the most effective solutions as well.

After this training, the students will know more about both Spring and database systems, 
so that they can better design and develop their application data-intensive applications.

Ønsker du å samle flere ansatte til et bedriftsinternt kurs?

Finner du ikke det helt optimale kurset eller kombinasjonen av kurs? Da ordner vi det - sammen. Vi kan tilrettelegge kurs slik at de inneholder akkurat det dere har behov for. Vi kan sette opp et helt nytt kurs, eller tilpasse eksisterende kurs og materiell. Flere medarbeidere kan selvfølgelig også samles til et eget felles kurs, for maksimal effektivitet. Ta kontakt med meg for et forslag til gjennomføring og et tilbud basert på deres behov.
