Differences in the Directions Kotlin and JPA Pursue

Are you aware that Kotlin and JPA pursue different directions?

Let's explore why Kotlin and JPA pursue incompatible directions.

The Direction Kotlin Pursues #

Kotlin aims for immutability, striving to enhance code stability by minimizing mutable states.

To achieve this, you can declare variables using the val keyword and define immutable data models using data classes.

The Direction JPA Pursues #

In contrast, JPA is designed around mapping objects to a database, with its primary goal being to change the state of the database.

Therefore, JPA defines mutable data models using entity classes and interacts with the database using EntityManager.

Conclusion #

Kotlin and JPA pursue different directions regarding the mutable state of objects.

It would be best to use them considering their respective pros and cons. -> Separation of Domain and Entity
