✅ Persistence Operations with Java Persistence API (JPA).
Java Persistence API (JPA), it's a specification of Java.
JPA is used to persist data between Java objects and relational databases.
You can think of the Java Persistence API as a bridge between object-oriented domain models and relational database systems.
Persistence operations are used against the database and they are load and store operations.

In this video, we are going to explore in detail the Entity Managers and more specific we are going to learn:
- how to create the persistence.xml file
- how to create an entity and store it in the database with the entity managers
- how to update an entity with the entity managers
- how to find an entity with the entity managers
- how to delete an entity with the entity managers

We are going to use the Student entity defined in the previous video in order to create, update, find, and delete a student. During this video, we are going to use the H2 database for database operations.
