In this post, I will try to explain the context and entity terms that are used in the ORM technique in Hibernate. Also I will try to explain the basics of managing an entity within Hibernate.
In software development** persistence **is the term that refers to the information that keeps existing even after the application is not running anymore. Persistence context in Hibernate is the information related to the objects to be managed between the application and the database.
Hibernate manages the lifecycle of objects in the persistence context by being aware of their states and their relations to the persistence store. The persistence context act as a staging layer between the application and the database, once the transaction is committed in the application the changes are then applied to the database.
The managed objects in the context are called Entities. There are 4 states of entities in the persistence context.
