Persistence

This chapter introduces the Persistence Configuration Editor and the Persistence API of Axon Ivy. The persistence framework is based on the Java Persistence API, a.k.a. JPA) and provides support for storing and loading business objects from and to a database.

To use automated persistence in your business or User Dialog processes, you need to define Entity Classes first. An entity class is similar to a data class (i.e., a business object) but holds additional information that is used to map the class to a database table and its attributes to database table columns.

You need to define at least one persistence unit configuration. A persistence unit manages all or a subset of your entity classes and defines the database where those entities are stored. Once you have configured one or more persistence units, you can use them in your process steps with the Persistence API to load/update entity objects directly from the database or save and update them in the database.
