 249 | The term persistable types refers to data types that can be used in storing data in the database. ObjectDB supports all the JPA persistable types, which are: User defined classes - Entity classes, Mapped superclasses, Embeddable classes. Simple Java data types: Primitive types, Wrappers, String |

But more often they are used in JPQL path expressions that navigate to values of simple types (number, boolean, string, date). Simple type values are more useful in queries. They have special operators |
