ObjectDB Database Search

Hi, I have a managed database for an Entity, "Program", containing a String field, "description ... one that is contained within the System Description. public static Program programByDescription(String desc) { for(Program p : allPrograms()) if(desc. contains (p.getDescription())) return p; return null

collection contains more than 10.000 elements. There are more than 100.000 TCSteps persisted in ... entity classes. Every  TCStep will reference a new entity object that will contain the collection

Hi, I'm dealing with problem, that objectdb's log archive folder contains several other log files which are not part of objectdb. We use single location for our application log files and also objectdb log files. When application crashes or retarts, we noticed that several of our log files reside

I have an OrderData class, containing an OrderItemData collection, i would like to find OrderData elements by OrderData.items.itemId. I cant get a proper query with MEMBER OF or IN. Does anyone have an idea on how i could formulate that as Typed or CriteriaBuilder query? Thanks.   @Entity

The following JPA annotations are in use to integrate JPA into a Java EE application and are managed by the Java EE container :

This section contains miscellaneous JPA types. The PersistenceUtil and PersistenceUnitUtil interfaces provide general utility methods: The Cache interface and the CacheRetrieveMode and CacheStoreMode enum types serve in managing the EntityManagerFactory's shared (level 2) cache: Other enum types are provided for setting of various JPA operations:

JPA Entity classes are user defined classes whose instances can be stored in a database. To store data in an ObjectDB database using JPA you have to define entity classes that represent your application data object model. This chapter explains how to define and use entity classes.  This chapter contains the following sections:
