About this task
Step 2 towards the goal:
Implementing EJB 2.x applications
Procedure
You can develop an EJB application or prepare an existing
application. For Enterprise JavaBeans™ (EJB) 2.x CMP entity beans,
you can use the partial update feature to specify how you want to
update the persistent attributes of the CMP bean to the database.
This feature is provided as a bean-level persistence option, called
PartialOperation, in the access intent policy configured for the bean.
