I am running into a little design problem....
If a bean is only changing the external structure and layout of data, should it be an entity or session bean?
The data is already persistent modeled as entity beans,
but we are only concerned about the representation of the data.
best make it a session bean, especially if the data you want to structure and layout consists of multiple Entity Beans.
yes it consists out of multiple beans, but it would be important that the data structure encapsulated in this bean is accessible by all users very fast as it is a the core element of our project.
