Gayaneh Posts: 40	Posted 10:49 Oct 28, 2012 \| When I have relations such between Project and Advisors, Resources,... how should we construct those objects when we query from database? For example for fetching one project we query projects table. I was thinking that it should construct the lists of Advisors, Resources, etc. using the relations between those table automatically... :) But i think I am wrong and I have to build those lists by by querying their corresponding tables... Is this is the right way to go? With thanks in advance. Gayaneh

You just need to query for Project. When you access something referenced by an object, e.g. project.getAdvisors(), they will be loaded automatically from the database by Hibernate.
