How i do for work with objects with composition
<p>my name is aderson and in this moment i have something question about composition referents to performance.  In this model
i have a simple <strong>userbase</strong> and <strong>departmentbase</strong>. The userbase have a property of type deparmentbase and departmentbase have a list property of type departmentbase.
<strong>When i have a instance of userbase in this moment load information about department but then DepartmentBase load information about Departments too!!!.</strong></p>

<p>Now, when i have a list of userbase for all user the process load again for all users, this is a good practise or what is the better form?</p>
