Editing a File Geodatabase

[GunnarOlson]

Hi. This is a relatively simple question...I just need clarification. I just read "The Top Nine Reasons to Use a File Geodatabase". I downloaded the pdf, but the same info was published in ArcUser - Spring 2009. Reason 4 states that File and Personal GDBs are designed to be edited by a single user, YET Reason 5 states (about File GDBs) that "Stand-alone feature classes, tables, and feature dataset contents can be edited by different editors simultaneously without the entire geodatabase being locked". 

Is there not a serious contradiction here?!? Am I reading this wrong? Can someone clarify for me?

Thanks!!

Both personal geodatabase and file geodatabase use a single editor model, but differ on the level of implementation. In a personal geodatabase the entire geodatabase is locked to one editor. In a file geodatabase the locking is at the feature class, table and feature dataset level. Each feature class and table at the root level can be edited by a different editor. The feature classes in a feature dataset can only have one editor.
