 <p>
 Just for convenience, if the type name is not full qualified, it will be
 prepended by the "&lt;DATABASE_NAME&gt;.&lt;USER_NAME&gt;." string.
 Anyway, it is strongly recommended that you use <b>only </b> full
 qualified type names. The rational for this is that the actual ArcSDE
 name of a featuretype is full qualified, and more than a single type
 can exist with the same non qualified name, if they pertein to
 different database users. So, if a non qualified name is passed, the
 user name which will be prepended to it is the user used to create the
 connections (i.e., the one you specified with the "user" parameter to
 create the datastore.
