+/**
+ * @author ebk2fe
+ * @version 1.0.1 June 9th, 2006
+ *          <p>
+ *          This test case creates a writer object and assigns a typewriter to the writer. The object model uses a 1:n
+ *          association based on EList to store the reference from writer to the typewriter(s). The data base model
+ *          provides an associative table to cover the list of references. The or-mapping uses the many-to-many mapping
+ *          to implement the 1:n relationship. The benefit would be that no explicite backward reference is required at
+ *          the object model.
