/**
 * Creates the department's self-relationship.
 *
 * You must first create the department and then call this class to create the
 * self-relationship.
 * The relationship is created after the parent department to avoid failures
 * when trying to create it concurrently.
 * Examples of failures that are avoided by creating the relationship after,
 * and not together with, the creation of the parent department:
 * - non-existent parent department, as the id informed for the parent does not
 * exist and will never exist (maybe the department was deactivated, but is
 * still being generated in the corporate file);
 * - non-existent parent department, because in the order of reading the XML
 * file, the parent department is after the child department being created;
 * - non-existent parent department, due to a failure in some attribute that
 * prevented it from being persisted.
