                             Stereotype  | 
                        
                             Sub-classification used to extend the semantics of an object without changing its structure; it can be predefined or user-defined  |

                             Owner  | 
                        
                             Name of the synonym owner. You choose an owner from a list of users. A synonym can only have one owner at a time  | 
                    
| 
                             Base Object  | 
                        
                             Name of the object origin of the synonym. The Ellipsis button displays a selection dialog box that lets you select objects among all the models opened in the current workspace and belonging to the same DBMS family as the current DBMS  |

                             Visibility  | 
                        
                             Allows to define a synonym as public (accessible to all database users) or private (available to a specific user)  | 
                    
| 
                             Type  | 
                        
                             For those DBMS that support it (for example DB2) you can create an alias instead of a synonym. In PowerDesigner synonyms and aliases are managed in the same way whereas their behavior in the database may be different  | 
                    
For more information on aliases, see the DB2 documentation.
