Abstract class
Instances of this class identify a user to a DBMS. It is the root class of all user classes, and a subclass of <object>.
The user: init-keyword takes an instance of <string> that should be a valid user name for the DBMS in question. The password: init-keyword should be the password that accompanies the user name.
If you apply make to the class <user> within the scope of the with-dbms macro, an instance of a DBMS-specific user class is created.
The SQL-ODBC library defines a class <odbc-user> for identifying a user to an ODBC DBMS.
