SQL3
     
         A draft {standard} for another
        extension of {SQL}.  The latest SQL3 Working Draft addresses
        the requirement for {object}s and "object identifiers" in SQL
        and also specifies supporting features such as
        {encapsulation}, {subtype}s, {inheritance}, and
        {polymorphism}.
     
        In the USA, SQL3 is being processed as both an {ANSI} Domestic
        ("D") project and as an {ISO} project.  It is expected to be
        complete in 1998.
