/* HISTORY:

   81-01-28 Jim Gray : originally created for the mmi_$get_model_attributes interface.


*/

/* DESCRIPTION:

   This structure returns, for a given relation, the list of all attribute names in
   the database model. A count of the number of names present is included.
   No submodel alias names for the attributes are involved.
   Also, the domain name, and the users view descriptor for the data type
   is returned, as well as a bit indicating whether the attribute
   can be used as if it were indexed or not.
   This structure is to be used externaly, not internal to MRDS.

Historical Background

This edition of the Multics software materials and documentation is provided and donated
to Massachusetts Institute of Technology by Group Bull including Bull HN Information Systems Inc. 
as a contribution to computer science knowledge.  
This donation is made also to give evidence of the common contributions of Massachusetts Institute of Technology,
Bell Laboratories, General Electric, Honeywell Information Systems Inc., Honeywell Bull Inc., Groupe Bull
and Bull HN Information Systems Inc. to the development of this operating system. 
Multics development was initiated by Massachusetts Institute of Technology Project MAC (1963-1970),
renamed the MIT Laboratory for Computer Science and Artificial Intelligence in the mid 1970s, under the leadership
of Professor Fernando Jose Corbato. Users consider that Multics provided the best software architecture for 
managing computer hardware properly and for executing programs. Many subsequent operating systems 
incorporated Multics principles.
Multics was distributed in 1975 to 2000 by Group Bull in Europe , and in the U.S. by Bull HN Information Systems Inc., 
as successor in interest by change in name only to Honeywell Bull Inc. and Honeywell Information Systems Inc. .
