mqt is always mqt
maintained by system immediate / deferred / refresh
as I understand : maintained by user : the user executes the "refresh" whenever needed
the refresh command is not supported for user mqt
User-maintained MQTs do allow insert, update, or delete
you create a query table based on the layout of base table and will be accessed directly.
for mqt : the user does not know the mqt and always uses the base table - if needed/possible the system will route the query to the mqt

Good DBAs are not formed in a week or a month. They are created little by little, day by day. Protracted and patient effort is needed to develop good DBAs.
