i created a post earlier in regards to refreshing a materialized view. i saw that i am able to do a refresh fast on my materialized view but you have to have a materialized view log ...
and does anyone know if a refresh fast copies all of the data from the master tables or does it only copy the new entries ??

my question is: i have to do an update on 27 tables ...
so i have to create 27 logs on each of the master tables ...

does this somehow affect performance ... ??

is there a better way to do it ??

is it possible to create a materialized view without the refresh option - never - and create a trigger which would update the materialized view ... ( if i was to create a trigger, you would apply the trigger on all 27 tables, RIGHT ??? )

help would be appreciated ...

merry xmas and a good slide into the new year ...
