DBA_HIST_SEG_STAT and database growth
Hello, I am trying to look at what degree our 11G database is growing on a weekly basis, I believe DBA_HIST_SEG_STAT is the table to look at, I have come across queries that use one of the following columns
SPACE_ALLOCATED_DELTA
SPACE_USED_DELTA
Can somebody explain the difference between these columns, and which one I should be using?
Thanks
