Hi
I have a table of 1 million records. and it is having around 5 child tables also. I created 8 indexes on my parent table as while tuning i found that it is in need of that much indexes. As of now the performance also quite satisfactory. Will this reduce the performance if the no. of records increased???
could anybody give me the answer asap?
Thanx in Advance

Adding indexes to a table will:
*** Increase performance on queries
(Don't forget to tune SQL statements)
*** Decrease performance on DML statements
- INSERT, UPDATE, DELETE

Hi,
As your indexes are on master table which would not have frequent inserts , I dont think the performance will go down if records are added to child tables.
Take Care.
