I'm not sure I understand what you mean but it is possible to do such things with materialized views or Streams.

Thanks Michel
just to be more clear:
on site A I have a table name t1, with this structure

site id, order id . client id, date
------- -------- --------- ----
A 1 2 22-3-09
B 1 5 23-5-09
C 3 8 12-5-09

i have the same table in all other sites B,C and D
but with data only specific to the site example:

site B:
site id, order id . client id, date
------- -------- --------- ----
B 1 2 22-3-09
B 1 5 23-5-09 B 3 8 12-5-09

so what I need is to have all this data from the 3 sites B,C and D replicate in the same table t1 in site A, real time or not it does not matter
so does oracle streams solve it ?
many thanks

Yes you can use Streams to fit this.

Many thanks Michel
but since many sites will stream to the same table at the same time, would that cause some problems on site A ? like waits...

cheers

No more than if there are several users inserting in the same table. It is database life to be accessed by many users at the same time and it supports thousand of them.
