Synchronizing data between different databases/tables

[John Hundley]

Hi,
I need to integrate two stovepipe systems and I need to synchronize a couple of tables between them. There will be two databases running on the same server. There are tables in each database that a similar but not exactly the same, each system monitors changes to it's database and behaves accordingly. What I want to do is put AFTER_UPDATE triggers on these tables and then update their corresponding table in the other database. Here is my concern, if I have an AFTER_UPDATE trigger on both tables I will get into an endless loop. Is there a way to turn off the AFTER_UPDATE triggers only during the trigger updates between the two tables?
Thanks,
John
