1) If the wcf service is performing insert in table of one sql server database and delete from table of another sql server database(In same or different server)
2) If the same wcf service is performing insert in table of one sql server database and delete from table oracle database.
3) If wcf service calling 2 different wcf service performing operation on same sql server base database.
