transactional - Distributed Transaction or not -

-

i'm implementing code access remote sql server 2005 database , updates 2 tables in transaction. confused whether distributed transaction or not?

because definition, distributed transaction occurs when update data on 2 or more network computer systems. in case code in single application domain , access , updates 1 durable resource manager. can't local because database remote. please advice.

distributed transactions when 1 remote system / db queries another.

you querying single remote data source not distributed.

do aware however, remote queries don't appear distributed may under hood.

e.g. query view on remote source, , view queries 1 or more other remote db's. has caught me out few times!
