sql server replication:
In the Books online it says : Replication is a set of technologies that
allows you to keep copies of the same data on multiple sites...
Could someone give me an answer on what is the 'set of technology' that
keeps the transactional replication running. Does it use DTS packages (or
Integrated services for 2005) or linked server at all or no. Also if there is
a good book that can explain these details, please give me some recomendation.

Thanks a lot

You can try my book in my sig.

The technologies are snapshot, transactional, and merge replication. They
use rpc and ftp, and rely on executables to read and write to and from SQL
Server.

Transactional replication reads the transaction log and writes the commands
it finds there which are marked for replication to the distribution database
which is read by a distribution agent which uses sql statements or stored
procedures to write these commands to the subscriber db.

There is a linked server involved between the publisher and subscriber.

Thanks Hilary for your responce. I did plan to buy your book, but thought if
2005 replication will be out soon, than I'd like toa have that one.
So as far as I understand from your explanation, it's both Integration
services (rpc) and linked server that play the roll. I heard that Sql2000 and
sql2005 have quite a bit of difference in the linked server approach. Would
you know how much of that is correct? Thanks again.
Best regards
Dk

Integration services does not play a role in replication.

In SQL 2000, the linked server is really a remote server call
repl_distributor. In Sql 2005 it is really a linked server.
