Interaction between tables of local and remote SQL databases

Hi all,

I would be very glad if someone can suggest me what techniques I should use in the following scenario:

I have 2 SQL Server databases : DB1 and DB2. DB 1 is on a remote server (hosting server) and DB 2 is on a local server.

Some tables of each db contain tables that are polulated and changed by the appropriate application, i.e.:

DB1.users, DB1.orders,... etc are managed by "webapplication"

DB1.products ... are not managed by "webapplication" : in fact only used to read from

DB2.products, DB2.customers, .... etc are managed by "winapplication"

DB2.orders,....are partially managed by "winapplication"

Since the amount of data can go over 100000 records i'm wondering what would by the best approach to :

- synchronize the data of DB1.products and DB2.products in DB1 on remote server (updated newly added rows and update changed rows,....)

- the products data is only (at the moment) added, edited and deleted on the local server

I think SQLBulkCopy will not do the job. Should it be possible with some query? Or...?

Any suggestions are appreciated!!

Some addition:

- Does SQLBulkCopy copy-append data to the destination database.table?

- What about identity keys?

- Should it be the best solution to modify the SqlCommand so it takes only those rows I want to be inserted as (depending on bulkcopies already done before) or is this done by SQLBulkcopy itself....?

Please inform.
