But are you sure that this method (Transactional publication with updatable subscriptions) makes update conflict


The method doesn't make them, your application (modifications) may cause conflicts.

why SQL 2008 contains this method if there is a problems when we use it


For example: you have the same row on two different SQL Servers which then replicate the modifications to each other. The replication interval is, let's say 15 minutes. Now you update the same record on both SQL Server. Next time the modifications are replicated, SQL Server sees that the exact same row has been modified on both ends. Now the question is, which modification is correct? There's no simple answer to that. In some cases it may be the earliest or the latest or perhaps it's both modifications combined.

So the problem isn't in the technology. It is something that you as a designer must be aware of and model the data and the applications so that conflicts do not occur or that they are rare.

The same conflict situation concerns all modifications (update, insert and delete).

what is the ideal solution for making replication in SQL server 2008?


This depends fully on the requirements.

The need to optimize rises from a bad design.My articles[^]
