Question

I have 2 databases that have the same structure, one on a local machine and one on the company’s server. Every determined amount of time, the data from the local DB should be synchronized to the server DB.

I have a general idea on how to do this – create a script that somehow “merges” the information that is not on the server DB, then make this script run as a scheduled job for the server. However, my problem lies in the fact that I am not very well experienced with this.

Does SQL Server Management Studio provide an easy way to do this (some kind of wizard) and generates this kind of script? Is this something I’ll have to build from scratch?

I’ve done some basic google searches and came across the term ‘Replication’ but I don’t fully understand it. I would rather hear some input from people who have actually done this or who are good with explaining this kind of stuff.

Thanks.

Answer 1

Replication sounds like a good option for this, but there would be some overhead (not technical overhead, but the knowledge need to support it).

Another SQL Server option is SSIS. SSIS provides graphical tools to design what you’re trying to do. The SSIS package can also run SQL statements, if appropriate. An SSIS package can be started, and therefore scheduled, from a SQL Server job.

You should consider the complexity of the synchronization rules when choosing your solution. For example, would it be difficult to resolve conflicts, such as a duplicate key, when merging the data. A SQL script may be easy to create if the rules are simple. But, complex conflict rules may be more difficult to implement in a script (or, replication).
