SQL Database Mirroring Between Sites

We have some EMR software which uses mssql server as the backend and there are issue with speed over a WAN connection. So I have a thought of placing a server at this remote site and doing replication between the two sites. They need to pretty much mirror each other.

Does anyone have some guides on best practices for setting this up?

Are both ends going to be updated at the same time, or is one end going to get the updates and the other only be used for reporting? To start off with I'd delve into the Microsoft docs: one-way transactional replication, where you have amain machine and a secondary that gets the changes but doesn't initiate new stuff itself here, and bi-directional replication, where changes happen at both ends, here.

We need them to both be active and keep each other in sync because changes will be made at both.

So my second reference above applies. Look also at Hilary Cotter's blog post on the subject here (get to see him - he's a great speaker - he was at the Philly SSUG meeting last night!).

So with his article, is this the framework of the replication, and can be applied to any kind of database you are using? I already have the emr software setup within this so I'm wondering if I can apply these practices to it.

Normally you would work with the producer of your application software - it would be a large risk to arbitrarily change the database system that your application depends on. It might work, but it might also lead to the software expecting something and not finding it and crashing ...

I don't offhand know what you mean by "EMR", but I would be very loathe to alter the database system any third-party application depends on!
