I'm in the process of designing a system which is fairly large. Its a kind of system with multiple installation.

The design is as follows

1. Main Server & Application at the Head Office(HO) - This hosts all the data and the Web App.
2. A small Server and Application at the Branch Office - Ideally the users at the branch site will logon to the HO App and do the Processing. The problem is that the Net connection is not reliable and might be out for hours together. To over this the App will be installed at the Branch office with local DB (this will be a subset of the Main DB and will contain the data that pertains to the specific branch).

The master entries will be created only at the HO.

The query is.
What is the best way to synchronize the data between HO and branch? The master data needs to be pulled from the HO as and when created and the transaction should be pushed to the server (whenever the internet connection is available).

Database (HO): SQL Server Standard (2008)
Database (Branch): SQL Server Express (2008) (as we assume that the data volume will be less).

We use SAN replication over a dedicated line. I'm not sure how it works but the folks in NetOps have it absolutely screaming.

Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column."
