How does synching between sql server and sql azure databases work if I use Sync Framework?
Does it have a master-slave rule? Or
Does it send bidirectional data in between connection and appends changes to one another?
回答1:
it's up to you, you can hub-spoke (master-slave) or peer-to-peer... you can do upload only, download only or bidirectional.

and if you want an n-tier setup, have a look at this one as well: Walkthrough of Windows Azure Sync Service Sample
Or if you want an out-of-the-box sync solution, have a look at the Azure SQL Data Sync Service
