Data-tier Applications feature of Microsoft SQL Azure

SQL Azure now supports Data-tier Applications which’re introduced with Visual Studio 2010 and SQL Server 2008 R2. “Here’s a quick tour feature: Launch Visual Studio 2010 and create new Data-tier Application project; Import my pubs database from local instance; Set my deployment properties to point to my SQL Azure account; Build and deploy from Visual Studio. It’s that simple! So what does this look like?

In the Data-tier Application project, the connection string is exactly same as a local instance except server name is my SQL Azure server. I select build & deploy. System built DACPAC, connected to SQL Azure instances, and deployed Data-tier Application. New database, Pubs-Azure, appears in my SQL Azure admin dashboard. Connecting SQL Server 2008 R2 Management Studio to my SQL Azure instance I see databases as well as meta-data for Data-tier Application. With VS 2010, SQL Server 2008 R2 Management Studio and latest release of SQL Azure we’ve symmetrical experience for creating, registering, & deploying Data-tier apps. Unfortunately at this time we don’t support upgrading Data-tier app on SQL Azure, as we do with on-Premise install of SQL Server. To move to your database to next version of your app you’d deploy side-by-side and migrate your data using favorite data migration tool. In addition, if you want to share database schema you no longer have to provide bunch of Transact-SQL scripts. You can give DAC Pack file, containing name of the app, version, and database schema definition. This’ll make management of apps, including deployment much simpler!,” explains Dan.
