Data-Tier Applications of SQL Server 2008 R2 make
database development, deployment and management much easier. When you create a Data
Tier Application and build it, it creates a single, self-contained unit of
deployment called a DAC package in compressed format that contains SQL Server
instance objects that are associated with the database, database objects and
In my last article “Creating Data-Tier Applications in SQL Server 2008 R2” I gave you an overview of Data-tier applications, then I
talked about how it differs from database projects and finally I showed how you
can create a DAC package using Visual Studio 2010 and SQL Server 2008 R2
Management Studio (SSMS). In this article my focus is to deploy the created DAC
package and discuss the different methods of deployment.
A DAC package is very much like the Windows installer
MSI file of any application that contains everything required for deployment. You
can deploy a created DAC package to an instance of SQL Server 2008 SP2, SQL
Server 2008 R2 and SQL Azure by either using:
Studio 2010 Premium, Professional and Ultimate editions
Server 2008 R2 Management Studio
Deployment using Visual Studio 2010
Studio 2010 Professional, Premium and Ultimate editions allow you to create
Data Tier Applications; you can find a feature list, listed by edition, at Microsoft
Data tier application allows you to declare deployment
intents, which are nothing but the pre-requisite checks before deployment. To
define the deployment intent, double click on the ServerSelection.sqlpolicy
file under Properties in Solution Explorer as shown below.
Figure 1 – Defining Deployment Intents 1
policy page allows you to define different policies (intents); for example, I
only want to deploy my data tier application on SQL Server 2008 (Version: 10)
and higher and this is what I have declared as you can see below.
Figure 2 – Defining Deployment Intents 2
policy selection page allows you to include as many as intents you want to be
included with your DAC package; those added intents will appear in the bottom
section of the page as shown below.

deploy your DAC package, right click on the project in the solution explorer
and click on the Deploy menu as shown below. The deployment actually includes
building the DAC package from the project and then deploys it on the specified

you can deploy the project by clicking on the Deploy Solution submenu under the
Build menu as shown below; if the project is open in the IDE (Integrated

am using the same Data-tier application that I created in my last article “Creating
Data-Tier Applications in SQL Server 2008 R2” for deployment. When
I tried deploying the build it failed because I didn’t specify the target SQL
Server instance where the DAC package is to be deployed, (see the highlighted
part in the below image).

define the target connection string for deployment, right click on the project
in the Solution Explorer and then click on the Properties menu. In the project
properties screen select Deploy on the left and click on the Edit button to
specify the target connection string as shown below.

you have defined the correct target connection string, try to deploy again. This
time it will pass and you can monitor the Output window for deployment status.
