I was doing some cleanup of my Azure subscriptions and was going to kill one of the databases for which I am being charged. Come to find out, I am connected to two databases and both seem to be required for my site to function. Below are how they are referenced in the Web.Config file:

<!-- Connection String for SQL Server 2008/2012 Express -->
<add name="SiteSqlServer" connectionString="Data Source=qpo01e47py.database.windows.net;Initial Catalog=Sheltowee_2016-02-09T07-35Z;User ID=*********;Password=*****;Connection Timeout=600;" providerName="System.Data.SqlClient" />
<!-- Connection String for SQL Server 2008/2012
<add name="SiteSqlServer" connectionString="Server=(local);Database=DotNetNuke;uid=;pwd=;" providerName="System.Data.SqlClient" />
-->
</connectionStrings>
<appSettings>
<!-- Connection String for SQL Server 2008/2012 Express - kept for backwards compatability - legacy modules -->
<add key="SiteSqlServer" value="Data Source=qpo01e47py.database.windows.net;Initial Catalog=Sheltowee;User ID=**********;Password=********" />
<!-- Connection String for SQL Server 2008/2012 - kept for backwards compatability - legacy modules
<add key="SiteSqlServer" value="Server=(local);Database=DotNetNuke;uid=;pwd=;"/>

Why am I connected to two databases? Any help appreciated.
