Tips on planning SQL for System Center 2012
I think many of us have faced the challenge to make the design of SQL for their System Center components. Even though we have knowledge of SQL at some certain level we are not hardcore experts in it. Thanks to Paul Keely a Microsoft MVP we now have some guides on dealing with SQL for System Center. You can download his guide
“SQL Server guide for System Center 2012” which for SQL 2008 R2 but there is no reason to use the same tips for SQL 2012.

System Center 2012 Integration Guides
With System Center 2012 the different products of the family became components. This was not just changing of words. This change has the goal to tip that all components come in one license and that their integration is way better compared to the previous versions. To help us leverage that integration community project created Integration guides for System Center 2012 components:
The purpose of the Integration Guide is to provide an overview of each System Center component in its role as a programmable platform to be leveraged for the Microsoft Private Cloud. It is intended to provide an abstraction layer that guides partners and customers on their decision process for methods to build automated solutions across System Center components and between System Center and other systems.
