SQL Server is a very fine product and the best part of it is documentation. What I do in weekend is just read the documentation or some weekend project. This weekend I decided to spend on reading documentation. Earlier I downloaded and installed SQL Server 2012 Install Kit during this weekend. Honestly, quite a lot I do not understand as the documentation is quite heavy on terminologies and but that is the best part as it gives us lots of learning!
Microsoft SQL Server Data Portability Documentation
The SQL Server data portability documentation explains the various mechanisms by which user-created data in SQL Server can be extracted for use in other software products. These mechanisms include import/export functionality, documented APIs, industry standard formats, or documented data structures/file formats. There are additional documentations available on Book On Line for further reading. Microsoft is providing access through open connections to its high-volume products—Windows Vista (including the .NET Framework), Windows Server 2008, SQL Server 2008, the 2007 Microsoft Office system, Microsoft Exchange Server 2007, and Microsoft Office SharePoint Server 2007—so that software developers, business partners, and competitors can better interact with these Microsoft products or invent new solutions for customers.

Microsoft SQL Server Protocol Documentation
The Microsoft SQL Server protocol documentation provides detailed technical specifications for Microsoft proprietary protocols that are implemented and used in Microsoft SQL Server to interoperate or communicate with Microsoft products. The documentation includes a set of companion overview and reference documents that supplement the technical specifications with conceptual background, overviews of inter-protocol relationships and interactions, and technical reference information.
