Microsoft's new data platform vision for BI is called BISM – Business Intelligence Semantic Model.  While I focus primarily on manageability, availability and database engine features, I'd like to keep tabs on who can help you out with their input on the other aspects I rarely touch – Analysis Services (SSAS), Integration Services (SSIS), and Reporting Services (SSRS).  Since I'm not covering these areas in my "What's New in Denali" presentations, I thought it would only be fair to provide a decent launch point So here are some blogs, individual posts and other resources with great information – if you have any other resources, please let me know!  Here is what I have come up with so far, in no particular order:

Jen Stirrup has some thoughts on BISM that are definitely worth a read:

Chris Webb also talks about BISM and its unification with SSAS:

The AS & PowerPivot team blog also has some information about BISM and SSAS:

Rafael Salas talks about a lot of SSIS topics as they relate to Denali:

Robert Bruckner of the Reporting Services team answers many questions about Project "Crescent":

Chris Webb lists some great talking points about SSAS, with some excellent comments as well:

TechNet Wiki has some great stuff on SSIS enhancements in Denali on the new SSIS Catalog ("SSISDB") and usability enhancements:

Jacob Sebastien has created a "What's New in Denali" resource page that has plenty of BI-related information:

Watching the Denali tag on this site could be useful, even though most of the posts so far do not relate to BI:

While during CTP periods, Books Online is rarely in sync with the actual build that is out there, it can still contain quite a bit of information.  Here is the starting point for "What's New" in Denali:

And you can download the latest "offline" version of Books Online here:

The official SQL Server "Denali" site – more marketing than tech, but still useful:

And here is MSDN's Denali Resource Center:

If you're looking for help, the SQL Server community is a vast and generous resource. Post your question under the appropriate twitter hashtags:
