Here’s the webcast I did (around 60 minutes) on the new BISM in SQL Server 2012 — enjoy!
Here are the slides on slideshare as well.
Are you using the BISM in production yet? I’d love to hear how it’s working out for you. Share insights as comments on this blog post or questions about the BISM functionality on Stack Overflow (use the tag ‘SSAS‘ on Stack Overflow to post / search)
