I right clicked and created the catalog and the SSISDB is there but I don't see the Database Diagrams or Tables folders? What am I missing?
SSISDB isn't like a regular user database so you won't see tables/database diagram underneath it. You can right-click it and create folder, or watch operations on it. I recommend you watch one of our free webinars on new 2012 SSIS: http://pragmaticworks.com/Resources/webinars/WebinarSummary.aspx?ResourceID=424
