A new week, and a new competitor. Norwegian company BI builders has popped into view with a very pretty looking dimensional warehouse solution for SQL Server users.
It is a desktop solution, generating SSIS, which puts it in the same category as Dimodelo, TimeXtender and (perhaps) WhereScape. LeapfrogBI is a little different, being a web-based solution.
This is becoming a very competitive section of the market!
