Hi, I want to certify myself on the Microsoft BI Platform and plan to study for the 2 required exams (70-445, 70-446) that define the MCITP for Business Intelligence Developers. I needed to know whether it is absolutely mandatory for me to give the MCTS in SQL Server 2005 (70-431) in order for me to be adept enough at attempting the MCITP or can i go ahead and start studying for exam 70-445 directly. I have worked with SQL Server 2005 from a simple ASP ..NET 2.0 programmer for a while now. Kindly help me out here someone, Thanks
