With no previous database experience you should maybe expect your employer to provide some training.

However, there are some reasonable tutorials available online. But learning to handle BI related products from online tutorials when you don't have significant experience in the area is a rather heavy task unless your employer is going to provide someone to spend quite a lot of time acting as your mentor and helping you to learn.

A good place to start looking is the Microsoft on-line documentation, which includes on;ine tutorials. For SSAS you could start from http://msdn.microsoft.com/en-us/library/hh231701, for SSIS from http://msdn.microsoft.com/en-us/library/ms167031%28v=sql.105%29.aspx and also from http://msdn.microsoft.com/en-us/library/aa337424 and from http://msdn.microsoft.com/en-us/library/bb522859.aspx, but these do require some basic knowledge of SQL Server and MS's various development studios, plus access to a computer with the software you are learning about installed. The underlying database system on which SSAS, SSIS, and SSRS (you can't do really BI without SSRS) are founded has some tutorials starting from http://msdn.microsoft.com/en-us/library/jj590844.aspx and you may find that you have to look at some of this in order to understand the stuff I mentioned before.

The references I've given above are mostly for the 2012 versions - and I see you've posted in the 2008 forum; they pages referenced contain links to earlier versions, so you can follow those links and get the version you need.
