Difference Between SAP BI AND SAP BO

1.  The BW is more like a Datasource for BO.
   A logical Datasource for BO.
   A RDBMS (f.e. Oracle, MS SQL...) dont has to be a logical
   Datasource, its only a relational Datasource.
    On these Datsources you have to build the Logic on top
   with a Universe f.e.
2. BO isnt a Datasource.
    BO are analytical tools for your Datasource and
   BW can be such a Datasource.
3. At the end the BO tools are on top of your Datasource.
    No matter if a OLAP (f.e. BW) or
   a RDBMS (f.e. Oracle, MS SQL...) Datasource
