Relation between SAP BI, BPC for NW, Business Objects

Hi,

Iam an experienced SAP BI consultant. These days I see the terms BPC and Business Objects integration with BI. I understand many clients too are interested in these new applications.

I want to understand how BPC for NW is integrated with BI? Is it an add-on or a separate installation? I saw some documentation available in help.sap and SDN but not any information related to installation. post any info related to this?

How is BPC related with Business Objects? Does a BI consultant can use BPC without knowledge of BO's? Or BO knowledge is required to work wth BPC?

Iam confused. Clarify.

regards,

S R
