Design Studio 1.3 BIP Question

Hi All,

I have installed  Design installed 1.3 ,and I have a question.

We have 4 components while installing Design studio: .

1. DS1.3 BIP Add on

2. DS Client

3. DS HANA Add On

4. DS BW add on

So if I want to design applications on BW do I need to install , BW Add on on BW server? or If I have just the BIP add on and design studio client installed, can I create applications on BW?

Whats the purpose of Hana and BW add ons?

Regards,

RVS
