SAP BO 4.0 Dashboard connectivity with google analytics

Hi

To all,

I Have a question regarding how to connect the google analytics data to dashboard through the web services connection,

I haven't try this web service connection yet before.

I have serached on net, and i get some link, which shows

> embedded API.

>Configure Google Analytics Account

But I want,

1> WSDL Url so that I can connect with web service URL.

OR

2> How to fetch Data in any RDBMS OR in webi?

thank you,

Swati
