System landscape - SAP BO BI onDemand

Hi,

I am unable to find any documentation related how the system landscape is set up in SAP BO BI onDemand.

From the getting started documentation I understand that all the development is done on the web. Does this mean all dev will be done in a development enviroment, transported accross to QA and then to Prod?

Or is this kind of create and use type of environment.

Thanks a lot in advance for clarification.

Thanks,

Sandeep
