How to get started with SBO

Hi,

I am a newcomer to this forum. Although, my knowledge is mainly limited to SAP R/3, I like advice on how to get started on SBO? Appreciate if someone can help with the following:

1. Do I need to purchase SBO before I can get started? if yes, what version?

2. What is the minimum license requirements?

3. What platform is SBO most commonly running on.

4. Does SBO work with Netweaver?

That's all for the time being.

Thanks and regards
