Hi,
Please have a look at document EDW. Here you can find an overview with links to useful resources, blogs, documents and presentations.
Although a custom Enterprise Data Warehouse using native HANA could be an alternative, many customers running SAP source systems can take advantage of a lot of BW on HANA functionality (incl. Business Content, even optimized for SAP HANA).
I would like to share a couple of links to blogs and documents where experts share their opinion re. this topic.
