    HI Jiansen;

    To say this in one sentence, BW is a complete data warehousing system where ODS and MDM are structures and process within the BW to handle and manupulate the data as your business needs. Please find the detail information on http://help.sap.com/bw

    Hope this helps.

      1. You may opt to replace all those DBs by SAP BW and MDM. On service.sap.com/bw there are some presentations on the topic Enterprise DataWarehouse that go into this direction.

      A step in that direction would be to use the BW (not the MDM) as center data repository and one by one fill those databases from BW instead of the different OLTP systems. When it's time to replace the other systems you may look if you want to replace them by SAP or by other products.

      2. All master data will be synchronized in MDM, SAP and non-SAP.

      3. You should consider XI for actually transferring the data, BW for collecting and distributing transactional data and simple master data (with only one source system) and MDM for merging and cleansing of complex master data that is maintained in multiple systems.

      4. The Meta Data Model can be mapped to a subset of the CIM. But object oriented data is not a part of the BW model (apart from attributes, texts and hierarchies on InfoObjects).

      Best regards
