SAP HANA with SAP MDM and MDG

Hello Experts,

I am quiet new in SAP HANA. What i have got so far is that HANA provide fast access to both transactional and operational data as it is based on RAM(in-memory) rather than in disk storage.

So could anyone please help with he below scenarios:

1). How SAP HANA will help in getting fast access to the master data( i.e golden record) which is obtained from MDM.

2). How can governance policies will be implemented to the master data which is obtained from SAP MDG or SAP MDM while accesing the data through HANA.

Any help will be rewarded.

Thanks in advance

Regards

Prateek
