BW will be still needed when HANA using?

Question

Hi Experts,
Is HANA replacement for relational database? What support and maintenance for such database? what application that can use HANA, OLTP,BW,SCM,CRM? Is HANA same with BW/BI Accelerator? HANA appliance may be addition or plug in to existing traditional database which used for reporting and query purpose which 3600x faster transaction than traditional database query. HANA may also replace OLAP/BI/BW requirement for certain function? Is HANA also replacement for BI Business Object in future? BW will be still needed when HANA using?

Answer 1

"Will HANA eliminate the need for BW?
This is a question that surprisingly keeps creeping up from all
sides and customers. However, we can only see so far ahead. My
current statement will be not for the next five to eight years
based on two basic myths that must be bust right now:
1. If we take all the ERP fields into a data warehouse, or an
appliance, we should then be able to answer every
question.
a. This is a myth that is still prevailing in the data
warehouse world. It is most applicable to the
Accelerated Explorer and now to Hana. Not
considering this will result in a costly mistake. All data
can answer is simple questions. However, large
organizations do not live by simple answers alone.
Data filled appliances cannot answer complex

Release 1.0 of HANA is for non-disruptive and very fast
Operational Reporting. Operational reporting normally
consists of simple reports and to meet day-to-day
reporting needs.
b. HANA version 1.0 is for ECC data access only
c. HANA leverages existing technologies of BW
Accelerator, BusinessObjects Explorer and
BusinessObjects WebI along with Sybase database to
deliver real-time informatics in critical areas. The key
here is critical areas and how business defines this
singularity for using HANA.
d. Data warehouses enable complex transformations,
summarizations, exceptions and a host of other
filtering that enables a u2018SPOTu2019 (Single Point of Truth)

executives need answers to complex questions data
warehouses will remain u2013 unless of course we get a self

demand and consumption."
