Comparing BW A and HANA (value preposition)

$

Hello Gurus,

 

I am looking for detailed comparison of BW A components as opposed to HANA

 

Can you please guide me in the following

 

e.g.

 

BW A (column storage) as opposed to HANA storage and compression techniques

 

BW A Blade server load distribution (how to control)

 

In BW A can we speed up loading process (i.e. from source system to BW)  OR it more of deals with Storage and Query performance

 

If we can speed up loading process, Can we directly make Data source (PSA to be on BW A) and not on normal BW server therefore the load from PSA to DSO and further to reporting speeds up ?

 

Pre - Aggregated data : In BW A, I think we still use Pre-aggregated data (tables , Indexe generations etc.).

 

In HANA we do not require Aggregates / Indexing .

 

Due to Compression techniques (Run length encoding and Dictionary encoding etc), we can reduce the amount of space used to store after compression and hence the traversing speed is dramatically reduced.

 

Things like these which can be compared...

 

many thanks

 

Krishna
