What is SAP HANA ? SAP HANA is the latest in-memory analytics
product from SAP; using HANA companies can do ad hoc analysis of
large volumes of data in real-time.In-memory means all the data is
stored in the memory (RAM). This is no time wasted in loading the
data from hard-disk to RAM or while processing keeping some data in
RAM and temporary some data on disk.
www.arkansys.comWhat is real-time analytics?Using HANA,
companies can analyze their data as soon as it is available. In
older days, professionals had to wait at least few hours before
they could analyze the data being generated around the company. SAP
making/selling the software or the hardware? SAP has partnered with
leading hardware vendors (HP, Fujitsu, IBM, Dell etc ) to sell SAP
certified hardware for HANA. SAP is selling licenses and related
services for the SAP HANA product which includes the SAP HANA
database.

www.arkansys.comIs HANA really fast?How is it possible that HANA
is so fast? HANA is fast due to many reasons. The following picture
1 depicts a very simplified version of whats inside the In-memory
Computing Engine.Column Storage While the traditional databases
store the relational table one row after another, IMCE stores
tables in columns. Hopefully the following figure explains the
difference between the two storage mechanisms easily .
www.arkansys.comCompression:As the data written next to each
other is of same type, there is no need to write the same values
again and again. There are many compression algorithms in HANA with
the default being the dictionary algorithm, which for example maps
long strings to integers.Example of dictionary algorithm: You have
a Country column in your Customer table in your database. Lets say
you have 10 million customers from 100 countries. In the standard
row-based storage you will need 10 million string values stored in
memory.
Parallel Processing:It is always performance critical to make
full use of the resources available. With the current boost in the
number of CPUs, the more work they can do in parallel, the better
the performance. The columnar storage enables parallel processing
as different CPUs can take one column each and do the required
operations (aggregations etc ) in parallel. Or multiple CPUs can
take a partitioned column and work in parallel for faster
output.
