4. Introduction to SAP HANA
SAP HANA is
a flexible, data-source-agnostic appliance that enables
customers to analyze large volumes of SAP ERP data in real-time,
avoiding the need to materialize transformations.
In-memory database
It supports analytical and transactional applications.
It supports relational data as well as graph and text
processing for semi- and unstructured data
It is “ACID” compliant.

The elements of In-Memory computing are not new. However, dramatically improved
hardware economics and technology innovations in software has now made it possible for
SAP to deliver on its vision of the Real-Time Enterprise with In-Memory business applications
HW Technology Innovations
Multi-Core Architecture (8 x 8core
CPU per blade)
Massive parallel scaling with many
blades
64bit address space – 2TB in current
servers
100GB/s data throughput
Dramatic decline in
price/performance
SAP SW Technology Innovations
Row and Column Store
Compression
Partitioning
No Aggregate Tables
Real-Time Data Capture
Insert Only on Delta

6. Processors are more powerful with hyper
threading and higher clocking speeds thus
offer higher throughput
Also processors come with multiple processing units
( multi cores)
Multi CPU Boards per server
Multi server boards
For ex: Nahelms – 4 cores
Dunnington – 6 cores

organize by row
organize by column
Columnar layout supports sequential memory access.

11. A partition is a
division of a logical
database or its
constituting elements
into distinct
independent parts
Horizontal
partitioning
Vertical
partitioning
TABLE

13. Columnar database allows basic data compression
by removing redundant data.
Run-length encoding
Also, there are several other compression
algorithms with which data can be lossless
compressed..Eg: dictionary encoding, bit vector
encoding

17. SAP Other in-memory appliances
Business Warehouse Accelerator
BO Explorer Accelerated
CRM Segmentation
SCM Live-cache

18. SAP HANA
Supports any data
sources.
Supports
transactional and
analytical processing.
Supports row-store
and column store.
It’s a faster RDBMS.
SAP BIA/BWA
Supports only data
from BI for faster
reporting purposes.
Not an RDBMS.
Supports only column
store using TREX flat
files.

19. SAP HANA Components
SAP HANA DB (or HANA DB).
SAP HANA Studio
SAP HANA Appliance refers to HANA DB as
delivered on partner certified hardware (see
below) as an appliance.
 SAP HANA Application Cloud refers to the
cloud based infrastructure for delivery of
applications (typically existing SAP applications
rewritten to run on HANA).

20.  SAP HANA appliance software is a hardware and
software including the
SAP HANA database,
SAP LT Replication Server and other available
replication technologies.
