 Key takeaways about HANA


[ What is SAP HANA?

 SAP HANA is the latest in-memory analytics product.
Using HANA, companies can do ad hoc analysis of large
volumes of big data in real time

 SAP HANA is a completely re-imagined platform for
real-time business

 SAP HANA transforms businesses by streamlining
transactions, analytics, planning, and predictive data
processing on a single in-memory database so
business can operate in real time

[ Why the Need for SAP HANA?
IT Challenges:
 “Big Data” (volume) growing and challenge for
real-time access to Operational Enterprise Systems

 Costly for IT to purchase and maintain hardware to handle
increasing data volumes

 IT not the hero – dissatisfied business users

 Processing and analysis results delayed

 Data not in real time


[ Why the Need for SAP HANA?

Challenges for Business:
 Inadequate access to real-time operational information

 Need to react faster to events impacting business

 Need to quickly uncover trends and patterns by functional
users – empower users/organizations

 Need to improve business processes


[ Why Use SAP HANA?

 HANA enables businesses to make smarter, faster
decisions through real-time analysis and reporting,
combined with dramatically accelerated business
processes

 Lack of delay between insight and action turns business
into a “real time business”

[ HANA Architecture


[ The “Heart” of SAP HANA


[ In-Memory Computing Engine (Simplified)


[ What is In-Memory?

 In-memory means all the data is stored in the memory
(RAM)

 There is no time wasted in loading the data from hard disk
to RAM, or while processing, keeping some data in RAM
and some data on disk temporarily

 Everything is in-memory all the time, which gives the
CPUs quick access to data for processing


[ SAP HANA Column Storage Vs. Row-Based
Storage
 Storing data in columns is not a new
technology, but it has not been
leveraged to its full potential, yet

 The columnar storage is read-
optimized, that is, the read operations
can be processed very fast. However,
it’s not write-optimized, as new insert
might lead to moving a lot of data to
create a place for new data

 HANA handles this well with delta
merge. The columnar storage
performs very well while reading and
the write operations are taken care of
by the In-Memory Computing Engine
(IMCE) in some other ways


[ Column Storage Opportunities
 Compression: As the data written next
to each other is of same type, there is no
need to write the same values again and
again

 Partitioning: HANA supports two types
of partitioning. A single column can be
partitioned to many HANA servers, and
different columns of a table can be
partitioned in different HANA servers.
Columnar storage easily enables this
partitioning

 Data stripping: When querying a table,
there are often times where a lot of
columns are not used

 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

[ Multiple Engines

 HANA has multiple engines inside its computing engine
for better performance
 HANA supports both SQL & OLAP reporting tools; there
are separate engines to perform operations respectively
 There is a separate calculation engine to do calculations.
There is also a planning engine used for functional
reporting. Above all sits something like a controller which
breaks incoming requests into multiple pieces and sends
sub queries to these engines. There are separate row and
column engines to process operations between tables
stored in rows and tables stored in column format


[ What is Ad Hoc Analysis?
 In traditional data warehouses, such as SAP BW, a lot of
pre-aggregation is done for quick results

 The IT administrator decides which information might be
needed for analysis and prepares the result for the end
users

 Results in fast performance but the end user has no
flexibility

 With SAP HANA and its speedy engine, no pre-
aggregation is required. The user can perform any kind of
operation in reports and does not have to wait hours to
get the data ready for analysis in real time.
