What is SAP HANA ? :

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.com

What is real-time analytics?:

What 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.com

 Is HANA really fast?:

 Is 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 what’s 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.com

Compression::

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. 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. Let’s 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::

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. www.arkansys.com
