Introduction To SAP HANA Database- For Beginners
SAP HANA Database:
SAP HANA is an in-memory database:
- It is a combination of hardware and software made to process massive
real time data using In-Memory computing.
- It combines row-based, column-based database technology.
- Data now resides in main-memory (RAM) and no longer on a hard disk.
- It’s best suited for performing real-time analytics, and developing
and deploying real-time applications.
An in-memory database 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. Everything
is in-memory all the time, which gives the CPUs quick access to data for
processing.
The speed advantages offered by this RAM storage system are further accelerated
by the use of multi-core CPUs, and multiple CPUs per board, and multiple boards
per server appliance.
Complex calculations on data are not carried out in the application layer, but
are moved to the database.
SAP HANA is equipped with multiengine query processing environment which
supports relational as well as graphical and text data within same system. It
provides features that support significant processing speed, handle huge data
sizes and text mining capabilities.

So is 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 HANA database, easy to use
data modeling tool called HANA studio and other software to load data in the
database.

SAP HANA Architecture
With the help of technology like SLT replication, data can be moved to HANA in
real time. It is also possible to copy data from SAP BW or other database into
SAP HANA. In HANA, we can use modeling tool called HANA Studio to build the
logic and structures and use tools e.g. SAP BusinessObjects, SAP Visual
Intelligence to visualize or analyze data.

An insight into SAP HANA Architecture
Can I just increase the memory of my traditional
Oracle database to 2TB and get similar performance?
NO. You might have performance gains due to more memory available for your
current Oracle/Microsoft/Teradata database but HANA is not just a database with
bigger RAM. It is a combination of a lot of hardware and software technologies.
The way data is stored and processed by the In-Memory Computing Engine
(IMCE) is the true differentiator. Having that data available in RAM
is just the icing on the cake.
