Hi Greetings of the day.
SAP HANA
SAP HANA-High Performance Analytic Appliance is an
in-memory, column-oriented relational database system. Both hardware and
software architecture has been changed for SAP-HANA. Hardware is changed to store the
data and software is changed for real-time processing. The exponential data
growth, new exotic data types lead to invention of HANA system to provide the
data in real time. It has ability process more than 2T of data within seconds.
The basic key features of SAP-HANA are :-
IMDB( In memory
database):- whole of the data in HANA resides in in-memory not on harddisks as
it used to be in classical databases. As all the data resides is present
in-memory whenever the data is required it is fetched in real time removing the
concept of first sending call to fetch data from hard didk and then forward the
same to execute.
Column oriented:-
Data was always stored in the form of row based architecture on hard disk but
in HANA data is stored in the form of columns which helps to save the time. If
we take customer table for instance, and want to access the name of customer
who has received products more than 1000kg(data stored in filed XYZ). In
row-based architecture, all the data related to customer will be examined
instead of examine XYZ field only but in column based architecture only XYZ
will be examine and based on it’s output customer names will be displayed.
MPP(Massive
Parallel Processing):- It is an divide
and conquer strategy. In initial systems at one time processor of a computer
executes only one task at a time regardless of being i5,i3 and so on. But in
HANA strategy is used which has ability to perform tasks simultaneously i.e. if
system is i5 then all the divided portions can work parallel on same time.
Being an SAP HANA learner it is advisable to let you know
that being an HANA consultant you have to do the following jobs:
Data Modeling
Data Provisioning
Data Reporting.
