SAP - HANA

 

 

What is SAP-HANA?

 

-- SAP HANA is a combination of hardware and software specifically made to process massive real time data using In-Memory computing.

 

-- Explore and analyze vast quantities of data from virtually any data source at the speed of thought. With powerful in-memory computing, you can work with information captured in real time, so that you are constantly on top of changing business realities as events unfold.

 

--In-memory technology gives you the power to instantly access and analyze transactional and analytical data. Dramatically improve your planning, forecasting, optimization, and processes while reducing TCO with less hardware, maintenance, and testing.

 

SAP HANA Architecture:

 

SAP HANA database consists of multiple servers and the most important component is the Index Server. SAP HANA database consists of Index Server, Name Server, Statistics Server, Preprocessor Server and XS Engine.

 

1. Index Server:  contains the actual data and the engines for processing the data. It also coordinates and uses all the other servers.
1. Name Server:  holds information about the SAP HANA databse topology. This is used in a distributed system with instances of HANA database on different hosts. The name server knows where the components are running and which data is located on which server.
3. Statistics Server:  collects information about Status, Performance and Resource Consumption from all the other server components. From the SAP HANA Studio we can access the Statistics Server to get status of various alert monitors.
5. Preprocessor Server:  is used for Analysing Text Data and extracting the information on which the text search capabilities are based .
7. XS Engine:  is an optional component. Using XS Engine clients can connect to SAP HANA database to fetch data via HTTP.
