sap hana certification questions and answers

Overview and Architecture of HANAWhat is HANA ndashHigh Performance Analytical Appliance - In memory computingengine

In memory computing studio as a frontend for modeling and administration

HANA is connected to ERP systems Frontend modeling studio can be used for loadcontrol and replication server management

Two types of Relational Data stores in HANA Row Store Column Store

SAP BOBJ tools can directly report on HANA

Data from HANA can also be used in MS Excel - MDX

Row Store ndash Traditional Relational Database The difference is that all the rows are inmemory in HANA where as they are stored in a hard drive in traditional databases

Column Store ndash The data is stored in columns like in SAP BWA

Persistence Layer In memory is great but it is volatile and data can be lost withpower outage or hardware failures To avoid this HANA has a Persistence Layercomponent which makes sure that all the data in memory is also store in a hard drive

which is not volatile

Session Management This component takes care of logon services

Two processing engines ndash Well data is in memory which is good but How do Iextractreport on the data HANA has two processing engines one is based on SQLwhich accepts SQL queries and the other one is based on MDX

HANA Supports Sybase Replication Server ndash Sybase Replication Server can be usedfor real time synchronization of data between ERP and HANA

Modeling StudioUsing Modeling Studio you can

Specify which tables are stored in HANA first part is to get the meta data and then scheduledata replication jobs

Manage Data Services to load the data from SAP BW and other 3rd party systems

Manage connections to ERP instances current release does not support connecting toseveral ERP instances

Use Data services to for the modeling

Do modeling in HANA itself (This is independent of Data services)

You can also do modeling can also be done in Business Objects Universes which isnothing but joining fact and dimensional tables

ReportingClient tools can access HANA directly Like MS EXCEL SAP BI 40 Reporting toolsDashboard Design Tool (Xcelsius) can also access HANA directly

Third party reporting tools can leverage ODBC JDBC and ODBO (for MDX requests) driversin HANA for reporting

HANA supports BICS interface

Request Processing and Execution Control SQL Script MDX statements are passed to calculation models

Optimizer which is included in calculation engine optimizes for better performance

Calculation Engine

Modeler can define data sources as inputs and different operations (joinaggregation projection) on top of them for data manipulation

The calculation engine will break up a model into sub processes for optimizedperformance on cost based

System will use maximum resources to achieve max through put

Planning Engine Will be included in next release Will include planning functions likedistribute and copy functions

ROW StoreOne of the relational engines to store data in row format

Pure in-memory store (Future versions will also have an option of disk basedstore)

In memory object store (in future) for live cache functionality

Transactions Version Memory is the heart of row store

Row store architecture

Write operation mainly go into Transactional Version Memory

INSERT also writes to persisted segment

Moves visible version from memory to persisted segment

Clears outdated record versions from Transactional Version memory

Row Store tables have a primary index

Row ID maps to primary key

OVERVIEW

SAP BWREALTIMEINTERVIEWQSTampANSWEAR

SAP BWINTERVIEWQST

SAP BWINTERVIEWQST


Secondary indexes can be created

Row ID contains the segment and the page for the record

Indexes in row store only exist in memory

Index definition stored with table meta

Column StoreImproves read functionality significantly also improves write functionality

Highly compressed data

No real files virtual files

Optimizer and Executer ndash Handles queries and execution plan

Delta data for fast write

Asynchronous delta merge

Consistent view Manager

Main store compressed and read optimized ndash Data is read from Main Store

Delta Store ndash Write optimized ndash for write operations

Asynchronous merge move the data from delta store to main store

Compression by create dictionary and applying further compression methods

Even during the merge operation the columnar table will still be available for read and writeoperations To fulfill this a second delta and main storage are used internally

Merge operation can also be triggered manually with an SQL command

Persistence LayerPersistence Layer is needed as Main memory is volatile


Provides Backup and Restore functionality

One Persistency Layer takes care of both row and column stores

Regular Save Points

Logs capturing DB transactions since last save point

Actions during system restart

Last save point must be restored plus undo logs must be read anduncommitted transactions saved with last save point and apply redo logs

Complete content of row store is loaded into memory during start process

Flags can be set for column store to specify which tables are loaded duringsystem restart

ModelingModeling only possible for Column tables

Information Modeler only works for column tables

Replication servers create tables in column store per default

Data Services creates tables in column store per default

SQL to create column table Create COLUMN TABLE

Store can changed with ALTER TABLE

System tables are create where they fit best

Schema SYS -gt administrative table of engine

Tables from statistics server


In-Memory Computing StudioBuild with java based eclipse

Navigator to access different HANA systems on left Quick Launch View at the middle andProperties view at the bottom

Information Modeler Features

Database views

Choice to publish and consume at 4 levels of modeling

Attribute view analytic view

Physical tables and Information Models

Importexport models data source schemas mass and selective load

Landscapes

The models are just virtual definitions they dont store actual data

Attribute View

Attributes add context to data

Attributes are modeled using attributes views

Can be regarded as Master Data Tables

Can be linked to fact tables in Analytical Views

A measure eg weight can be defined as an attributes

Table Joins and properties

Left outer right outer full outer or text table

Cardinality 11 N1 1N

Language Column

Analytic View

Similar to Cube

Analytic Views does not store any data The data is stored in column store tableor view based on Analytical View structure


Attributes and Measures ndash Like key figures

Data Preview ndash Similar to list cube functionality

Calculation View

Define table output Structure

Write SQL statement

Ensure the selected fields corresponds to previously defined outputstructures

SQL Scripts unlike SQL procedure cant change any data they are read only

Other Notes

External tools can connect to HANA using JDBC and ODBC drivers

HANA currently doesnt support complete MDX set it supports EXCEL 2010 standard MDX

BWA Hardware can be upgraded to HANA given that hardware is relatively new

BWA Licenses can be transferred to HANA

ERP and BW can be connected to HANA using Data services or Sybase Replication

No name space concept in HANA at this moment so two ERP instances cant be connectedto HANA However this issue can be avoided using data sources

CRM also can use HANA

Data from BW into HANA can be loaded into using Data Services and Info spokes

which is not volatile

Session Management This component takes care of logon services

Two processing engines ndash Well data is in memory which is good but How do Iextractreport on the data HANA has two processing engines one is based on SQLwhich accepts SQL queries and the other one is based on MDX

HANA Supports Sybase Replication Server ndash Sybase Replication Server can be usedfor real time synchronization of data between ERP and HANA

Modeling StudioUsing Modeling Studio you can

Specify which tables are stored in HANA first part is to get the meta data and then scheduledata replication jobs

Manage Data Services to load the data from SAP BW and other 3rd party systems

Manage connections to ERP instances current release does not support connecting toseveral ERP instances

Use Data services to for the modeling
