In-Memory usage scenario:Accelerating existing processes

SAP HANA

In-Memory Appliance is used as second databaseaccelerate existing applications

In-Memory Appliance serves as secondary database for SAP prodERP or CRM

Data is replicated / written into In-Memory in real time for secon

User interface remains unchanged to ensure non disruptive accel

Application is accelerated by reading the mass data from the In-Mdatabase

Modeling for HANA 1.0Using In-Memory Computing Studio

Step1: (Attribute View)

Seperate Master Data Modeling fromFact data

Build the needed master data objects as Attribute Views Join text tables to master data tablesIf required: join master data tables to each other (e.g. join Plant to Material)

Step 2: (Analytical View)

Create Cube-like view by joining attributes view to Fact data Build a Data Foundation based on transactional table

Selection of Measures (key figures) ... Add attributes (docking points for joining attribute views)

Join attribute views to data foundationLooks a bit like a star schema


15/22



Step 3: Calculation View for more complex modelsComposite view of other views (tables, re-use join, olap views)Consists of a Graphical & Script based editor SQL Script is a HANA-specific functional script language

Think of a SELECT FROM HANA as a data flow JOIN or UNION two or more data flowsInvoke other (built in CE or generic SQL) functions


16/22



Step 4: Analytic Privileges Analysis authorizations for row-level security

Can be based on attributes in analytic views

Analytic privilege is always a concrete implementationi.e., Specific authorization for specified values of given attribute

you have to create privileges for each group of users

HANA Modeler SDK - Overview

Enables application developers to create their analytical models programmatically

Developed using JAVA and can be consumed only by JAVA based applications. A programminglanguage agnostic SDK is currently out of scope

Has no eclipse platform dependency; so it can be used by plugin development as well as plain JAVAbased applications

Currently it uses org.eclipse.osgi in order to handle language dependent messages

SDK is EMF dependent; This requires SDK to be bundled with EMF plug-in JARsSDK uses EMF in standalone way

Creating models using HANA SDKGet Object type specific EMF model and fill itCreate the object from XML conforming to our XSD
