Agenda



BW on HANA – Smarter, simpler, more efficient How Does BW running on xDB differ from BW running on HANA ?

The database is completely re-architected from scratch to benefit from cheaper memory and parallelism

ABAP Code in BW is reduced by pushing down processing logic to HANA

�  Excellent query performance for improved decision making

�  Performance boost for Data Load processes for decreased data latency

�  Accelerated In-Memory planning capabilities for faster planning scenarios

�  Flexible combine EDW with HANA-native data for real-time insights and decision making

�  Data persistency layers are cut off and reduced administration efforts

�  Simplified data modeling and remodeling

The Reporting UI is not affected. BW Modeling environment will be simplified and unified

SAP’s strategic EDW solution SAP BW 7.4 on HANA – evolving BW 7.3 on HANA to “HANA BW”

Only the combination of BW and HANA enables us to

… simplify the data modeling processes

… increase the agility of the Enterprise Data Warehouse

… reduce the complexity of the EDW landscape

… combine the strengths of an SQL oriented approach with an Integrated EDW application

Seamless consump-on

of data

Reuse BW services to manage and

analyze the data

One common modeling

environment

Process large amounts of data

faster

Agenda



HANA Analysis Process Planned with BW 7.4, SP5/SP6 on HANA

Enhanced analysis capabilities �  Execute HANA-native functions directly

on BW InfoProvider data e.g.: –  Clustering, association algorithms,

regression analysis, anomaly detection, weighted score, exponential smoothing, etc.

�  Execute complex and data intensive processes on HANA without losing the integrity and integration with the BW environment

�  Materialize the result of a HANA Analysis Process in HANA for further processing – automated

�  Supporting also a scheduled batch processing use case

Sources �  Most BW InfoProvider �  Database tables

Supported procedures/algorithms �  AFL-functions (PAL, …) �  L-script, R-script, SQL-script procedure.

Supported output �  Analytic Index (modeled/generated/virtual), �  DSO, database table �  HAP Input (“stacked HAPs”)

Staging integration �  stand-alone, �  triggered via APIs from applications, �  process chain variant, �  source of a DTP

Agenda



Flexible consumption of external data models Planned with BW 7.4, SP5/SP6 on HANA

Flexible and easy consumption of external data models building a BW Open ODS Layer Agile modeling

�  Integrate external data models for –  direct query access –  staging scenarios –  switch between both options

�  Field based modeling complementing InfoObject modeling

�  Integrate with existing BW models �  Gradually build up models and architectures based on

relational schemas �  Possibility to start modeling from facts developing

towards the dimensions �  Enables fast prototyping – quick ROI

Immediate light weight querying �  Integrated with BW authorization concept

Smart Data Access Planned with BW 7.4, SP5/SP6 on HANA

Enhanced Business Flexibility by providing “the logical EDW” Data Federation in diverse EDW landscapes

•  Smart data access – read access to relational and non-relational sources via ODBC

•  Enables access to remote data access just like “local” table

•  Supports data location agnostic development •  No special syntax to access heterogeneous data

sources •  Non-disruptive evolution •  BW based Analytic Services on external data

Scenario •  Make other DWHs transparent to HANA •  Evolve from virtual table to persistent structure by

establishing ETL without major effort •  Consolidating / rationalizing the DWH landscape •  Consumption of HANA datamart scenarios from

second HANA database
