SAP in classroom teaching…

Students as student workers at SAP

Thesiswork (Bachelor/Master)

At SAP or SAP customers

Many graduates at SAP and SAP customers

Former SAP employees as faculty

… and beyond

In general universities should be independent of software

companies

However the demand on graduates with knowledge in

architecture and application in leading software technology

cannot be ignored as part of an education which meets

practical standards

Ivory tower or product specialist?

The demand for BI students has surpassed the supply

The foundational skills are still the most critical for new BI technology

Employers were not satisfied with the graduates‘ practical skills

Students should have experiences with real data, real tools, reporting, and dashboard

SAP BW on HANA: Architecture

SAP BW

SAP Business Warehouse

– Is a DW application on top of a RDMS

– In the market since 1997

– Originally a “DWH for SAP R/3“ now a featurecomplete EDW platform

– Today > 15000 customers (4000+ on HANA)

3 Editions

– SAP BW on AnyDB More or less legacy

– SAP BW on HANA

– BW4/HANA The choice for new installations

BW on HANA vs. BW4/HANA

BW on HANA

• New objects have been developed in BW on HANA to leverage the HANA platform

• New objects replace old objects like InfoCubes developed for BW on AnyDB

• New objects are recommended, but old objects still functionable (compatibility)

– Upgrade path for existing installations to BW on HANA

– Customers can then subsequently optimize their models and architecture for HANA in own

speed

BW4/HANA

• Can be (simplified) seen as BW on HANA but without old objects

• Clean new system, streamlined for HANA only

• Perfect for new installations

• Will be the future

• Our curriculum: Is BW4/HANA ready, as we only use new objects!

Problem– Several BI clients of the manufacturer with frequent changes, unclear product strategy,

partly high administrative overhead (additional servers, user management)

Solution– Focus on use cases OLAP Analysis and Dashboards

– Use tool that connect to SAP BW directly (without additional layer)

– Query as universal point of eaccess to BW data

SAP BO Analysis for Office– Excel Addin

– Ad Hoc Analysis, OLAP

SAP BO Design Studio– Design of Dashboards

– Web (HTML5)

– Mobile

Possible Extension: SAP Lumira– Self Service BI

– Visualisation

Information Access Layer
