3 In Memory Processing General Highlights BWA BWA = SAP BW Accelerator

4 SAP HANA In Memory Options SAP HANA is sold as an in-memory appliance. This means that both Software and Hardware are included from the vendors Currently you can buy SAP HANA solutions from Cisco, Dell, Fujitsu, IBM, and Hewlett-Packard SAP HANA currently indexes the data from a variety of sources, including ERP and BW and store the result on a dedicated server The future of SAP HANA is to replace the databases of ERP and BW and run these on the in-memory platform Source SAP AG,2011 SAP HANA has the potential to radically change the way databases operate and make systems dramatically faster.

5 The Different Editions of HANA

6 Looking Inside SAP HANA In-Memory Computing Engine (IMCE) Disk Storage Data Volumes BusinessObjects Data Services Log Volumes AAAA Metadata Manager Authorization Manager Transaction Manager Relational Engine -Row Store -Column Store Load Controller SQL Script Calculation Engine Replication Server SQL ParserMDX Session Manager Inside the Computing Engine of SAP HANA we have many different components that manage the access and storage of the data. This include MDX and SQL access, as well as Load Controller (LC) and the Replication Server.

7 Row based index

8 Row- vs. Column-Based Indexing (cont.) As we can see, there are only 7 unique states and 3 unique customer classes in the data. This allows SAP HANA to compress this data set significantly By including the Row ID in the column-based index in SAP HANA, the ownership of the values in the index can still be mapped back to the record Column-based indexes on fields with repeated values often leads to better compression ratios and thereby lower size of the indexes (as we can see, there are few values repeated in the rows).

9 SAP HANA Virtual Marts and Applications Virtual data marts and new applications were built that run on SAP NetWeaver BW, which is again enabled by SAP HANA in-memory processing ERP Database HANA (in-the works) Virtual Data Marts Applications Databases Virtual Data Marts Virtual Data Marts Virtual Data Marts Files This provides much tighter integration with the source system (less data latency) and much faster query response time for high-volume analysis Applications developed by SAP 1.Planning & consolidation 2.Customer revenue performance mgmt 3.Predictive segmentation & targeting 4.Trade promotion management 5.Merchandise & assortment planning 6.Sales & operations planning (SOP) 7.Demand signal repository 8.Profitability analysis 9.Dynamic cash management 10.Strategic workforce planning 11.Smart meter analytics (power companies)

12 SAP HANA Loading the Application and Performance You can load the application based on the logs in the source system, ETL- based (Extract Transform and Load) loads, and SAP trigger-based replication Tool Purpose BusinessObjects Data Services 4.0 – ETL-based replication Sybase replication server & Load Controller – Log-based replication SAP Landscape Transformation (LT)– Trigger-based replication Log based replication is possible on IBM DB 2 LUW/UDB, MSFT SQL Server Enterprise Edition, Oracle Enterprise Edition, and Sybase ASE

70 Our Customer table in HANA

71 What can you do with HANA and BO Explorer? The system looks at the data and formats it based on implied hierarchies (i.e., time, geography, customer) as well as measures. Users may navigate and change measures, graphs, and tables.

72 New Calculations Any data panel can be sorted in many ways Measures used on any graph can be calculated on-the-fly. We can also add our own measures In our example we are adding the measure Margin Per Unit as total margin divided by quantity sold 72

73 HANA Optimized InfoCubes

74 74 Data Store Objects (DSO) In HANA Main IndexDelta Index History Index Insert Only Index Read delta, between snapshot 1 and 2 Index Read Data Load Activation The DSO in HANA is a closed object where you can do: Index reads (snapshots) Delta reads for updates Activate data Querying PS! a table, an analytic or calculation view in a HANA schema can be accessed via a BW DataSource. This is based on DB connect using a second DB connection to the underlying HANA DBMS. Source: T. Zurek, SAP AG

75 SAP HANA Test Drive You can see demos and do a test drive at: https://www.experiencesaphana.com This site contains a lot of great information and you can also try the Information Composer and see recorded demos.

76 Register and Take a Free BI Test Drive with SAP HANA You can register for a free test drive at: https://bi.ondemand.com/session/new You can also upload your own data and try the tool to see if it is something for your organization. There is even quick guides, videos, and wizards to get you started. 76
