3 What is SAP HANA? SAP HANA is an in-memory data platform that is deployable as an onpremise appliance, or in the cloud. It is a revolutionary platform that s best suited for performing real-time analytics, and developing and deploying real-time applications. At the core of this real-time data platform is the SAP HANA database which is fundamentally different than any other database engine in the market today SAP AG. All rights reserved. Public 3

4 What is SAP HANA? In-memory database hardware - 8 CPU*10 cores, 1TB RAM software - column store, compression, partitioning 3B scans/s/core, 12.5 aggregations/s/core Analytics real-time analyze as data keeps rolling in agility logical views Applications integrated, lightweight application server 2013 SAP AG.

5 What is SAP HANA? Side-by-Side Scenarios (2010) Agile Data Marts Real-time Operational Reporting SAP BW on HANA (2011) SAP HANA as primary persistence SAP NW Application Server on HANA SAP HANA as data platform (2012) SAP HANA for SAP Business Suite SAP HANA for custom applications 2013 SAP AG.

6 How do I use SAP HANA?

7 Storing data in SAP HANA SAP HANA speaks SQL. > CREATE SCHEMA ka; > CREATE TABLE ka.complaints (cmplid INT, ); > INSERT INTO ka.complaints VALUES (1, ); > SELECT cmplid, FROM ka.complaints; 2013 SAP AG. All rights reserved. Public 7

8 Storing data in SAP HANA Applications writing directly into SAP HANA Real-time replication using SAP LT Replication Service Data loaded from files using IMPORT / INSERT Message queue integration with Sybase ESP ][ ][ ][ Data loaded at certain events using Business Objects Data Services 2013 SAP AG.

18 SAP HANA Programming Model Paradigm Shift - Responsibilities in Runtime Layers Classic Application Server Layers HANA Native Applications Client Display pre-rendered UI Proprietary Protocol Application Server UI Rendering Application Logic DBI/DBSL, DB buffer Browser Complete UI Rendering HANA http(s), OData (pure data only) Extended Application Services Procedural Application Logic HdbNet (minimal data volume) Database SQL SQL Database Data-intense Application Logic 2013 SAP AG.

19 SAP HANA Programming Model Technologies Presentation HTML5 / SAPUI5 Client-side JavaScript Browser Complete UI Rendering http(s), OData (pure data only) Control Flow OData Server-side JavaScript Data Processing SQL / Views / SQLScript Application Function Library (AFL) HANA Extended Application Services Procedural Application Logic Database HdbNet (minimal data volume) Data-intense Application Logic 2013 SAP AG. All rights reserved. Public 19

20 SAP HANA Native Applications SQLScript What is SQLScript? Interface for applications to access SAP HANA; extension of ANSI Standard SQL Language for creating stored procedures Declarative logic including SELECT queries, built-in Calculation Engine Functions Orchestration logic including Data Definition Language (DDL), Data Manipulation Language (DML), assignment, imperative logic SQLScript allows execution of data intensive calculations inside SAP HANA Eliminates need to transfer large amounts of data from the database to the application Maximum benefit from SAP HANA features such as fast column operations, query optimization and parallel execution Advantages (compared to SQL) Functions can return multiple results Complex functions can be broken down - modular programming, reuse, and understandability Functions can have parameters Supports local variables for intermediate results with implicitly defined types Provides control logic such as if/else 2013 SAP AG. All rights reserved. Public 20

21 SQLScript Code example using SQL CREATE PROCEDURE getcomplaintsaggsql ( in cmplid INTEGER, out o_complaints tt_complaints) LANGUAGE SQLSCRIPT SQL SECURITY INVOKER READS SQL DATA AS BEGIN /***************************** Write your procedure logic *****************************/ ta_complaints = SELECT CMPLID, MAKE, MODEL, CDESCR, COUNTER FROM "KA"."COMPLAINTS"; ag_complaints = SELECT MAKE, SUM(COUNTER) AS TOTAL_FOR_MAKE FROM "KA"."COMPLAINTS" GROUP BY MAKE; jo_complaints = SELECT T1.CMPLID, T1.MAKE, T1.MODEL, T1.CDESCR, T1.COUNTER, T2.TOTAL_FOR_MAKE FROM :ta_complaints AS T1, :ag_complaints AS T2 WHERE T1.MAKE = T2.MAKE; o_complaints = SELECT CMPLID, MAKE, MODEL, COUNTER, TOTAL_FOR_MAKE FROM :jo_complaints WHERE CMPLID = :cmplid; END; Q1 Complaints Q3 Q4 Result Q SAP AG.

22 Using data in SAP HANA Set Operations Operation Calculations on Data Business Function Calls R Procedure Calls Predictive Analysis Algorithms Operations can be all sorts of operations on data not just basic SQL operations but also more complex logic 2013 SAP AG. All rights reserved. Public 22

23 SAP HANA Application Function Library What is Application Function Library (AFL)? Set of native, pre-built, parameter-driven, commonly used algorithms Optimized for performance Functions can be called from SQLScript The Business Function Library (BFL) contains algorithms primarily related to finance Stock Flow, Lease, Depreciation, Discounted cash flow, Inflated cash flow, The Predictive Analysis Library (PAL) contains algorithms primarily related to predictive analysis and data mining Regressions, KNN, k-means, Exponential Smoothing, Apriori, 2013 SAP AG.

25 SAP HANA Extended Application Services What are Extended Application Services? Small footprint application server / web server for application development inside SAP HANA Enable application development and deployment while minimizing architectural layers Create apps that have an http-based UI (browser, mobile apps) Apps run directly on SAP HANA, w/o additional external servers or components simplified system architecture; low TCO Tight integration with SAP HANA DB best possible performance Scope Lightweight web-based applications Complex Enterprise Business Applications 2013 SAP AG.
