What is SAP HANA?

How do I use SAP HANA?

How can I develop applications on SAP HANA?

That’s it?


What is SAP HANA?

SAP HANA is an in-memory data platform that is deployable as an on-

premise 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.


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


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

How do I use SAP HANA?


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;


Storing data in SAP HANA

Applications writingdirectly into SAP HANA

Data loaded from filesusing IMPORT / INSERT

Data loaded at certain eventsusing Business Objects Data Services

Real-time replication using SAP LT Replication Service

][ ][ ][Message queue integrationwith Sybase ESP


Using data in SAP HANA

You define views, to make dataeasily accessible to everyone.

Data ProcessingSQL / Views / SQLScriptApplication Function Library (AFL)


SAP HANA Native ApplicationsSQLScriptWhat is SQLScript?

Interface for applications to access SAP HANA; extension of ANSI Standard SQLLanguage for creating stored proceduresDeclarative logic including SELECT queries, built-in Calculation Engine FunctionsOrchestration logic including Data Definition Language (DDL), Data Manipulation Language (DML), assignment, imperative logic

SQLScript allows execution of data intensive calculations inside SAP HANAEliminates need to transfer large amounts of data from the database to the applicationMaximum benefit from SAP HANA features such as fast column operations, query optimization and parallel execution

Advantages (compared to SQL)Functions can return multiple resultsComplex functions can be broken down - modular programming, reuse, and understandabilityFunctions can have parametersSupports local variables for intermediate results with implicitly defined typesProvides control logic such as if/else


SQLScriptCode example using SQL

CREATE PROCEDURE getComplaintsAggSQL (in cmplid INTEGER, out o_complaints tt_complaints)

LANGUAGE SQLSCRIPTSQL SECURITY INVOKERREADS SQL DATA ASBEGIN/***************************** 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 T2WHERE T1.MAKE = T2.MAKE;

o_complaints = SELECT CMPLID, MAKE, MODEL , COUNTER, TOTAL_FOR_MAKE

FROM :jo_complaints WHERE CMPLID = :cmplid;END;

What is Application Function Library (AFL)?

Set of native, pre-built, parameter-driven, commonly used algorithmsOptimized for performanceFunctions can be called from SQLScriptThe Business Function Library (BFL) contains algorithms primarily related to financeStock Flow, Lease, Depreciation, Discounted cash flow, Inflated cash flow, …

The Predictive Analysis Library (PAL) contains algorithms primarily related to predictive analysis and data miningRegressions, KNN, k-Means, Exponential Smoothing, Apriori, …

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 DBbest possible performance

ScopeLightweight web-based applicationsComplex Enterprise Business Applications

SAP HANA Fulltext Search and Text Analysis

CapabilitiesNative full text searchIn-database text analysisGraphical modeling of search modelsInfo Access (InA) toolkit for HTML5 UIs

BenefitsExploit unstructured content in SAP HANA without additional costsExtract meaningful information from textCombine structured and unstructured information for unified information accessLess data duplication and movement – leverage one infrastructure for analytical and search workloadsSpeed up HTML5 application development – InA toolkit


SAP HANASearch Model Example


SAP HANA Info Access (InA) toolkit for HTML5


SAP HANAText Analysis

CREATE FULLTEXT INDEX FTI_COMPLAINTSON COMPLAINTS(CDESCR)CONFIGURATION 'EXTRACTION_CORE' TEXT ANALYSIS ON;

Source Table “COMPLAINTS”


SAP HANAText Analysis – Downstream Processing

Text Analysis results are stored in a table and therefore can be leveraged in all supported HANA scenarios

“Standard” analytics Create Analytic Views and Calculation Views on tope.g. companies mentioned in news articles over time

Data mining, predictiveUse R, Predictive Analysis Library (PAL) functionse.g. clustering, time series analysis etc.

Search Based ApplicationsCreate a search model and build a search UI with the HANA Info Access (InA) toolkit for HTML5Text Analysis results can be used to navigate and filter search resultse.g. people finder, search UI for internal documents


Use Cases

Real-time analytics on large data volumes

Financials

Production planning, monitoring

Sales optimization

Combine structured and unstructured information

Patent research

Consumer sentiment analysis, brand monitoring

Healthcare
