How can my ABAP code benefit from SAP HANA? Recommendations

Possibility to use HANA-specific features

Code running on all supported database systems

Prefer Advanced ABAP database programming features to optimize ABAP code advanced Open SQL advanced ABAP view building

use ABAP-managed procedures where needed, but think of fallbacks in case the code also has to

support traditional database systems

Use SAP HANA content integration if requirements cannot be fulfilled by Advanced

ABAP database programming

to consume pre-packaged content (e.g. SAP HANA Live)

to develop reusable artifacts across application stacks

The SAP schema is managed by the AS ABAP only create artifacts in SAP schema through

ABAP use APIs to write to tables in SAP schema and avoid using native SQL / SQLScript to write to

tables SAP schema

What are completely new

possibilities?


Example 1: Application Function Libraries Overview

Application Function Libraries

libraries of reusable functions linked dynamically to the SAP HANA database kernel (implemented in C++)

can be used to perform data intensive and complex calculations

BFL and AFL generally released as of SAP HANA SPS5

Business Function Library (BFL)

contains pre-built, parameter-driven business functions (examples: annual depreciation, days outstanding)

Predictive Analysis Library (PAL)

contains statistical algorithms from areas like clustering, classification, social network analysis

SAP HANA

Index Server

Business Function

Library (BFL)

Predictive Analysis

Library (PAL)


Example 1: Application Function Libraries Exemplary functions

function: Linear Average (BFL)

calculates a linear average, in which larger weights are applied to more recent

periods

weights decrease lineary as you look back over time

function: ABC Analysis (PAL)

classify objects (customers, employees, products) based on a particular measure group objects by their estimated importance (A, B, C objects)

function: K-means (PAL)

partition records into k clusters in which each record belongs to the cluster with the

nearest center

e.g. used to group customers into segments


Example: ABC analysis of products

Classification based on revenues attributed to the products

A products: 20% of the products accounts for 70% of the revenue

B products: 30% of the products accounts for 20% of the revenue

C products: 50% of the products accounts for 10% of the revenue

Example 1: Application Function Libraries Demo scenario

Product ID Product Name Revenues Currency Classification

HT-1000 Notebook Basic 15 1.500.000 EUR A

HT-1001 Notebook Basic 16 800.000 EUR B

HT-2000 7 Widescreen DVD player

1.700.000 EUR A

HT-2001 10 portable DVD player 500.000 EUR C

Example 2: Business rules SAP NetWeaver Decision Service Management (DSM)

Example 2: Business rules DSM and SAP HANA (1/2)

Dynamic Database View: deployment to SAP

HANA generates a result view based on database

(tables, views) and decision table content

database table or view as data source

decision table for calculated columns

result view to combine data source with calculated columns

Decision table processed on SAP HANA database by SELECT on result view

can be used directly in ABAP and in database lookup expressions

Database table or view

Column 2

A 10 100 1.000

B 20 300 3.000


Example 2: Business rules DSM and SAP HANA (2/2)

Usage of database procedures in DSM

functions on SAP HANA

either based on database procedure proxies

or based on ABAP-managed procedures

allows to push down expensive expressions to the database

Analyze DSM expressions with SAP HANA

Example: decision table

Which row is mostly evaluated as true?

How do values develop over time?

Row 1 (100, 1.000)

Row 2 (200, 2.000)

Row 3 (300, 3.000)

Database

Analysis

Tex

Text Search

search character-type columns of database tables in column store

search operations: exact, fuzzy, linguistic

functions: ranking, snippets, facets

requires creation of so-called fulltext index

Text Analysis

structure, transform, enrich unstructured data for the purpose of discovery or analysis

happens based on fulltext index (optional configuration for a fulltext index)

results of text analysis are stored in a database table


Example 3: Text Search / Analysis Using text search capabilities in ABAP

Fulltext index in the SAP HANA database

is implicitly created only for column store data types TEXT and SHORTTEXT

has to be explicitly created for other character-type columns

Creation of fulltext index through ABAP

create (extension) index in transaction SE11

choose exactly one field for the index and specify that the index is a fulltext index

available as of ABAP 7.4 SP2

Access by means of native SQL

SELECT pd.product_id, tx.text

FROM snwd_pd AS pd

INNER JOIN snwd_text_key AS tk

ON tk.node_key = pd.name_guid

INNER JOIN snwd_texts AS tx

ON tx.parent_key = tk.node_key

WHERE CONTAINS(tx.text, 'notbook',
