Motivation
Issue
Customers are facing a heterogeneous system landscape across
different locations, storing huge amount of data in different
formats
Requirement
Customers require a cost-efficient, easy-to-deploy solution to get
real-time data visibility across their fragmented data sources, e.g.
for operational reporting, monitoring, predictive analysis, search
Virtualized Access
….
Enterprise databases
Warehouse databases
Master data database
….
Report
HDFS cluster

Some typical use cases
USE CASE DESCRIPTION
Developing Apps Using Dispersed
Enterprise-Wide Data
• Build applications on HANA, but access data from other sources using HANA
smart data access, without moving data into HANA
• Initially supported sources – HANA, ASE, IQ, Teradata, HIVE/Hadoop
Federation of data in Hadoop • Access Hadoop/HIVE/Spark data from HANA
Big Data access • Access big data stores (e.g. Sybase IQ), without loading data into HANA
HANA-to-HANA • Federated HANA databases (e.g. cross-reporting)

Introducing SAP HANA smart data access
Key Value Proposition
 Enables access to remote data just like “local”
table
 Smart federated query processing
 Supports data location agnostic development
 No special syntax to access heterogeneous
data sources
 Cost savings
 Benefit from HANA functionality without
moving all data to HANA
 Rapid deployment of high-performance, data
intensive transactional and analytical
applications

SDA monitoring in the SAP HANA Cockpit
Installation
 Download content from the SAP Service Market Place (http://service.sap.com)
 Note: You can search for “SMARTDATA”

SDA monitoring in the SAP HANA Cockpit
Extract and import content as Delivery Unit Open HANA Cockpit and select the
additional SDA tiles from the catalog

SDA monitoring in the SAP HANA Cockpit
No differences to smart data access monitoring in HANA Studio, but
additionally remote user and transaction-id of the remote query are
displayed in the SDA HANA Cockpit

SAP HANA SDA Adapters - Introduction
All supported SAP HANA SDA adapters are listed in a central SAP-note 1868209.
With HANA SPS11 smart data access can use SDI adapters to access more 3rd party remote sources
and their versions.
New 3rd party remote source will only be supported by SDI adapters that can be used by SDA.

Use of SDI adapters for Smart Data Access
Conversion of a Smart Data Access remote source into a Smart Data Integration data source
Pre-requisites
• The Data Provisioning Server (DP Server) has been started
• The Data Provisioning Adapters (SDI Adapters) have been configured
Supported Conversions
SDA Adapter SDI Adapter
MSSQL (GENERIC ODBC) MssqlLogReaderAdapter
ORACLE (GENERIC ODBC) OracleLogReaderAdapter
DB2 (GENERIC ODBC) DB2LogReaderAdapter

Configure SAP SDI adapters for Smart Data Access
Installation of SDI components
• Activate DP-Server in the HANA Studio and deploy the DP-Agent on your remote source host
• Configure DP-Agent and register new SDI adapter (will be visible in HANA remote source definition screen)
Use SDI adapter
• Create remote source on new SDI adapter (you can also alter an existing remote source to the new SDI adapter)
• Browse remote object catalog and create virtual table

SDA adapter for SAP MII
The SAP HANA SDA adapter for SAP Manufacturing Integration and Intelligence (SAP MII) can be used
to connect an SAP MII back-end system to an SAP HANA system
• Delivered with SAP HANA (base) installation
• Installation and Configuration is described in SAP-note 1984859 (see attached PDF-files)
• Queries on the SAP MII side are exposed as virtual tables to SAP HANA
• The adapter transforms queries to their virtual tables into appropriate SAP MII service queries
• The results from SAP MII are then transformed into rows of the virtual tables

HANA SDA SPARK adapter
SAP HANA SDA has been providing the SPARK SQL adapters since SPS10
• SAP HANA Spark SQL Adapter is a plugin for
HANA Smart Data Access framework
• It provides access to the Spark Controller and
moderates query execution and data transfer
• SAP HANA Spark Controller enables virtual tables
on underlying Hive tables (SPS10)
• New SPS11: SAP HANA Spark Controller enables
virtual tables on HANA Vora tables
• Pre-Requisite: Download and Install HANA Spark
Controller (see also SAP note: 2177933)

SDA Performance tuning
• SAP HANA SDA optimizes the data transfer between local data and remote data primarily
• SQL-Optimizer techniques: filter pushdown, join-relocation
• SQL Optimizer needs statistic information about the remote table:
CREATE STATISTICS ON “SCHEMA".“VIRTUAL_TAB”(“COL1", “COL2", “COL3") TYPE HISTOGRAM;
• Virtual Tables in HANA views
• Use virtual tables in calculation views, as SDA optimizations works with calculation views only
• You might save unneeded remote accesses by using the new union node enhancements in calculation views with SPS11
• The union node enhancements allow you to define pruning rules, which may prevent remote SDA accesses - if you define unions between virtual tables and local tables
• Configure DML Mode (readonly/readwrite): if applicable, just use readonly DML-Mode as it provides performance advantages for remote select-access
SDA Adapters
• You can use HANA SDI adapters for SDA (pre-requisite: license for HANA EIM option)
• More information: http://help.sap.com/hana_options_eim?current=hana_platform
• Best practice on SDI adapter deployment: http://scn.sap.com/community/developer-center/hana/blog/2015/08/05/hana-adapter-sdk--setup
• Future support of new remote sources and their versions based on SDI adapters
