Report
Session 4: The HANA Curriculum
and Demos
Dr. Bjarne Berg
Associate professor Computer Science
Lenoir-Rhyne University
Introduction
This last session is more technical as we explore what
ETL options HANA has, what applications exists and
review some core exercises students in the SAP
University Alliance completes as part of their curriculum.
We also see demos of BO Explorer on SAP HANA and a
demo of the new BusinessObjects BI 4.1 tool suite and
integrated BI environment on-top of HANA
We end with an overview of where you can get more
information about HANA and have a quick round with
questions and answers.

HANA – The Detailed Architecture
Modeling in SAP HANA
HANA Applications Overview and Discussion
Views in SAP HANA
•
Attribute views
 Represent master data (attributes,
texts, hierarchies)
 Provide reusable dimensions
for analytic and calculation views
•
Analytic views
 Join facts with relevant attribute
dimensions
•
Calculation views
 Address more complex
requirements than analytic views
 Can include both tables and views

Data Provisioning
Trigger Based Replication
•
SAP LT Replication Server
 Trigger-based concept that only considers the tables
relevant for data replication
 Allows real-time (and scheduled) data replication from SAP
ERP Systems and non-SAP systems (SAP supported
databases only) into HANA
 Based on the SLO (System Landscape Optimization)
technology

Data flows Vs. Workflows
•
Data flows



•
Extract, transform and load data (ETL
process)
Determines the flow of data – from the
source to the target
Similar to SAP BW transformations with
data source and data target
Workflows




Optional objects
Organize data flows
Define the decision-making process to
execute data flows and organizes data flows
Similar to SAP BW process chains for
automation of complex schedules
Source
Target
Definitions and Metadata
•
•
•
Datastores:
 Provide the logical connection to a database (must be
specified for each source and target database)
 Are used to import metadata for source and target databases
 Are used to read data from source tables and load data to
target tables
Metadata includes:
 Database tables: Table name, Column names, Column data
types, Primary key columns, Table attributes
 RDBMS functions
 Application-specific data structures
Connection metadata is defined in the object library as
Datastores (for tables) and file formats (for flat files)
Importing Metadata from HANA
•
•
Import the metadata of the database tables (e.g. master data and
transaction data tables), which should be populated at the end of the
ETL process
Examples:


Customer attributes table (master data)
Sales data table (transaction data)
Table‘s

Creating a Dataflow
Query mapping and transformations
•
•
The query transform enables you to select data from a source,
filter or reformat the data and move it to the target
You need to create a relationship between the input and output
schemas for the data to move from the source to the target
