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.
Session Agenda • Introduction • HANA Overview • SAP University Alliance: Student Exercise and Demo: BO Explorer on HANA • Overview of Extract, Transform and Load (ETL) into HANA • SAP University Alliance: Student Exercise – Step-by-Step • Demo: BI 4.1 (new) on HANA • Where to Find More Information • Questions and Answers
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 complexrequirements than analytic views • Can include both tables and views

Exercise #1 Using SAP HANA and BO Explorer In this first exercise, the students access SAP HANA through an Information Space
Some of the Different BusinessObjects BI tools that can access HANA

Trigger Based Replication SAP LT Replication Server Source System SAP HANA DBconnection RFCconnection 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 Source Target 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
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 Table‘s metadata Import datastore tables 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)
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

Student Case Study Example In this HANA case study, the students load data to SAP HANA Then they create attribute and analytical views Finally, they deploy it to BO Explorer
Result Student’s do the same for Products and sales flat files
