Real Time Analytics with SAP Hana

By: Vinay Singh

Overview of this book

SAP HANA is an in-memory database created by SAP. SAP HANA breaks traditional database barriers to simplify IT landscapes, eliminating data preparation, pre-aggregation, and tuning. SAP HANA and in-memory computing allow you to instantly access huge volumes of structured and unstructured data, including text data, from different sources. Starting with data modeling, this fast-paced guide shows you how to add a system to SAP HANA Studio, create a schema, packages, and delivery unit. Moving on, you’ll get an understanding of real-time replication via SLT and learn how to use SAP HANA Studio to perform this. We’ll also have a quick look at SAP Business Object DATA service and SAP Direct Extractor for Data Load. After that, you will learn to create HANA artifacts—Analytical Privileges and Calculation View. At the end of the book, we will explore the SMART DATA access option and AFL library, and finally deliver pre-packaged functionality that can be used to build information models faster and easier.

Loading data with SAP Direct Extractor


DXC (Direct Extractor) is a batch-driven data acquisition technique, and a form of extracting, transforming, and loading (ETL) data though its transformation capabilities are limited to user exit for extraction.

The main idea behind DXC is to use existing data models, thereby lowering the Total cost of Ownership (TCO).

Some of the salient features of DXC are:

  • Leverage pre-existing foundational data models of SAP Business Suite

  • Significantly reduces the complexity of data modeling tasks in SAP HANA

  • Reduces the timelines for SAP HANA implementation projects

  • Provides semantically rich data from SAP Business Suite to SAP HANA

  • Many of the extractors have already got built in application logic to give the data the appropriate contextual meaning

  • Reuses an existing proprietary extraction, transformation, and loading mechanism

  • It is built into SAP Business Suite systems over a simple HTTP(s) connection to SAP HANA

  • No additional server or application is needed in the...
