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.

Application Function Library


The SAP HANA application offers various predelivered, commonly utilized business and predictive algorithms. These functionalities are stored in the Application Function Library (AFL). The SAP HANA in-memory computing engine offers various algorithms for in-memory computing. It provides several application libraries for developers, partners, and customers who develop applications that run on SAP HANA. The libraries are linked dynamically to the SAP HANA database kernel. Customers can use these functions to speed up both implementation and performance.

Currently, all AFLs are delivered in one archive (that is, one SAR file with the name AFL<version_string>.SAR). The AFL archive is not part of the SAP HANA appliance, and must be installed separately by an administrator. Please refer to the SAP HANA server installation and update guide.
