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.

Predictive Analysis Library


The Predictive Analysis Library (PAL) defines functions that can be called from within SQLscript procedures to perform analytic algorithms. It includes the following classic and universal predictive analysis algorithms in nine data mining categories:

  • Clustering

  • Association

  • Statistics

  • Classification

  • Time series

  • Social network analysis

  • Regression

  • Preprocessing

  • Miscellaneous

The algorithms in PAL were carefully selected as most of these algorithms are generally available in other database products. Also, these are frequently used and needed for SAP HANA applications.

The following are the prerequisites for using PAL:

  • Install the latest SAP HANA SPS

  • Install the AFL, which includes the PAL

  • Enable the script server in the HANA instance. SAP note 1,650,957 describes its steps.

The revision of the AFL must match the revision of SAP HANA.
