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.

  • Text Analysis: This is the process of analyzing unstructured text, extracting relevant information, and then transforming this information into structure information that can be leveraged in different ways. The scripts provide additional possibilities to analyze strings or large text columns by providing analysis rules for many industries in many languages for SAP HANA.

  • Full Text Search: This capability of HANA helps to speed up search capabilities within large amounts of text data significantly. The primary function of Full Text Search is to optimize linguistic searches.

  • Fuzzy Search: This functionality enables us to find strings that match a pattern approximately (rather than exactly). It's a fault-tolerant search, meaning that a query returns records even if the search term contains additional or missing...
