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.

Chapter 1. Kickoff – Before We Start

This chapter intends to provide context and background to set the base with which we can manipulate the datasets to be used for data modeling. This section tries to act as a refresher that should help you understand and pick up modeling topics faster in upcoming chapters.

We start the chapter with Structured Query Language (SQL)—how we can use it for controlling and manipulating the SAP HANA database objects and data. Then we move on to create SQLscript and learn how to use it effectively. We will also discuss creation and call of procedure step by step in this chapter, which is a good tool for the upcoming topics. We will end the chapter with a detailed discussion on JOINS and how it can be used for connecting tables in SAP HANA.

After completing this chapter you will be able to:

  • Understand and use SAP HANA SQL statements

  • Create SQLscript and use it

  • Create and call a procedure

  • Connect tables using SAP HANA specific JOINS
