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.

Summary


In this chapter, you learned about the different data loading methods and salient features of each. We started the chapter with the simplest method of uploading via flat file and then progressed to real-time replication. One of the major time-consuming activities in reporting is data loading, so choosing the right method as per your requirements and infrastructure becomes of paramount importance. You learned about all the available tools and methods that can be used or are being used. On one side, you learned about Smart Data Access, which gave us the concept of virtual tables without actually copying data into SAP HANA. On the other side, you saw how SAP Replication Server helps with multisite availability using log-based replication. We also showed you in detail how SLT works and can be used for real-time replication.

In the next chapter, you will learn how to create HANA artifacts—attribute view and analytical view. You will learn about various other components involved during...
