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.

Attribute views are dimensions, similar to BW characteristics. They are synonymous to master data and can be reused and shared (in analytical and calculation views). Having said that, attribute view is not restricted to master data, but can be created on transactional data as well.

Let's learn how to create it. While creating an attribute view, we have following choice:

  • Using single or multiple tables as data foundation

  • Using existing attribute view

Following are the prerequisites:

  • Tables should exist with data, which we will use for data foundation

  • Package should exist, under which the view would be created

For us, we already have met the prerequisite. In Chapter 2, SAP HANA Data Modeling Approach, we learned how to create Package and in Chapter 3, Different Ways of SAP HANA Data Load, we saw creation(replication) of a table.

Let's create attribute view step by step, as follows:

  1. In the System view, right-click on Package | New | Attribute View.

  2. Fill the technical name (I...
