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.

You can implement row-level security with analytic privileges. You can also restrict access to selected attribute values in a given data container, such as field from attribute view, field from the attribute view used in an analytic view private dimension of the analytic view, attribute field in calculation view, combinations of the above and much more.

To create analytical privileges, perform the following:

  1. In the System view, got to the Content node, right-click on the package, and choose New | Analytical Privilege.

  2. Fill in details such as Name and Label:

  3. Then, we will have to select one of the information models that we want to use for our analytical privileges. I will use the calculation view that we just created:

    Once you are done with the preceding selection, you will get the following...
