Who This Book Is For

If you are a SAP HANA data modeler, developer, implementation/migration consultant, project manager, or architect who is responsible for implementing/migrating to SAP HANA, then this book is for you.

What You Will Learn

  • Get to grips with the basic building blocks of Analytics/Data models in the SAP HANA environment.
  • Discover various schemas, modeling principles, Joins, and the architecture of the SAP HANA engine.
  • Build data models and artifacts in Sap HANA Studio.
  • Design decision tables and understand the concept of transport management in the SAP HANA landscape.

  • Explore full-text search and fuzzy search in SAP HANA.
  • Create your own scenarios and use cases using sample data and code.

In Detail

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.

Style and approach

This is an easy-to-follow, step-by-step, rapid guide to help you learn analytics in SAP HANA through ample hands-on exercises and use case scenarios.
