Modeling Best Practices in SAP Data Warehouse Cloud

Modeling in SAP Data Warehouse Cloud

Description

This repository aims to onboard new users into Modeling in SAP Data Warehouse Cloud in the most practical manner. For that you will build a real working data model, which will embrace specific features and functions. During the journey there will be additional tips and explanations on various modeling concepts.

Overview

"Learning by Doing" is the main principle of this tutorial. Discover and understand the features and modeling concepts by putting your hands on the SAP Data Warehouse Cloud application and build a fully functioning data model yourself.

The exercises are meant to be built in this particular order starting from basic concepts and diving step by step into deeper advanced features while progressing with the exercises. The exercises are also based on each other. Hence, they prerequisite each other.

The tutorial comes along with a sample dataset (CSV files), so that only a minimalistic system setup is required, without any complex source system connection and data ingestion processing activities (Off course, it is still highly recommended to get yourself familiar with those features, especially when you run SAP Data Warehouse Cloud in a full enterprise and productive manner). For this tutorial working with the prepared sample datasets serves the purpose.

In general, you should be aware that SAP Data Warehouse constantly updates and delivers new features. That means, that some of the described features might be outdated and look differently than from your latest version (for that please check regularly the "What's New" website and the SAP Roadmaps in the links section below).

That being said, I hope this tutorial will give you a solid understanding and insights into the fundamental modeling principles of SAP Data Warehouse Cloud on which you can build upon in the future.

And now enjoy the tutorial ;)

Pre-requisites

SAP Data Warehouse Cloud

Before you can start with the exercises, please make sure to get a running SAP Data Warehouse Cloud tenant with the latest updates. For that you can apply for a 30-Days free Trial Tenant under the following link:

• https://www.sap.com/products/data-warehouse-cloud/trial.html
• https://saphanajourney.com/data-warehouse-cloud/trial/

SAP Analytics Cloud

Optionally you will need also a running SAP Analytics Cloud (SAC), which is required to build the Stories, Dashboards and Visualization on top of the SAP Data Warehouse Models. In case you are not interested, you can skip the exercises with the SAC part. However, it is highly recommended to walk through these exercises as well, to see how the individual features are consumed from the client side. For that, you can request an SAC trial tenant from the following link:
