Unlocking Advanced Analytics: Bringing SAP Datasphere Views to Databricks with SAP HANA Cloud JDBC

Introduction:

SAP Datasphere is a powerful platform that allows organizations to create and manage data models, views, and integrations. On the other hand, Databricks is a widely used data analytics and machine learning platform. In this blog post, we will explore how to bring SAP Datasphere views to Databricks using SAP HANA Cloud JDBC.

Prerequisites: Before we begin, make sure you have the following prerequisites in place:

1. Set up an SAP Datasphere Trial Account: Obtain access to SAP Datasphere by creating a trial account.
2. Create a Space and Add a Connection: Create a space in SAP Datasphere and establish a connection to your SAP S/4 HANA system.
3. Add a Database User: Create a database user in your SAP Datasphere space.
4. Databricks Trial Account: Obtain access to Databricks by creating a trial account.

Step 1: Importing Tables to SAP Datasphere

Once you have set up your SAP Datasphere account, space, connection, and database user, import all the required tables into your SAP Datasphere space using the data builder tool.

After importing the tables, load a snapshot (Table Replication) for the tables you want to persist. For tables that change rapidly in the operational system, you can keep them federated as remote tables. This can be done using the Data Integration Monitor.

Step 2: Creating Dimension Views and Relational Dataset Views In SAP Datasphere

To enable seamless data consumption, SAP Datasphere allows you to create dimension views and relational dataset views using its intuitive graphical views in the Data Builder tool. Leverage these powerful capabilities to model and define your data views.

Step 3: Add an IP address range to IP Allowlist

To connect to the SAP HANA database from Databricks, you need to allow IPs to connect to the database.

Also, ensure that the database user has the necessary read/write privileges.

Step 4: Establishing a JDBC Connection to Databricks

To establish a JDBC connection to Databricks, you will need the SAP HANA JDBC driver. Download the driver file (“ngdbc”) from the SAP Support Launchpad or SAP Development Tools. Once downloaded, upload the driver file to Azure Databricks.
