CData Connect



Use CData Connect Cloud to create a virtual MySQL Database for SAP HANA data and build visualizations and dashbaords from SAP HANA data in Redash.

Redash lets you connect and query your data sources, build dashboards to visualize data and share them with your company. When paired with CData Connect Cloud, you get instant, cloud-to-cloud access to SAP HANA data for visualizations, dashboards, and more. This article shows how to create a virtual database for SAP HANA and build visualizations from SAP HANA data in Redash.

CData Connect Cloud provides a pure MySQL, cloud-to-cloud interface for SAP HANA, allowing you to easily build visualizations from SAP HANA data in Redash. As you build visualizations, Redash generates SQL queries to gather data. Using optimized data processing out of the box, CData Connect Cloud pushes all supported SQL operations (filters, JOINs, etc) directly to SAP HANA, leveraging server-side processing to quickly return SAP HANA data.

Create a Virtual MySQL Database for SAP HANA Data

CData Connect Cloud uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

  1. Log into Connect Cloud and click Databases.
  2. Select "SAP HANA" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to SAP HANA.

    Set the Server, Database and Port properties to specify the address of your SAP Hana database to interact with. Set the User and the Password properties to authenticate to the server.

  4. Click Test Database.
  5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

With the virtual database created, you are ready to build visualizations in Tableau Online.

Visualize SAP HANA Data in Tableau Online

The steps below outline creating a new data source in Redash based on the virtual SAP HANA database in Connect Cloud and building a simple visualization from the data.

Create a New Data Source

  1. Log into Redash, click on your profile and click "Data Sources"
  2. Click the " New Data Source" button
  3. Select "MySQL (Amazon RDS)" as the Data Source Type (CData Connect uses SSL, which the standard MySQL connection in Redash does not support)
  4. On the configuration tab, set the following properties:
    • Name: Name the data source (e.g. SAP HANA (CData Connect))
    • Host: The full URL to your CData Connect instance (e.g. https://myinstance.cdatacloud.net)
    • Port: The port of the CData Connect MySQL endpoint (e.g. 3306)
    • User: A CData Connect user
    • Password: The password for the above user
    • Database name: The name of the virtual database for SAP HANA (e.g. SAPHANA1)
    • Click the checkbox to Use SSQL
  5. Click Create
  6. Click the "Test Connection" button to ensure you have configured the connection properly

With the new Data Source created, we are ready to visualize our SAP HANA data.

Create a SAP HANA Data Visualization

  1. Click Create -> New Query
  2. Select the newly created Data Source (you can explore the data structure in the New Query wizard)
  3. Write a SQL statement to retrieve the data, for example:
    SELECT Name, OwnerId FROM Buckets WHERE Name = 'TestBucket'
  4. Click the "Execute" button to load SAP HANA data into Redash via CData Connect
  5. Use the Visualization Editor to create and analyze graphs from SAP HANA data
  6. You can schedule the query to refresh and update the visualization periodically

SQL Access to SAP HANA Data from Cloud Applications

At this point, you have a direct, cloud-to-cloud connection to SAP HANA data from Redash. You can create new visualizations, build dashboards, and more.
