HPCC Systems Reporting and Star Schemas in OBIEE

Create a star schema that shows perspectives on HPCC Systems facts in real time.

The CData ODBC Driver for HPCC Systems is a standard database driver that can integrate real-time access to HPCC Systems data into your data warehouse or directly into your reporting tool. This article shows how to bypass the data warehouse and import operational HPCC Systems data into Oracle Business Intelligence Enterprise Edition (OBIEE).

See the knowledge base for ODBC integrations with ETL tools like Informatica PowerCenter. For an ETL solution into Oracle Warehouse Builder, use the driver with the Oracle ODBC Gateway to Access HPCC Systems Data as a Remote Oracle Database.

Connect to HPCC Systems as an ODBC Data Source

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

To connect, set the following connection properties: Set URL to the machine name or IP address of the server and the port the server is running on, for example, https://server:port. The User and Password are required to authenticate to the HPCC Systems cluster specified in the URL. Note that LDAP authentication is not currently supported by our ODBC driver.

Set Version to the WsSQL Web server version. Note that if you have not already done so, you will need to install the WsSQL service on the HPCC Systems server. The WsSQL Web service is used to interact with the underlying HPCC Systems platform.

Set Cluster to the target cluster.

When you configure the DSN, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

Import HPCC Systems Metadata

Follow the steps below to use the OBIEE Client Tools to import HPCC Systems metadata into an OBIEE repository. You can then integrate HPCC Systems data into your business models.

  1. Open the Administration Tool and click File -> New Repository.

  2. In the Connection Type menu, select ODBC 3.5 and select the CData DSN.
  3. Select the metadata types you want to import under the Relational Sources option and then select HPCC Systems tables.
You can now create star schemas based on HPCC Systems tables:
