Nuclia Reporting and Star Schemas in OBIEE

The CData ODBC Driver for Nuclia is a standard database driver that can integrate real-time access to Nuclia data into your data warehouse or directly into your reporting tool. This article shows how to bypass the data warehouse and import operational Nuclia 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 Nuclia Data as a Remote Oracle Database.

Connect to Nuclia 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.

Using API Key Authentication

Nuclia uses API key authentication for accessing Knowledge Box data. To obtain an API key:

1. Log in to the Nuclia Cloud Dashboard at https://nuclia.cloud
2. Navigate to your Knowledge Box settings
3. Go to the Service Accounts section
4. Create a new service account or copy an existing API key

After obtaining your API key, set the following connection properties:

• AuthScheme: Set this to APIKey.
• APIKey: Set this to your Nuclia service account API key.
• KbId: Set this to your Knowledge Box UUID.
• Zone: Set this to your Nuclia deployment zone (e.g., aws-us-east-2-1).

Example Connection String

Profile=C:\profiles\Nuclia.apip;AuthScheme=APIKey;APIKey=your_service_account_key;KbId=your_kb_uuid;Zone=aws-us-east-2-1;

Connecting to Nuclia

Once the authentication is configured, you can connect to Nuclia and query data from any of the available tables such as Resources, KnowledgeBox, LabelSets, and ProcessingStatus.

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 Nuclia Metadata

Follow the steps below to use the OBIEE Client Tools to import Nuclia metadata into an OBIEE repository. You can then integrate Nuclia 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 Nuclia tables.
