Create Informatica Mappings From/To a JDBC Data Source for Nuclia
Informatica provides a powerful, elegant means of transporting and transforming your data. By utilizing the CData JDBC Driver for Nuclia, you are gaining access to a driver based on industry-proven standards that integrates seamlessly with Informatica's powerful data transportation and manipulation features. This tutorial shows how to transfer and browse Nuclia data in Informatica PowerCenter.
Deploy the Driver
To deploy the driver to the Informatica PowerCenter server, copy the CData JAR and .lic file, located in the lib subfolder in the installation directory, to the following folder: Informatica-installation-directory\services\shared\jars\thirdparty.
To work with Nuclia data in the Developer tool, you will need to copy the CData JAR and .lic file, located in the lib subfolder in the installation directory, into the following folders:
- Informatica-installation-directory\client\externaljdbcjars
- Informatica-installation-directory\externaljdbcjars
Create the JDBC Connection
Follow the steps below to connect from Informatica Developer:
- In the Connection Explorer pane, right-click your domain and click Create a Connection.
- In the New Database Connection wizard that is displayed, enter a name and Id for the connection and in the Type menu select JDBC.
- In the JDBC Driver Class Name property, enter:
cdata.jdbc.api.APIDriver
- In the Connection String property, enter the JDBC URL, using the connection properties for Nuclia.
Using API Key Authentication
Nuclia uses API key authentication for accessing Knowledge Box data. To obtain an API key:
- Log in to the Nuclia Cloud Dashboard at https://nuclia.cloud
- Navigate to your Knowledge Box settings
- Go to the Service Accounts section
- 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.
Built-in Connection String Designer
For assistance in constructing the JDBC URL, use the connection string designer built into the Nuclia JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.
java -jar cdata.jdbc.api.jar
Fill in the connection properties and copy the connection string to the clipboard.
A typical connection string is below:
jdbc:api:Profile=C:\profiles\Nuclia.apip;AuthScheme=APIKey;APIKey=your_service_account_key;KbId=your_kb_uuid;Zone=aws-us-east-2-1;
Browse Nuclia Tables
After you have added the driver JAR to the classpath and created a JDBC connection, you can now access Nuclia entities in Informatica. Follow the steps below to connect to Nuclia and browse Nuclia tables:
- Connect to your repository.
- In the Connection Explorer, right-click the connection and click Connect.
- Clear the Show Default Schema Only option.
You can now browse Nuclia tables in the Data Viewer: Right-click the node for the table and then click Open. On the Data Viewer view, click Run.
Create Nuclia Data Objects
Follow the steps below to add Nuclia tables to your project:
- Select tables in Nuclia, then right-click a table in Nuclia, and click Add to Project.
- In the resulting dialog, select the option to create a data object for each resource.
- In the Select Location dialog, select your project.
Create a Mapping
Follow the steps below to add the Nuclia source to a mapping:
- In the Object Explorer, right-click your project and then click New -> Mapping.
- Expand the node for the Nuclia connection and then drag the data object for the table onto the editor.
- In the dialog that appears, select the Read option.
Follow the steps below to map Nuclia columns to a flat file:
- In the Object Explorer, right-click your project and then click New -> Data Object.
- Select Flat File Data Object -> Create as Empty -> Fixed Width.
- In the properties for the Nuclia object, select the rows you want, right-click, and then click copy. Paste the rows into the flat file properties.
- Drag the flat file data object onto the mapping. In the dialog that appears, select the Write option.
- Click and drag to connect columns.
To transfer Nuclia data, right-click in the workspace and then click Run Mapping.
