Create Informatica Mappings From/To a JDBC Data Source for Google Translate
Informatica provides a powerful, elegant means of transporting and transforming your data. By utilizing the CData JDBC Driver for Google Translate, 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 Google Translate 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 Google Translate 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 Google Translate.
Authentication
Google Cloud Translation API requires OAuth 2.0 authentication to ensure secure access to translation services, datasets, glossaries, and adaptive MT resources. This authentication method allows you to securely connect to your Google Cloud project and manage translation resources with proper authorization.
OAuth 2.0 Setup and Configuration
Step 1: Create Google Cloud Project and Enable API
To set up OAuth authentication:
- Visit the Google Cloud Console
- Create a new project or select an existing project
- Note down your Project ID (required for all API calls)
- Navigate to "APIs & Services" > "Library"
- Search for and enable the "Cloud Translation API"
- Go to "APIs & Services" > "Credentials"
- Click "Create Credentials" and select "OAuth Client ID"
- Configure the OAuth consent screen if prompted
- Select "Desktop application" or "Web application" as appropriate
- Set the authorized redirect URI (CallbackURL)
- Copy the Client ID and Client Secret for use in your connection
Required Connection Properties
- AuthScheme: Set this to OAuth (required)
- OAuthClientId: Client ID from Google Cloud Console (required)
- OAuthClientSecret: Client secret from Google Cloud Console (required)
- CallbackURL: Redirect URI specified in your OAuth application (required)
- InitiateOAuth: Set to GETANDREFRESH for automatic token management (recommended)
- ProjectId: Your Google Cloud project ID or project number (required for queries)
Required OAuth Scopes
The Google Cloud Translation API Profile requires the following OAuth scope:
- https://www.googleapis.com/auth/cloud-translation - Full access to Cloud Translation API resources including translation, datasets, glossaries, and adaptive MT
Built-in Connection String Designer
For assistance in constructing the JDBC URL, use the connection string designer built into the Google Translate 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\GoogleTranslate.apip;AuthScheme=OAuth;InitiateOAuth=GETANDREFRESH;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackUrl=your_callback_url;
Browse Google Translate Tables
After you have added the driver JAR to the classpath and created a JDBC connection, you can now access Google Translate entities in Informatica. Follow the steps below to connect to Google Translate and browse Google Translate 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 Google Translate tables in the Data Viewer: Right-click the node for the table and then click Open. On the Data Viewer view, click Run.
Create Google Translate Data Objects
Follow the steps below to add Google Translate tables to your project:
- Select tables in Google Translate, then right-click a table in Google Translate, 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 Google Translate source to a mapping:
- In the Object Explorer, right-click your project and then click New -> Mapping.
- Expand the node for the Google Translate 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 Google Translate 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 Google Translate 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 Google Translate data, right-click in the workspace and then click Run Mapping.
