Create an ODBC connection to Azure Data Catalog in Informatica and browse and transfer Azure Data Catalog data.

Informatica provides a powerful, elegant means of transporting and transforming your data. By utilizing the CData ODBC Driver for Azure Data Catalog, 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 Azure Data Catalog data in Informatica PowerCenter.

Connect to Azure Data Catalog as an ODBC Data Source

Information for connecting to Azure Data Catalog follows, along with different instructions for configuring a DSN in Windows and Linux environments.

You can optionally set the following to read the different catalog data returned from Azure Data Catalog.

    CatalogName: Set this to the CatalogName associated with your Azure Data Catalog. To get your Catalog name, navigate to your Azure Portal home page > Data Catalog > Catalog Name

Connect Using OAuth Authentication

You must use OAuth to authenticate with Azure Data Catalog. OAuth requires the authenticating user to interact with Azure Data Catalog using the browser. For more information, refer to the OAuth section in the help documentation.

Windows

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.

Linux

If you are installing the CData ODBC Driver for Azure Data Catalog in a Linux environment, the driver installation predefines a system DSN. You can modify the DSN by editing the system data sources file (/etc/odbc.ini) and defining the required connection properties.

/etc/odbc.ini

[CData AzureDataCatalog Source] Driver = CData ODBC Driver for Azure Data Catalog Description = My Description

For specific information on using these configuration files, please refer to the help documentation (installed and found online).
