Create Informatica Mappings From/To an ODBC Data Source for Open Exchange Rates

Create an ODBC connection to Open Exchange Rates in Informatica and browse and transfer Open Exchange Rates data.

Informatica provides a powerful, elegant means of transporting and transforming your data. By utilizing the CData ODBC Driver for Open Exchange Rates, 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 Open Exchange Rates data in Informatica PowerCenter.

Connect to Open Exchange Rates as an ODBC Data Source

Information for connecting to Open Exchange Rates follows, along with different instructions for configuring a DSN in Windows and Linux environments.

The Open Exchange Rates API supports basic authentication with an App Id. After you register, your App Id is displayed in your account dashboard. Set this to the AppId connection property.

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 Open Exchange Rates 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 OpenExchangeRates Source] Driver = CData ODBC Driver for Open Exchange Rates Description = My Description AppId = abc1234

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