The Oracle Database Gateway for ODBC enables Oracle client applications to access non-Oracle data stored in databases that support a compatible Windows ODBC driver. Although the data remains in its native storage, it appears to Oracle applications as if it resides in a single, local Oracle database.
This section explains how to install the Oracle Database Gateway, which can then be integrated with the ODBC Driver for Salesforce to access different kinds of data sources, including Salesforce data.
