1.3 About Oracle Database Gateway for SQL Server

The capabilities, SQL mappings, data type conversions, and interface to the remote non-Oracle system are contained in the gateway.

The gateway interacts with Heterogeneous Services to provide the transparent connectivity between Oracle and non-Oracle systems.

The gateway can be installed on any machine independent of the Oracle or non-Oracle database. It can be the same machine as the Oracle database or on the same machine as the SQL Server database or on a third machine as a standalone.
