The gateway can be included in a variety of configurations, each to suit the needs of a particular user community. The following diagrams illustrate three sample systems.

This diagram illustrates a local configuration:

*Client: OpenROAD, JDBC, ODBC, OpenAPI, Embedded SQL

This diagram illustrates a possible remote access configuration:

*Client: OpenROAD, JDBC, ODBC, OpenAPI, Embedded SQL

This diagram illustrates a remote configuration:

*Client:  OpenROAD, JDBC, ODBC, OpenAPI, Embedded SQL
  Host Net:  (1) Oracle SQL/Net
  (2) Microsoft SQL Server Remote Access

Other combinations of the tools are possible, with various components being either local or remote. In the preceding diagrams, each of these systems could contain anything from a personal computer to a mainframe-as long as the software component is available for that platform. Because the Ingres tools, gateways, and communication components are available on different hardware platforms, many configurations are possible.
