The seller performs some action
that results in the creation of data for the buyer, such as a purchase order
The data created by the
supplier is deposited into a specific directory on the extranet application server.
There are two options for how
the intranet and extranet gateways communicate.
The extranet gateway has a
"listener" software function that polls directories continuously.
When the presence of a new file is detected, the listener launches the
connection to the intranet gateway and transmits the file to a directory
on the intranet gateway that is polled by its listener.
The intranet gateway has a
"checker" software function that connects at regular intervals to the
extranet gateway server and polls directories. When the presence of
a file on the extranet gateway server is detected, the data is pulled to
the intranet gateway server, and deposited in a directory on the intranet
gateway that is polled by its listener.
gateway uses the identifier in the web application file to retrieve information
about what to do with the file.
The OAGI data is translated into
The file should be enveloped for
the internal application, including data for identifying the sender, the
type of message contained in the file, and the internal destination computer
If the application and the
gateway are on different machines, an internal communications network is used
to transmit the application data file from the gateway to the application
The application receives and processes the data. The
processing can be anything from just storing the data in the application for
reporting to updating data bases and triggering other applications processes.
