The
Gateway Server is designed to deal with
the interface
of the legacy systems where accessing
to the database of these systems is somehow difficult
or not possible. To provide an easier and alternate
way of interfacing with these system, the Gateway
Server will connect to these system as a Telnet client
to perform transactions and getting the results and
return them back to the Server component that initiates
them.
By using the Gateway Server, you can ensure a higher
integrity of sharing information among the systems and avoid
touching the programming codes of these legacy systems.
The common usage of the Gateway Server may be most useful
when interfacing with Applications that are running in
AS/400 or other UNIX Host operating systems like WorkStream,
ERP, MRP and etc.
Besides providing the interface, the Gateway Server can
also perform screen re-formatting and input sequencing to
handle the difference between the size of the display window
of 80X40 and 16X4. This feature will allow the user
prompting of the legacy system to be re-formatted or
abbreviated to suit the smaller LCD display window of most
terminals. Multiple input on a larger screen can be
separated into input sequence and be displayed one by one on
the smaller display.
