RF-TP™ Server Overview

The server component of the RF-TP™ software runs on a Windows 95/98/NT/ME/XP system. It is implemented as a C++ program supporting multiple TCP/IP connections to Symbol hand held computers over a Spectrum 24® radio network.

Applications can be implemented without adding any custom functionality to the standard version of the server.

A set of abstract custom classes allows special functionality to be added to the server. A full visual development environment supports the implementation and testing of these facilities.

User Interface Independence

The client-server model implemented by the RF-TP™ software places responsibility for the user interface in the client application. Different client environments can share the same server.

This also greatly reduces radio traffic as relatively few messages are passed to the server, usually just those requiring database access or use of shared resources, such as printers.

ODBC and SQL Access

The client-server model implemented by the RF-TP™ software places responsibility for the database access and update in the server application. The design and access for single or multiple databases is retained within the server software.

Typically, the client software sends a simple message to the server requesting verification of a field, retrieval of one or more records, or a database update. The server software formats and issues the ODBC or SQL commands, and then transmits the reply to the client in a simple response message.

The ODBC implementation uses externally defined linkages. This allows a custom server application to be developed and tested on (for example) a Microsoft Access database on the development computer, and then deployed, without recompilation, using (for example) a remote Oracle database on a UNIX mainframe.
