| The Hume
		Datahub SDK is a middleware 
		toolset. The core Datahub capabilities of the toolset are:- In-memory 
		SQL database
 - Subscription 
		server
 - Message 
		system server
 - Configurable 
		Tcl/Tk interpreter
 The synergistic combination of these capabilities creates a powerful new 
		architecture for distributed applications.  The Datahub SDK enables you to easily integrate 
		SECS equipment into distributed applications. The 
		Message system capability is known as the Distributed Message Hub (DMH). 
		It 
		can be used to bridge a variety of operating systems, hardware 
		platforms, and programming  languages  to create an 
		integrated system. The Datahub capabilities are built 
		into a general purpose Tcl/Tk interpreter.  It is a tremendous 
		performance advantage to be able to install custom procedures and 
		subscription logic for execution in the Datahub process where the shared 
		SQL table data resides.  The 
		Datahub software is portable and is available for popular operating 
		systems, including Linux, HP-UX, Windows, and Solaris. Note:  for more information, click
