Conceptual Overview of the Datahub

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.
