MQSeries is a messaging system middleware that connects heterogeneous systems and applications through a common mechanism. The Application Programming Interface, MQI, provided with MQSeries is cross-platform and implemented in many programming languages. The D3 MQSeries Server Interface is Rocket’s implementation of the MQSeries API in FlashBASIC. This allows BASIC programmers to interface their D3 applications with any platforms and applications that support MQSeries. MQSeries is the industry standard for messaging systems. The ability for D3 to use the MQSeries MQI library is critical to many business applications and provides solutions that would no be possible otherwise.
