Resumen
Dynamic object technology enables applications to be modified and enhanced during development and runtime without access to source code. In this article, the author discuss the specifics of the important role that dynamic objects play in Blackboard Technology's software products and in one of the applications built using them: the PLAN component of the Mission Control System for the Canadian Space Agency's RADARSTAT-1 earth observation satellite. Blackboard applications, such as those built with Generic Blackboard Builder (GBB) , benefit greatly from dynamic object capabilities. The most successful blackboard applications are never truly "completed." They continue to grow and evolve in tandem with the enterprises they serve. The RADARSTAT-1 experience is but one example of the successful use of dynamic objects and GBB. GBB itself would probably not exist without dynamic objects. A more static product would have been far more expensive to develop and more difficult to use, and the resulting applications would be less flexible and adaptable to change. GBB's use of dynamic objects give GBB-based applications, the flexibility needed to operate effectively in fast-paced, open, dynamic environments.
