Image Number 13 for United States Patent #5301270.
A computer-assisted software engineering system facilitates the design, implementation, and execution of applications in cooperative processing environments. Design tools create, store, retrieve, and edit system specifications in a repository. Construction tools generate applications from the systems specification created by the design tools. A run-time execution architecture is provided for executing the applications on a plurality of computer hardware platforms. The run-time execution architecture includes pre-programmed presentation services for interacting with the user and pre-programmed distribution services for routing and transferring messages.
