Object-Oriented architectural support for developing complex systems

Object-oriented software evolves over time, and it would be ideal if we could capture the persistent parts of the software early on and then derive the transient versions of the software from the persistent parts. Capturing the persistent parts of the software allows us to better maintain the integrity of the program during its evolution. This is the goal of software architecture. In this paper, we emphasize an approach called O3ML (Operational Object-Oriented Modeling Language) to model complex software systems using a sound software architecture which is centered on the creation of a system prototype with integrated design requirements and a simulation framework. This methodology supports the prototyping of complex computer-based systems by providing: (a) a multi-domain approach to capture the architectural complexity of real-world systems; and (b) a mechanism for the simulation of the conceptual, functional and implementation features of the design and the user requirements
