This appendix presents the software architecture for the Orbit Analysis application. The contents of this appendix are as follows:
* assumptions upon which the architecture was developed
* DFDs that indicate the functional breakdown of the Orbit Analysis area and the data that flows into and out of Orbit and between the functions within Orbit Analysis.
* a CFD that indicates the temporal dependencies of the functions in this area
* benchmarks used to evaluate the impact of any driving performance requirements
