Abstract: This document presents the software requirements analysis for Travel, Version 1.0, a component of the Corporate Business Application Software System (C-BASS) that automates travel requests for the U.S. Army Research Laboratory (ARL). The document follows the process of structured analysis, or step wise refinement of requirements, as applied to the development of a prototype for the full version of Travel. The environmental model includes a high level system description, followed by a context diagram and a list of events to which the system must respond. The behavioral model includes a data flow diagram (DFD) for each of the four Travel 1.0 subsystems. From this representation, the basic functional specifications are derived and represented in structured English (or program design language). The final segment of the document includes a data dictionary that defines all data and control items.
