SPATIO-TEMPORAL UML METHODOLOGY: EXTENDING AND INTEGRATING EXISTING OBJECT-ORIENTED METHODS TO DEVELOP SPATIO-TEMPORAL DATABASES

摘要

Object-oriented methods seem to handle well the complexity associated with developing spatio-temporal software systems. In recent years, a growing number of software systems are being developed within the object-oriented paradigm. This paper presents the extension and integration of existing methods to provide an object-oriented methodology that facilitates the development of spatio-temporal software systems. The Unified Modeling Language (UML) is extended with spatial and temporal semantics to allow the effective modeling of a spatio-temporal database during the analysis phase of software development. ArcInfo UML, that is, the Unified Modeling Language extended by Arclnfo structures, is used to facilitate the modeling of a system during the design phase. Arclnfo is used as the implementation platform of the spatio-temporal database. A UML CASH tool (Microsoft Visio) will be used during analysis, design and Arclnfo database schema generation. Development will be lead by the Spatio-temporal UML process, that is, the Booch process extended to address spatial and spatiotemporal concerns.
