| Summary: | 碩士 === 國立臺灣科技大學 === 營建工程系 === 95 === An information system, based on service-oriented architecture, for disaster reduction and recovery was constructed and studied in this research. In order to facilitate information exchange and system integration between the constructed system and other systems, basic functions of the constructed information system are exposed through web services, one of the key technology in the era of Web 2.0.
The software platform used in the development of the information system is LAMP (Linux, Apache, MySQL, and PHP) with the assistance of NuSOAP class library. The overall system architecture of the information system can be considered as a 4-tier information system incorporating the following tiers: web browser, web server, web service, and database.
In this study, an information system was constructed to complement the existing information system for disaster reduction and recovery for Keelung City on the following three management functions: 1) projects and their associated events; 2) standard operation procedure, including viewing and checklisting; and 3) resource usage for disaster recovery. These functions were identified through analyzing the existing system. These functions were implemented through standardized web services, and could therefore be integrated easily into the existing information system written in JSP or any other software environment with facilities to access SOAP web services. Finally, the influence of network configurations on the performance of service oriented architectured information systems based on SOAP web services was studied. The information system developed was deployed as client-server configuration (by fusing web server tier and web service tier) and compared with the 4-tier configuration. The study helps on the design of IT infrastructure for information systems based service-oriented architecture and SOAP web services
