| Summary: | 碩士 === 國立政治大學 === 資訊科學學系 === 96 === For the wide range of services and diversified application systems in operation in large government agencies or businesses, information sharing among systems is becoming increasingly necessary (such as users’ personal data on different systems). When it comes to managing shared information, lacking an effective system and flow process makes synchronized operation or access to information a less successful task. The research in question brings up a centralized control specification as solution to the issue through sound management and technique. In the research, uniform information starts from uniform data specification. At the same time, a single data source is set together with a plurality of data destinations.
In the research in question, information specification is made based on Web Service WDSL language characteristics. WSDL refers to a kind of self-descriptive information specification that is operational across different platforms for successful integration of systems developed in different program languages. In this research, it is believed, since information sharing is a common behavior; there must be an information specification guard responsible for the scheming, maintenance and management of the same. On the other hand, regular meetings on information sharing must be convened for discussion of the scope. In the system made available in this research, the information specification guard makes the WSDL information sharing specification for operation by information providers and use by the system developers once publicized.We also Implement a tool to generate WSDL.
In this research, it is expected, through the centralized managament of the specifications for shared services, the system developers could have their roles and responsibilities properly defined. By means of sorting out the sources, system integration or data exchange could become much easier and development could become successful more rapidly as a way to reduce the cost involved in system development and eventually, allow those who are willing to bid in public projects come to participate without much concern. If so, bidding by private sector could be an easy task.
