Based on the research of relative achievements, the paper completely discuss the distributed application and the charact- eristic and the technology of Web Services, introduce some solution based on Web of a few mainly distributed technologies which are used in commercial software today, discuss the trend of distributed system based on Web Services on .NET Framework. The paper also discusses GIS Web Services which is adopted by the system. It analyses in detail GIS Web Services' s construction model, and technical features, especially discusses the task-background, the systemic radical frame design, the data-base design, the technology design, the performance realization about military mapping and surveying data-management system which is based on ADO.NET and GIS Web Services. |
