Sharing Platform Based On The The Dssa Nanjing "digital Real Estate Of Gis Network

With about thirty years' development, GIS technology becomes one of the main parts of Information Technology, involve into everywhere of people's live, and the Application of GIS turn from map-center to management-center step by step too. Recognizing and tracking this intendancy, studying the characteristics of this new style GIS application, is very important to improve the depth and width of GIS application.Compare with the traditional GIS system of map-center, the new GIS system of management-center have a smaller differences with other enterprise system such as MIS and OA. On the other hand, they appear a relation of Integration and corporation, and finish a concrete work together. The characteristic of the new management-center GIS system makes it very different form the traditional map-center GIS system in the construction method, especially at the architectures, such as platform-independent, configuration, and scalable.The software architecture is the most advance style of software reuse, is the development framework based on software component with directive able. The software architecture defines the architecture of software from an advance view, and defines the relationship of system component, so giving a road to implement large scale software reuse. Three is still a lot of difficulty on the study of common software architecture, so most study on software architecture is about specific application domain, named Domain Specific Software Architecture (DSSA). In developing engineer, DSSA have an extensive application.Therefore, study on the software characteristic of management-center GIS application system, especially the Software Architecture model of this domain, and using it to direct the development of the GIS application system of this domain, will improve the developing efficient of application system in this domain.This thesis use DSSA model as directive thinking, use Nanjing "Digital House" GIS network sharing platform as study target, integrate with the development of Nanjing "Digital House" Project, analysis the common software architecture of Nanjing "Digital House" GIS network sharing platform software, based on this common software system architecture designed and implemented Nanjing "Digital House" GIS network sharing platform software, do a test on theprocess of application DSSA in GIS developing engineer.
