Research For The Technology Of Constructing Digital Border-land Service Platform

Digital Border-land service platform is a business platform with the realization of interactive applications of geographic information and geoanalysis. Digital Border-land service platform integrates relevant applications and services including geo-information and geographical information, and forms a platform of multiple service mechanism. This paper tried the loose integration of applications and services with service-oriented architecture(SOA). By neutral interface definition and description among the services, the loosely-coupled applications and services were processed by distributed deployment, organization and application, and the Digital Border-land service platform was finally developed. The main research work of this thesis includes:(1) By the analysis on the data originations of the Digital Border-land data were deeply dissected. The data model of the geo-environmental information and the relational model of the border-land situation information were designed. After studying the concept of data cube, the multidimensional border-land data cube was established and the Digital Border-land data model was designed.And the comprehensive peripheral geo-data base was designed, too.(2) Based on the characteristics of variety and complexity of the integrated data and applications by the service platform, the relevant services such as border-land geographic information were analyzed and designed from the aspects of the content, the professionalism and the service relations, and the three-level service framework model including service integration, service building processing and the aggregation of applications and services. The multiple service mechanism of border-land geo-environmental applications and services was designed with a combination of the features of neighboring diplomacy.(3) The general design idea of the platform was elaborated with the division of the platform into three layers including data presentation layer, service logic layer, data layer, together with detailed design and analysis of the main implementation methods on the service side and on the browser side.
