Gis Key · Journal of Capital Normal University · 2005
There are some problems about solving the inter-access of heterogeneous data sources with the strategy of common database access technique,which are high system complexity,low system extensiveness.In this paper,the author set forthe that how to solve the questions of exchanging and sharing in data,by studying several kinds of relatively popular data forms at present.Considering systematic extendible qualities and network transmission requests,the author proposed the XML communication model of heterogeneous data sources which include the using middle data source.This model is the general model which include the treatment methods to the different data communications,on the base of XML have its peculiar advantages in data base share and joint field.The model has been successfully applied to converting virtual reality modeling Langualge(.wrl) data.
