| Abstract: | This paper put forward the project to manage the defence data and information effectively based on Geodatabase.It defined the classifying,coding and naming of Geo-data according to the GIS spatial data standard.And it recreated the necessary geometrical network and the network of the geography features according to the spatial relation of these geography features.At the same time,it also provided the feasible data security policy and effective database backup mechanism.Finally,this paper designed a integrate data quality controlling system. |
