| Abstract: | The effective physical storage is the base for information system development of the land and resource data.Firstly,the characteristic and requirement of the land and resources data management of a province is analyzed in this paper.Then the application model and physical storage strategy is studied in detail.Taking the land and resources data of Shaanxi Province as an example,the data analysis performance is tested and analyzed under three different physical storage strategies,which includes the multi-instance for a county,single instance for a province(no layout control) and single instance for a province(with layout control).In the end,the conclusion is achieved which has valuable reference for other provinces of China. |
