| Abstract: | On the basis of the analysis of temporal information's influence on data validity and data processing authorization,this paper presents a method that organizes temporal relation data table based on the relation of temporal data value and related data validity,data processing authorization.Then the database can be organized by integrating it with table formed by temporal data and normal data.In system processing,it adopted uniform database inquiry processing method to complete processing information system varies with time. |
