| Abstract: | Radical problem of historical data archiving in date warehouse is analyzed,applying XML into archiving.Arithmetic of getting information about structuring XML pattern from data and arithmetic of structuring level direct graph are provided.The arithmetic of mapping from data base structure to XML schema based on level direct graph is implemented.In the meantime,the ways is provided to ensure XML semantic integrity. |
