<P>PROBLEM TO BE SOLVED: To provide a method for storing in compact, analyzing at a high speed, updating, and preparing a structured document having the giant number of storages of information containing much graphical information and giant data size. <P>SOLUTION: The structured document is separated into a compressed schema section and a compressed data section. Only a text element being individual information on the structured document, an attribute value, and the frequency of duplication are stored on the compressed data. The others are stored on the compressed schema section. Furthermore, the size is reduced by forming the text element to a dictionary, applying a variable-length numerical value, and relative value management. The method provides a means for analyzing, updating, and preparing the structured document by using SAX, DOM being standard interfaces. and a means for changing the structure in one operation by updating compressed schemer without updating a large amount of the compressed data. The method allows the preparation of the structured document having high expandability and high-speed data analysis. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
