In recent years, the method of assigning labels to the node of XML tree is getting more attraction. Various fanctions in an RDBMS can be easily utilized by storing the labeled XML documents into the RDB. However, in simple labeling methods, a number of nodes need to be re-labeled, when the XML documents are updated frequently. To avoid this, we proposed DO-VLEI method combining VLEI code with the Dewey Order method. Compressed-bit-string DO-VLEI created by applying DO-VLEI on bit string has a variable length. In order to derive the length, we have to provide the size of code at the head of the string or a terminal symbol at the end of it. In this paper, we propose improved compressed-bit-string DO-VLEI labeles to handle the length efficiently, and compare the storage consumption of the labels with the wellknown ORDPATH. |
