  • Abstract
    The paper studies "equality" in XML model decomposition. XML IFD, TFD, AFD and MVD are proposed. According to complexity of these FDs, four XML normal forms are presented. FD maintenance and lossless join decomposition of DTD are defined to analyze "equality" of decomposition. Four lossless algorithms are proposed to decompose DTD into some XML normal form and validity of these algorithms is analyzed.
