摘要：Background: This study proposes a new dynamic coding scheme- the three-dimensional XML coding based on cone, on the basis of the static coding scheme is extended, can effectively support the XML document update at the same time under the condition of the document is not updated with good performance. Materials and Methods: Solved the coding efficiency is low and the system cost is high caused by the entire XML tree need to re-encode when the document updates and solved the problems, such as the time and space overhead of the traditional dynamic coding scheme. Results: Due to the introduction of aspect-oriented thought, therefore, this study on the basis of analysis and comparison of the existing structural join algorithm, based on merging thought to solve structural join under multi-documents, proposes a structural join algorithm is suitable under multi-documents and can further reduce the cost of connection scanning by weaving document properties or index. Conclusion: Design the corresponding experiment and prove the document defines method, the coding scheme and the corresponding structural join algorithms proposed by this study have better performance and feasibility.
