Indexing technique is significant for efficient XML data processing.A majority of existing index and storage strategies make against structure querying and updating XML which are at the cost of dropping of structure information.As the standard for describing document structure information,XML Schema provides a guarantee to validating the XML data and query path,herein Schema-based Constrained XML data indexing technique SBXI is suggested which can navigator data storage and query,improves the efficiency of data management.Moreover,this technique has upper space utilize efficiency and lower maintenance index expense,and sustains complex query of multi-predicative which do without traversing document tree.
