Abstract

The invention provides an XML (Extensive Markup Language) data storage method based on a route structure. Compared with the prior art, the technical scheme has the following advantages: on the basis of the prior art, the XML data storage method and an XML data storage device based on the route structure realize the unique node data storage scheme by utilizing the route information, can realize high-efficiency data query and update operation, are more efficient and reliable, and can obviously improve usability and extendability. Due to the application of the technical scheme, query of XML data, length of the update route and complexity of an XML document per se are not involved, and the cost of route query is constant under any condition, so that the query performance can be obviously improved to the XML document with the complex structure and the XQuery query with longer route; and meanwhile, metadata of the XML document is stored independently, so that the node names are avoided from repeating, and data query and update performance can be obviously improved in the database management application examples with huge data quantity.

Description

technical field [0001] The invention relates to the field of data storage, in particular to an XML data storage method based on path structure. Background technique [0002] With the continuous in-depth development of the modern information industry, the demand for information integration and sharing has become increasingly urgent. XML (full name Extensible Markup Language), a markup language specially designed for the internet. The focus of XML is not on the form of data itself, but on the management of data information. Therefore, XML makes it possible to unify different database modes and provides a way for the integration of heterogeneous databases. Therefore, XML has been developed and widely used in recent years. [0003] XML database management system (XMLDBMS) is also a new type of database management system that has developed rapidly in recent years. It is a database management system that stores and retrieves XML document data that conforms to W3C standards, and ...
