Abstract

The invention provides a storage method of an XML document. The method is a new storage method aiming at storage problems of a great amount of small XML documents which are similar in form by effectively utilizing a distributed storage system HBase on a cloud computing platform. In the new storage method, the invention discloses a bidirectional data mapping model from a great amount of XMLs to Hbase; during construction of the model, a new XML document node coding method in which route information is integrated with node position information is provided; the coding method is excellent in node relationship judgment capability, can also solve the defect of a traditional SML coding method in aspect of code updating, and also provides good support for compressive storage of a great amount of SMLs which are similar in structure.

Description

technical field [0001] The present invention relates to database technology, in particular to a method for storing Extensible Markup Language (eXtensible Markup Language, XML) documents. Background technique [0002] With its self-describing, extensible and semi-structured characteristics, XML has become the most popular standard for information representation and data exchange, and has been widely supported and applied in various fields. Especially in the environment of the Internet of Things, most of the data are numbers or texts with certain meanings, and the good semi-structured information expression ability of XML in syntax provides a good foundation for it to become the data exchange standard of the Internet of Things. Currently popular Internet of Things data exchange standards such as BITXML and Physical Markup Language (PML) are all based on XML. However, millions of sensor networks or smart terminals are generating data all the time, and a single data file is gen...
