Mass uncertain XML data storage method

Abstract

The invention discloses a mass uncertain XML data storage method. The mass uncertain XML data storage method comprises the following steps that A, extracting mass uncertain XML data; B, constructing amass uncertain XML data representation model based on a column database; C, realizing massive uncertain XML data storage based on the uncertain column database. The uncertain XML data representationmethod based on the column database is researched by identifying the multi-granularity uncertainty of the data in the uncertain XML document; a storage model for massive uncertain XML data is researched; a mass uncertain XML data storage method under the condition that a research mode (XMLDTD / Schema) is known is included. According to the method, the representation and mapping storage method for the mass uncertain XML data is developed, so that the problem that the mass uncertain XML data is difficult to manage is solved.

Description

technical field [0001] The invention relates to the technical field of XML data storage, in particular to a method for storing massive uncertain XML data. Background technique [0002] Possible world theory and possibility theory are methods for the quantitative representation of imprecise and uncertain information, and have been widely used in the extension of database models since they were proposed to realize the representation and processing of imprecise and uncertain information. In recent years, with the development and application of computer technology, the research on possible world theory and possibility theory for conceptual data model extension has attracted the attention of researchers, and it shows a trend of combining with XML database. In order to express uncertain information in the XML data model, researchers at home and abroad have gradually begun to increase the research on extending the semantic expression ability of the XML data model, and proposed a va...

Problems solved by technology

Because traditional data storage methods are difficult to cope with the explosive growth of massive data, how to effectively store and represent massive uncertain XML data is still one of the problems faced by current research.
