Query management method and system of pure extensible markup language database

Abstract

The invention relates to an inquiry management method and an inquiry management system for a pure XML database, and belongs to the technical field of inquiry management of the pure XML database of a computer. The inquiry management system for the pure XML database comprises a data file management module and an inquiry operation module, wherein the data file management module is used for processing data and recording and storing the XML data into various slots of web pages; each web page has a unique page number and each slot in the web page has a unique slot number; the 'page number' and the 'slot number' are used for uniquely positioning the position of a record; web pages for storing the same XML file data are connected with each other to form a doubly linked list by pointers of page heads; a node storage structure comprises a code domain which is used to be endowed with a code value by a relation analytic unit; and the inquiry operation module is used for realizing inquiry operation and executing structure linkage operation, and comprises the relation analytic unit and a structure linkage unit. The inquiry management method and the inquiry management system have high time performance, can greatly improve the inquiry efficiency, and are convenient for realization and application.

Description

technical field [0001] The invention relates to a query management method and system for a pure XML database, and belongs to the technical field of query management for computer pure XML databases. Background technique [0002] In order to overcome the shortcomings of HTML technology and SGML technology, XML technology emerged. The full name of XML is eXtensible Markup Language (hereinafter referred to as Extensible Markup Language), which is a markup language specially designed for the Internet. The focus of XML is the data itself of the management information, and the display of the data is left to other technologies. It can be said that XML technology has heralded its brilliant future since its birth, especially with the vigorous development of Web Services in recent years, XML has become more and more active in the field of data exchange and storage. [0003] At present, XML has become a new standard for data representation and data exchange on the Internet. It can cre...

Problems solved by technology

The former has the following disadvantages: XML documents need to be "broken" when stored in the database, and "combined" when taken out, which is time-consuming and may cause errors. This problem is called "impedance mismatch"; Schema conversion is complicated; existing databases have poor processing performance for document-centric and complex-format XML documents; the adopted XML technical standards are relatively backward

The latter has the following disadvantages: it is relatively weak in traditional database technology and has not passed the test of time; the knowledge is relatively new, and the corresponding support staff and document resources are relatively small; the application scope is limited to the XML application field
