XML based industry information sorting and mapping method

Abstract

The invention provides a classifying map method for industry information based on XML (extensive makeup language). The method utilizes XML to describe industry information classification standard and information unit data, and establishes a classification tree according thereto, dynamically extracts database inquiry code according to user needs, and utilizes a standard database procedure execution mechanism to improve the work efficiency of an industry information application system. The method comprises the following steps: (1) loading a description file and establishing an industry information classification tree; (2) driving traversal information classification tree to obtain classification node by information needs; (3) dynamically loading the database inquiry code when the node state indication is false, and setting the node state indication as true; (4) directly accessing the inquiry code corresponding to the node when the node state indication is true; (5) and conducting data inquiry procedure and acquiring data set. The work flow of the method is displayed as the above diagram. The method realizes the mapping to the industry information with large data amount and multiple classifications with the mode close to the need of industry user, thereby effectively increasing data retrieval efficiency and strengthening system expansibility.

Description

[0001] Technical Field: The present invention is an XML-based industry information classification and mapping method, which belongs to the category of information technology. technical background: [0002] How to enable the industry application information system to effectively exchange and efficiently share heterogeneous information with large amounts of data and multiple varieties is a hot issue currently concerned by the software industry. In the development of industry application information systems, scenarios used for querying complex statements are often encountered in database applications, which generate a large number of requests to the database server during the query process. Moreover, in general, the user only cares about the relevant information he needs, so every time a query is submitted, even if the same type of information is needed, different query strings will be used. If the system uses different query characters or keywords for the user The query code performs...

Moreover, under normal circumstances, users only care about the relevant information they need, so even if they need the same type of information each time they submit a query, they will use different query strings. The query code performs matching queries in the database. When these queries are executed, the database server will repeatedly consume a large amount of system resources in the process of compiling the code, executing the program, traversing the data, and finally outputting the result data set.

This data query method affects the efficiency of database retrieval
