Problems solved by technology

[0004] (1) In practical applications, there will be a large amount of multi-source heterogeneous data, that is, data with multiple sources and different structures. Multi-source data such as GIS (Geographic Information System, Geographic Information System) data format, office document format, image data format; for GIS data, data conversion, interoperability, direct operation, etc. will increase the difficulty of software development and the burden on users; heterogeneous data such as Oracle database, SQL Server database, and the existing directory tree can only manage specific data, Unable

Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0036] Such as figure 1 As shown, a specific embodiment of the rule-based dynamic directory implementation system of the present invention includes a data entry device 101, a directory rule designer 102 and a directory rule analysis operator 103, wherein:

[0037] The data entry device 101 is used to receive the naming rule formulated by the user, and parse the naming rule into a regular expression; then match the regular expression with the data in the user's data source, perform data screening, and extract valid data ;Then decompose the file name of these valid data into the fragments specified in the rule, map these fragments to the fields in the specified database table, and w...

Abstract

The invention discloses a method and a system for realizing active directory based on rules. Directory rules are set by a user; extend markup language (XML) files used for describing directory rules are generated by a directory rule designer according to the directory rules set by the user and corresponding fields in a database table; and the XML file is interpreted and run by a directory rule running interpreter, so as to obtain a dynamic directory tree. A dynamic data directory provided by the invention provides the user with the method for effectively managing multi-source heterogeneous data, particularly managing spatial data; and the invention has the advantages of dynamics, real time for users and randomness of application demand.

Description

technical field [0001] The invention relates to directory management technology, in particular, a method and system for realizing a dynamic directory based on rules, especially a method for realizing a dynamic directory suitable for managing spatial data. Background technique [0002] With the development of science and technology, the amount of information is increasing geometrically. It is very difficult to quickly and accurately obtain resources that meet the needs from a large number of available resources. For example, with the development of computer networks and the deepening of information integration, the demand for geospatial data sharing is intensifying. Users are eager to quickly obtain geospatial data that meets the requirements. It takes a lot of effort to find the data you need. In order to give full play to the role of existing data, improve its utilization efficiency, and save expensive costs for more data generators and data users, it is necessary to effec...
