Method and system for implementing dynamic catalog based on regulation

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...

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 to manage multi-source heterogeneous data;

[0005] (2) Most of the existing directory trees are single static directory trees with fixed themes or groups, which cannot be flexibly customized to display and manage spatial data and non-spatial data at the same time, nor can they express multi-level topic grouping information resources;

[0006] (3) The directory tree management method is widely used, but there is no general development specification. Developers generally develop a directory tree management system for each application, resulting in serious repeated development and waste of resources.
