Forest resource heterogeneous data distributed management system

Abstract

The invention provides a forest resource heterogeneous data distributed management system. The system comprises a data management module, a service management module, a data service release module, a metadata service module, a metadata registration module and a catalogue and index module, wherein the data management module maintains distributed data stored locally by a data provider and collected by a network; the service management module provides service data; the data service release module acquires and matches the distribution data and the service data so as to generate data service release information, and releases the dynamic deployment of the data service release information to a server; the metadata service module generates data service metadata according to the data service release information; the metadata registration module eliminates the isomerism of the data service metadata through the conversion of a private format, and generates standard metadata of the system; and the catalogue and index module provides catalogues and indexes for the standard metadata of the system. The forest resource heterogeneous data distributed management system realizes the distributed management of the forest resource heterogeneous data of a forestry center.

Description

technical field [0001] The invention relates to a data management system, in particular to a distributed management system for heterogeneous data of forest resources. Background technique [0002] With the rapid development of computer, database, network and other technologies and their wide application in forestry, the forestry industry has built many application systems from national to local, from production management departments to research institutions. The forest resource data management system is part of the digital forestry public technology platform in the "Digital Forestry Platform Technology Research and Application". The lower-level departments submit standardized data to the higher-level digital forestry platform to provide a basis for the analysis of major national forestry decisions. Most of these systems are self-developed locally, and the database management systems used are different, and the structure of the database is also inconsistent. As a result, var...

Problems solved by technology

Most of these systems are self-developed locally, and the database management systems used are different, and the structure of the database is also inconsistent. As a result, various application systems cannot be interconnected and shared, forming isolated islands of information, resulting in difficulties in information sharing and integration. , information transmission is not timely, inconsistent, and information utilization rate is low
